SUMMARY OF REPORTED PESTICIDE INCIDENTS INVOLVING 2,4-0
Pesticide Incident Monitoring System
Report No. 2S3
by
Health Effects Branch
Hazard Evaluation Division
Office of Pesticide Programs
Environmental Protection Agency
March 1980
-------
STNOPSIS
"The files of tfce Pesticide Incident Monitoring System (PIMS) were" searched
for i epui l£ involving 2,4-0, active ingredient 2,4-dichloro?henoxyacetic acid. It is
also known as CAS 94-75-7. At the tine of the search, the files contained 33,525
• incident reports covering the period from 1966 to M arch 1980; of these, 1,001 involved
5,4-0.
Two croups of reports were distinguished in these incidents in which alleged
adverse effects were reported. One group containing 600 reports cited the
involvement of 2.4-0 alone. The other contained 401 reports and cited 2.4-0 in
combination with other ingredients.
The presentation of Information regarding incident exposure circumstances
and effects in this synopsis is made with no reference to whether the occurrence has
been confirmed to be the result of pesticide involvement or not. This is not to say
that all cases reported in this sum m ary lack confirm ation. Neither should the absence
of confirmation be interpreted as weaning that the reported effect was not caused by
the pesticide. Rather, it may intricate only-that confirmatory materials have not been
submitted for incorporation into the Pesticide Incident Monitoring System. Incidents
contained in this sura nary include only these which have been resorted to PIMS. It is
likely that ether have occurred and remain unrepcrted; therefore, this number should
be thought of as representing a minimum.
PIMS data, involving 2,4-0 is presented in three tables. In each table it is
shown whether the involvement of the pesticide was alone or in combination with
other ingredients. Table 1 shows the number of reported incidents by entity and stte.
Table 2 by sits and circumstance. Table 3 presents an abstract of each incident and
various data related to the incident.
In the 128 incidents involving humans and 2,4-0 alone, there was one fatality,
18 persons were hospitalized, 92 received medical attention, and 46 were affected but
not treatad. There were 3 fatalities in the 195 incidents involving 2.4-0 In
cam fain ation, and 25 hospitafizstlons; 324 persons recsived medical attention ano 124
were affectad but not treated.

On 9/1/66, a legislator requested an investiga-
tion of damage to cotton crops by herbicide
drift which occurred in 1954. The spraying
operation was carried out along a river by the
Army Corps of Engineers. Damage occurred
in five parishes and resulted in several claims
for compensation.

Twenty-two 55-gaIlon drums of 2,4-0 and two
SB-gallon drums of 2,4,5-T (diesel oil #2 as
carrier) were applied at the rate of 2 Ib
herbicide/2 gal oil/acre in an aerial applica-
tion to control sage brush and other brush on
privately owned sheep and cattle rangeland.
The rangeland was adjacent to two small
towns and in fairly high and steep rolling hills
south and east of the towns. The crop and
range damage occurred at the south end of a
valley which narrows considerably with several
canyons and ravines leading from the treated
• area to the crop and rangeland surrounding the
towns. After the applicator spent the greater
part of the day spraying, farmers and property
owners claimed that the daily canyon breezes
carried "considerable* chemical drift down to
the valley. Oam age was evident in the wheat
and alfalfa; the wheat (watered by sprinkle
irrigation) had twisted growth and died in
patches. Grass was stunted, had streaks of
-------
black, and had not produced seed; mustard,
burdock, yarrow, sunflower, dock, stinging
nettles and other plants also had twisted
stems. Boxelder and maple trees, choke
cherry and service berry shrubs were burned or
kitted. The burning of the trees and shrubs in
a any Instances occurred only on the east or
mountain side of the area. In leaf regrowth
the petiole was twisted, the leaf distorted.

In 1965, leftover 2,4-0 was placed in a used
maleic hydrazide container and not relabeled.
On approximately 6/16/66, the improperly
stored 2,4-0 was mistakenly ground-applied
for tobacco sucker control at a rate of 4
lb/acre. The herbicide was applied to the
well-drained, 1 3/4-acre field by a tenant far-
mer in calm, dry weather. The extent of

co was later salvaged. Similar incidents were
reported to have occurred previously in the

A 48-year-old truck driver ingested one cup of
herbicide in a successful suicide attempt. Ac-
cording to his son with whom he lived, he had
been despondent due to marital problems. The
50-gallon drum from which the pesticide was
taken had been sealed. The drum was stored
in a garage at the driver's place of employ-
. nent; whether he ingested the herbicide at the
garage or took it home before ingestion was
undetermined. Ingestion was between 6:30
a,m. and 7 a..u. At home shortly thereafter,
he became nauseated and vomited, for which
he took aspirin and a glass of milk at that
time. He was found sitting in a chair in a
dazed condition at 7:30 a,m., and admitted
drinking the pesticide. An ambulance was
called; he was admitted to the hospital at 9
a,a. (4/1/67), stlTl conscious. He died at 5

a.m. on 4/3/67. Laboratory analysis of liver,
stomach and intestines confirmed the presence
of 2,4,5-T and 2,4-0.

soil contaminated 2,4,5-T (ester)
A veterinarian stated the dog's death was due
to contact with the pesticides. An electric
company used herbicides for weed control
under power lines. Some of the product was
sprayed within the fenced area of a private
residence, approximately 36 feet from the
house. Approximately 15 minutes after the
application, the resident's pet dog (Blue Tick
hound) roamed over the sprayed area within
the fence. The dog's paws were washed im-
mediately. Several days later, the dog was
observed liclcing his paws; all four paws were
found to be swollen. A secondary infection
developed in the injured paw area (the herbi-
cide allegedly "had eaten* into the flesh be-
tween the cushion and toes). During the next
year, the dog's owner consulted two veterinar-
ians in efforts to successfully treat the ani-
mal. Approximately two weeks prior to the
dog's death the problems seemed to be alle-
viated. On 10/17/68 internal bleeding oc-
curred, followed by death. The owner was told
by the second veterinarian, who had been
treating the dog for several months, that the
herbicide had been introduced internally
through the dog's licking his paws. Blood was
discharged from his mouth, anus and was in
the dog's urine. No post-mortem examination
was performed. The owner was making an
attempt to stop the sale of the product in his
state. A local sales representative reportedly
had stated that the product used was from "a
bad lot." The applicator's insurance company
made a payment for damages to the dog's
owner; label directions were not followed and
the application reached an area other than the
target area. One of the manufacturer's chem-
• ists responding to the owner's complaint stated
that the product was nontoxic and harmless to
humans and animals. The product label ad-
vised against contaminating water for irriga-
tion or domestic purposes: "Harmful if swal-
lowed. Avoid contact with skin, eyes cr
clothing."

Endrin
Extensive aerial applications of a combination
of endrin and 2,4-0 butyl ester to winter
wheat took place in eastern Colorado during
April, 1968. Similar applications of 0.25
Ib/acre endrin and OJ - 0.5 Ib/acre 2,4-0 were
made at two ranches on 4/15 and at a third
ranch on 4/16. A herd of Angus cattle grazed
on treated wheat at the first ranch on the day
following spraying. That afternoon, some of
the cattle developed staggering, loss of coor-
dination, opisthotpnus, and convulsions. Three
of the cattle expired by 3 p.m., and 14 others
were treated by a veterinarian between 3 and
5 p.a. At the second ranch, same of a herd of
35 Angus cattle grazed in a freshly-treated
wheat field located just north of their pasture.
Six cattle (including a calf) expired in the
early morning following spraying; seven others
received veterinary treatment. At the third
ranch, approximately 52 hereford yearlings
(heifers) were pastured between two fields
treated on the afternoon of 4/16. Ten to
twelve of the cattle exhibited mild excitabi-
lity on the morning of 4/T7; all recovered with
no veterinary treatment. Some of the treated
cattle received phenobarbital to control cen-
tral nervous system symptoms; others were
treated extensively with sodium thiosulf ate by
intravenous injection. Blood and milk samples
were collected from affected Angus cattle at
the second ranch. Tissue and rumen content
samples were obtained from a dead caw.
Serum endrin residues (methanol serum ex-
tract) in four cows ranged from 0.136 ppm to
0.259 ppm. ' A raffle sample contained 0.446
ppro endrin (Burchfield vol I, n A4a 1). Rumen
contents (entirely freshly-ingested wheat) con-
tained 0.257 ppm endrin (Burchfield vol L, HI
A3d 1), while liver and adipose-abdominal
•tissue contained 2.464 ppm and 2.322 ppm
endrin, respectively (Radoraski method).
Wheat from a treated field contained 52.718
ppm endrin (fresh weight basis). A diagnosis
of endrin poisoning was strongly presumed;
hypomagnesemic tetany ("grass staggers") was
ruled out. Magnesium and calcium electrolyte
levels were found to be in the low normal
range in serum from two cows. Nitrate poi-
soning was ruled out on the basis of 0.195
-------
nitrate (dry weight) detected in sprayed
wheat. Analysis of the pesticide emulsifiable
concentrates demonstrated the concentrations
on the product labels to be nearly correct.
Application rates were •determined to have
been reasonable. ~

Trysben
Thousands of acres of wheat fields surrounding
the complainant's residence were commonly
treated with herbicides each year for eradica-
tion of alfalfa and morning glories using
various brands of 2,4-0 as weTl as occasional
spot applications of Trysben. On 3/5/63 the
only application of 1963 was made (3 Ib/acre
2,4-0 amine on 200 acres). The application
was approximately % mile west of the home
and wind was practically nil according to the
aerial applicator. Affected residents de-
scribed the weather as windy. A flagger was
on duty during the application. The female
resident noticed a spray drift through her yard
and immediately experienced nausea and diz-
ziness, followed by loss of appetite, vomiting
of blood, and an inability to urinate for 2 to 3
days. Her family physician noted generalized
aching and feeling of illness, chest congestion,
eye inflammation, poor appetite, and extreme
nervousness. Antibiotic treatment produced
no response. She also was treated with sulfur
tablets. A second physician was consulted,
and noted chest pains, general malaise, and
loss of appetite. Laboratory results of blood
tests were mainly negative. A kidney infec-
tion was detected which responded to anti-
biotics. The doctor reported "... he couldnt
positively rule out the possibility, but neither
did he have any indication that she has been
affected by 2,4-0." The woman's husband also
-reported unspecified illness on tne day after
spraying. The woman reported horses were
affected; a veterinarian did not see the horses,
but provided a telephone consultation for one
sick animal. He felt the symptoms described
to him were related to laminitis, for which he
prescribed cortisone with vitamin 0 and selen-
ium. The horse, which had a history of several
episodes of laminitis over the past few years,
responded well to treatment. The woman

Eptam
Over tan farmers complained of damage to
their corn crops after use of the same granular
herbicide product for weed control. In all
instances, the product had been applied within
label-recommended rates, from 2.7 to 4
Ib/acrts. The farmers contacted denied using
the product in combination with fertilizers,
insecticide, or fungicides. The soils involved
were tight loam, loamy, or clay soils. Three
fields were investigated and samples were
collected. The stands of corn were described
as "spotty." Damaged plants had twisted,
curled leaves, abnormally shaped tap roots
("very triangular"), and anchor roots which
were few in number, thin, twisted, and weak.
Three T-pint soil samples were analyzed on
6/27; 0.2 ppm eptam was detected in one
sample. No 2,4-0
acid was detected in any of the samples. Gas
chromatography (with FID) was the method of
analysis; limits of detection were 0.15 ppm
eptam and 1.1 ppm 2,4-0 acid. The test
method was considered inadequate in that very
low residues could not be detected. The time
interval between use of the product and analy-
sis was not reported.

been-"sprayed to the point of run-cff." On
7/28/69, a neighboring farmer stated his Hoi-

had died. A veterinarian who observed the
Angus herd reported they showed typical
symptoms of arsenic as wen as nitrogen poi-
soning." A second veterinarian who had ob-
served ~both-herds agreed with the first. Two
more cows from the Holstein herd died on 8/5.
Samples werejtaken from cows of the Holstein
herd and sent- to a private laboratory along

A farm pond situated in the center of a large
pasture (no cropland for a distance of at least
k Rile) was treated with 202 2,4-0 granular
herbicide in the early spring of 1969 for con-
trol of aquatic vegetation. The application
conformed to label Instructions. In April, the
surrounding pasture was treated wtth approxi-
mately 600 pounds of commercial fertilizer
03-13-13). In June, the farmer's son observed
several mutated frogs while swimming in the
pond. Defects included "cyclops* eyes, abnor-
mal number of appendages, poorly developed
muscles, and others. Investigation of the
incident was delayed until October, when six
frogs (apparently normal) were collected from
the pond along with four pints of water. Since
efforts to collect a mutated frog had proved
fruitless, the farmer provided a live frog wtth
Ixo additional hind limbs which his son had
been keeping in an aquarium (photo available).
Samples were forwarded to a federal labora-
tory for analysis. Approximately 2,500 ml of
the pond water was filtered to obtain a sedi-
ment, which was found to contain an organic
chlorinated m aterial which could not be iden-
tified as one of the common chlorinated pesti-
cides. Two of the normal frogs were found to
contain approxim ately 0.1 ppm ODE and traces
of dieldrin (0.01 ppm). The six-legged frog
contained approxim ately 0.2 ppm 0 0 T-0 0 E-

plex. Foliar spray tests,"in which 3-week-old
tomato seedlings were 'sprayed with pond
water, resulted in no significant plant injury as
compared with 2,4-0 standards and distiHed-
water controls. Root growth tests revealed no
Inhibition of root elongation in seeds treated
with pond water, also compared with standards

area. Spraying was discontinued whenever
wind speed exceeded 10 miles per hour. The
helicopter flew 20 -100 feet above the vegeta-
tion while spraying; it avoided as much private
land as possible. A nozzle clogged during one
application. A recreation- area and stream
bottom vegetation within the treatment pro-
ject were avoided. There was a lade of

Observers also reported rapid exfoliation of
sycamore bark, unusual growth appearance of
prickly pear cactus, and high IB ortality of such
shrubs, as yucca. At a camp ground, standing
water was rust colored. During one inspection
of the area, an English sparrow appeared with
swollen eyelids and dying at one home; this
seemed to be a farafHar experience to the

A possible disuse of pesticide was suspected
to have caused both physical and mental dis-
ability in two of three children. In August of
1969 a 0-raonth) pregnant mother and her 46-
month-old daughter were in their back yard
when a nisi was created by a neighbor spray-
ing herbicide in his yard (used a hose-end
sprayer). The two had remained in the yard
approximately an hour. It was hot, not humid,
and there was a slight breeze. The mother
almost lost consciousness when she went into
her house; at that time she noticed the yard
was filled with mist. Her daughter began
exhibiting convulsion-like behavior (eyes rolled
back, tongue extended and sitting Urn ply). She
was rinsed with water and her clothes
changed. A physician was contacted; he
recommended observation of the child and
removal from the area. The pregnancy re-
sulted in a boy who is highly sensitive to
chemicals and has a severe allergy condition.
The child has stopped breathing in his sleep
and turned a black color; resuscitation has
kept him alive. Subsequently he has had
"black blotches* under his skin. The mother
feared teratogenic defects in the child. A
third child, 18-months-old, born since the inci-
dent, is normal. At the time of the incident,
an EPA misuse regulatory group was not in
effect and EPA had no jurisdiction. She
requested aid in compelling her neighbors to
inform her prior to applying pesticides and
fertilizers. She was advised that the EPA has
no jurisdiction if a product is applied in
accordance with label directions.

A newspaper article of 12/3 linked damage to
trees, shrubs, crops and home gardens in a
residential/com raerdal/agricultural area (in
and around a large urban area) to emissions
from a 2,4-0 formulating plant located in the
area. Oam age was reported to have occurred
during a period from late April to early July; a
spokesman for the formulating plant was re-
portfcvi in the news article to have stated that
the plant was idle during this period. Investi-
gators were hampered in their efforts to iden-
-------
tify herbicide damage because of the season of
yean leaves had already dropped from trees,
and gardens and crops had been harvested.
County personnel were interviewed regarding
specific reports of damage which they had
investigated. On 6/24, a. county inspector
attributed herbicide damage in trees on pri-
vate property to drift from a commercial
spray plane, and further stated that he knew
*?* «? Instance of 2,4-0 damage which could
not be correlated with commercial use.
Another county official reported that herbi-
cide damage occurred in late June or early
July to a county vegetable garden project
located % mile north of the formulating plant;
it was learned that the county had recently
sprayed a roadside area adjacent to the garden
plot with 2,4-0. This inspector also reported
that all 2,4-0 damage he had observed could
be attributed to drift from commercial appli-
cations, and further stated that local weather
conditions (air current) favored wide dispersal
(at least 5 miles) of such drift. Samples of soil
and horseradish leaves/roots were collected on
12/5 from a farm at which 2,4-0 had not been
applied for several years. Analysis results
were not reported. The farm was located 3/4
mile northeast (downwind) of the formulating
plant; prevailing winds in the area were from

ney declined to provide information concern-
ing 2,4-0 production and plant emissions.

' Two herbicides, a liquid weed killer and a
pressurized spot weed killer were hand-
sprayed to destroy dandelions and buffalo
grass in the yards of a residence on 5/5/70.
After a drying period, four Dalmatian dogs
were allowed to run in the yard. Near mid-
night of 5/6/70, one bitch (65 Ibs, 2Vyears-
old) had a convulsion; a second attack oc-
curred early the next morning. The dog's
stools contained buffalo grass; the dog was
taken to a veterinarian who treated her for
epilepsy. On 5/8/70, he drew a blood sample
from the dog, who continued to have convul-
sions, and sent the sample to a laboratory.
The analysis report stated that the blood con-
tained components similar to or corresponding
to the spot weed killer. After the report was
returned, the veterinarian began treatment
with the universal antidote and 2-PAM. The
-------
convulsions worsened and the dog died 5/10/70.
The aredication for organophosphate poisoning
did not affect the dog in any n anner. At the
laboratory where the analysis was performed,
the taxicologist used a gas chro a atagraphy
and the "head space technique" in his testing.
It was concluded that such a method did not
prove the presence of a toxic a atarial in both
blood and herbicide and another laboratory
was unable to detect any contamination of the
two herbicides or the .presence of crgancphos-
phates. On 5/12/70 the dog's owner reported
that she was feeling ill and upset and her
physician was giving consideration to the pos-
sibility that her illness might be related to the

highway level and received drainage from the
road. A veterinarian unsuccessfully treated
the ducks for botulism. Two ducks that sur-
vived were nesting in adjoining fields and one
'was recovering from a broken wing. An en-
vironmental group froze one duck carcass and
two samples of pond water. A conservation
laboratory examined the dying ducks but did
no tests. The frozen duck carcass was sent to
a laboratory for testing. - The resulting report
indicated the duck was generally in excellent
condition and there was no gross evidence of
trauma. Com and other food was found in the
gizzard. There was no evidence of infection.
Mo cause of death was determined. The pond

(alder) MCPA
* Sodium chlorate
Sodium a elaborate
In a letter to an elected official dated 7/3/70,
a professor of forestry and a professor of plant
pathology reported having observed herbicide
damage to streamside vegetation along a river
canyon. They attributed tree deaths, partial
defoliation, and leaf curling to possible drift
from railroad right-of-way spraying and, more
likely, to drift from aerial applications to
farms located on a plateau above the river. A
state agricultural inspector investigated vege-
tation at several points along the river, and
stated that he found evidence of 2,4-0 expo-
sure in two areas: within a railroad right-of-
way, and in a group of alder trees located
approximately 10 miles upstream from the
rivert mouth. A railroad company had applied
27,300 gallons of diluted herbicide to approxi-
• ately ISO miles of right-of-way on 4/27-28-
29/70, beginning at the mouth of the river.
The herbicide contained 0.02 lb/gal MCPA,
1.75 lb/gal sodium chlorate, and 1 lb/gal sodium
• elaborate diluted at a rate of 1 gal herbi
cide/1 gal water. The application rate was
approxire ately 160 gallons diluted herbicide per
mile of railroad track, applied by boom
sprayer to an area extending 2 feet beyond tie
ends. On 5/14-15-16-21/70, an aerial applicator
had sprayed approximately 1,000 acres of pri
vate land with 2,4-0 (ester) for control of
• sagebrush and rabbit brush on grazing land.
Approximately 700 treated acres were located
within the canyon walls and included side can-
. yens and ridge tops. The rate of application
was 3 lb 2,4-0/5 gal dilution/acre. Thirty
acres of sagebrush on the opposite side of the
river, including a landing strip adjacent to the
river, were also aerially sprayed during the
same period in May. The state investigator
attributed alder tree damage to the sagebrush
spraying through one or more of the following
conditions: (a) minor drift during application,
(b) volatilization during or after application,
and/or (c) volatilization by accidental burning
of treated area (several brush fires had
occurred in the canyon wall). Herbicide
-------
damage to the alder trees was described as
"minor." Other tree deaths and damage
observed during the investigation were
attributed to old age, flooding, fire, and

spreader for hone garden and lawn. The

used. Label instructions were followed during
the application (the temperature was less than
75° with Ifttle if any wind), with the exception
of a watering of the back lawn earlier after
application than recommended by the label.
He watered the treated area daily; the lawns
turned brown which the owner believed was
due to nitrogen bum, but they did not recover
as fast as they should. Major portions of the
lawn were destroyed and subsequent migration
of the pesticides damaged nearby shrubs and
trees. The damage was confirmed by on-site
investigation, and included leaf wilting, defoli-
ation, and scorching, stem die-back and
brittleness, and partial root kill. Route of
exposure appeared to be systemic. The pro
duct was analyzed and was found to be chemi-
cally satisfactory. W ater had run off into his
neighbor's yard and had killed one of his neigh-
bor's shrubs. Damaged or destroyed plants in
. the treated yard included the following: orna
mental dogwood, flowering plum, silver maple,
lombardy poplar, and magnolia trees; rose,

A farmer applied 2,4-0 (ester) in water to
preemergent field corn at the label recom-
mended rate of 3J Ib/acre. He added more
2,4-0 than the label recommended but felt it
did a poor job of weed control in his field. The
ground-spray application was made in early to
old-May (exact date not reported) in mild,
humid, overcast weather; wind speed was ap-
proximately 5 miles per hour. The boom
height was approximately 18 inches from the
ground; the treated field was considerably
higher in elevation than residential property
. located directly across a highway from the
field. The residential site comprised approxi-
mately 4 acres and was partially enclosed by
bordering trees; the house was located 0.1 mile
west of the highway. Plant damage on the
residential property became evident 5-7 days
after the spray application. An investigation
of 2 acres of the affected property on 10/6
Indicated that drift from the nearty applica-
tion to a corn field was the cause of the
damage (described as 'moderate to severe").
Due to the lateness of the growing season,
some damage was masked by normal defolia-
tion and vegetative decline. Scarlet oak,
white oak, and black walnut trees were most
seriously affected, exhibiting extensive leaf
curling, malformation and leaf bum. White
pines in the area exhibited no damage. To ma-
-------
toes, beans, roses, forsythia, wisteria, and

curled and malformed leaves. The family re-
ported that no herbicide had been applied on

Forests, right-of-ways, and private property in
and around a town were sprayed with herbi-
• ddes using aerial, ground and hand-spray
equipment. Dates of application were nut
specified. In approximately 20-25 sections
surrounding the town (and including other
snail towns), typical hormone-type herbicide
symptoms were observed in trees and vege-
tables. An estimated IS - T%* of the tree
population appeared to be affected. Black
locust, mimosa, and sassafras trees (species
considered susceptible to hormone-type herbi-
cides) displayed yellowing of foliage, defolia-
tion, and twig terminal curvature. Sweet gum
trees exhibited leaf cupping. Foliage was
yellow or dead on several oak, hickory and
sumac trees. Tomatoes, peas, and other vege-
tables in several gardens exhibited leaf proli-
feration and strapping, leaf cupping, and
- pointed fruit. An ester of 2,4,5-T was applied
by fixed-wing Aircraft to a forest located (at
nearest point) approximately l*j miles south-
southwest of the town. The forest crossed a
mountain range 1,200 - 1,500 feet in elevation.
Wind velocity and temperature were expected
to produce minimal drift; a V mile buffer zone
was spared. Hormone-type herbicide symp-
toms were evident in susceptible vines and
trees throughout the buffer zone, and between
the buffer zone and the town. Symptoms were
' less pronounced as distance from the target
area increased. Another forest, located 9
niles southeast of the town (and 4 miles south
of another town), was sprayed by helicopter.
The herbicide used was not reported. Herbi-
cide symptoms appeared in trees and gardens
near the sprayed area. No appreciable symp-
toms were evident in the zones between the
two forest sprayings. A railroad right-cf-way
passing directly through the town was treated
with 2,4-0 (amine), bromacil, and dalapon (so-
dium salt) applied from a railroad spray car
for brush, weed and grass control. The 2,4-0
(amine) was applied inadvertently, according
to the custom applicator. Hormone-type herb-
icide symptoms were particularly evident in
-------
susceptible woody species. Power line right-
of-ways were grcund sprayed with 2,4-0
(aurine) and picloram (amine), except for two
snail, inaccessible areas comprising 25 acres
which were sprayed by helicopter. Ground
spraying, at its nearest point, took place 2
miles north of the town, while the two aerial-
ly-sprayed zones were located 6 and TI miles
northeast of the town (two other snail towns
were situated a mile northwest of the aerially
treated areas). Herbicide symptoms were con-
fined to within a short distance from target
areas. An individual applied 2,4-0 (amine) to
a 1 - 2 acre pasture adjacent to the treated
railroad right-of-way for the purpose of weed
control, with poor results; a knapsack hand
sprayer was used. Nearby herbicide symptoms
were similar to others observed. Another
individual applied bromacfl for grass and weed
control along a fence line on private property.
AH vegetation within a 3-foot-wide band was
killed. Oak and hickory trees located 9 - 25
feet from the bank displayed severe foliage
damage. Root absorption of herbicide was
suspected of contributing to the damage. Spe-
cimens of mimosa, ash, and black walnut were
analyzed for the presence of pathogenic infec-
tions; results were negative. Afta* a 2-fflontn
investigation, hormone-type herbicide from
the forest spraying and from the railroad
right-of-way spraying was determined to be
. the principal cause of defoliation, yellowing,
and leaf cupping of susceptible woody species,
and of the leaf strapping and fruit effects in
vegetable crops. It was theorized that condi-
tions did not readily permit the material to
penetrate the target area cover, and the fine
portions remained suspended and later drifted
to adjacent areas, and/or that the ester volati-
lized after application and the vapor drifted
.by air currents. Effects were more pro-
nounced in a "draw" running through the town,
which indicated a settling in lower places.
Within a few weeks after the investigation,
• ost trees had regained their foliage, with the
exception of previously weakened or stressed
trees, and the oaks and hickories which were
severely affected along the treated fence line.
Reductions in yields from affected gardens
were undoubtedly experienced.

An aerial herbicide application was to be made
to 200 acres of county land and some private
farm land. The permit for spraying was given
to the private farmer's father who was in-
structed not to use 2,4,5-T. The apph'cator,
using a mixture of 2,4-0 and 2,4,5-T, sprayed
approximately 80 acres of another 280-acre
private farm, making 10-11 passes over the
area; the spray left a white blanket. Wind
speed was 8-10 mph from the northwest. The
Complainant reported that on 8/28/71, his
farm, his family and himself were sprayed by
the helicopter near 12 p-ar. and overdraft oc-
curred for PS hr. The family members were ill
the following evening (8/29/71); approximately
2 years later the family stffl swelled of keto-
sfe, the children and wife's teeth crumbled and
all had joint pains and weakness. AH are quite
susceptible to illness. The cattle (holstein,
jersey, Guernsey, Charolais and Angus) and
pigs (mixed breed) showed symptoms by the
-------
Immediately after illness appeared and were
told the chemicals used for weed spray were
harmless to humans and animals. No examin-
ation was performed. - Hedical help for the
livestock was not sought until secondary
problems appeared. The cattle continued to
smell of ketosis also. From the time of the
spraying to the present, the family has experi-
enced personal health problems and their farm
animals have exhibited deformities. The
mother of the family has chronicled a record
of events and systematically has collected and
retained many biological specimens that relate
to the alleged over-spray. She had three
miscarriages between 7/73 - 6/77 with much
bleeding and required a blood transfusion after
the last one. The Brother had her teeth
extracted in fl/TS. Chronic illness developed
in the family including fatigue, insomnia, fre-
quent urination, loss of bladder control, ner-
vousness, restlessness, increased susceptibility
to colds and flu, fever, chiTIs and various skin
eruptions such as boils, pimples and sores. The
1-year-old female child began screaming the
day after the spraying and continued for 2
weeks. She had blood exuding from her nose
for 5 months after the spraying. She refused
to drink milk because it had an odor and was
"ropey." The 12-year-old son's face swelled
after the spraying and swells everytime he is
exposed to fumes of 2,4-0 and 2,4,5-T. The
father developed lung problems and eye irrita-
tion in 1972 after he entered a silo in which
forage from fields that had experienced pos-
sible overdraft had been ensiled. It is possible
that these effects were a manifestation of
farmer's lung or were due to silage gases
(volatile nitrogen oxides). Children bom to
neighbors since 1971 have had health problems.
In 1972, TOO chickens were acquired. Only 10-12
matured normally; the remainder died with
various ailments including curled toes, slipped
tendons of the hocks, paralysis and cancerous
.sores. In the spring of 1977 the family pur-
*chased TOO new Rock Cornish chickens which
were maintained indoors for 1H weeks, during
the next 2 weeks they were moved to a
portable, bottomless enclosure in the yard. At
the age of 5 weeks the chickens roamed the
yard during the daylight hours and were re-
turned to the enclosure overnight. From the
age of 1 month to 4 months, increasing num-
bers of the chickens developed leg abncrm all
-------
ties (SOS at 4 months). In TI/73 the famity had
a few crippled hens, one of which hatched six
chicks in the spring of 1978 that grew and
developed norm ally. The poultry laid soft eggs
with poor taste, color _and storage qualities.
Veterinarians who examined and autopsied
livestock from the farm reported no definite
observable deformities except animals with
stunted growth. An interviewer felt that the
signs and symptoms of the poultry and tive-
stock as described by the family were com.
patifale with multiple nutritional deficiencies.
A controlled study was planned to determine if
a soil residue from the 1971 spraying was
present 7 years later. No pattern of leg
deformities appeared obvious in three groups
of chickens raised under differing conditions
the first 4 weeks of their lives; about 10-15 X
showed one or more leg deformities. Vegeta-
tion samples taken on 9/8/71 across the road
from the family property tested positive for
2,4-0 and 2,4,5-T. In November (1978) soil and
water samples were collected from the farm-
for further laboratory analysis. The soil was
to be analyzed for 2,4-0f 2,4,5-T and dloxin,
the water for bacterial contamination and
nitrates. No 2,4-0 or 2,4,5-T was found in the
soil samples; dioxin results were not reported.
The bacteria in the water was 16+ and it was
declared unsafe for drinking. The family ran a
dairy farm and tree nursery (the trees in the
woodlot nursery were found in good condition);
the entire operation had been described as
•marginal." Sanitation procedures in the house
and bam were rather loose with a lot of
clutter and dirt. It was believed by some that
poor farm management and poor sanitation
have contributed to health problems on this
farm. On 8/22/74, the family brought a law-
suit against a member of the county board of
supervisors, the cousin who owned the woodlot
that was sprayed, the chemical company, the
applicator and the- application company. On
7/13/78 the lawsuit was dismissed by court for
failure to comply with procedures (failure to
pursue the case).

damaged plants (in a nursery/greenhouse)
stated that on the date of application a 29
mph wind was blowing from the sod farm
location toward her greenhouse resulting in
considerable drift to her location. She stated
the spraying f was done just south of her
property Tfne'approximately 50 feet from her
plant storage area. She asked the m an apply-
ing the chemicals to stop spraying under those
conditions and he refused. She called the
police, but they were also unable to get him to
stop spraying. She stated he sprayed again for
the next four days, 5/19-22. The owner of the
sod farm stated he was spraying 2,4-0 for
dandelions diluted at 1 gal/100 gal water. He
agreed on the direction the wind was blowing
but he said the speed was only 3 - 10 mph. He
stated he sprayed no closer than 400 - 500 feat
from the nursery and that he did no spraying
during the period of 5/19-22. The plants inside
and outside the greenhouse were inspected and
they definitely showed signs of damage from
pesticide poisoning; leaves and stems were
twisted and curled. There had been enough
2,4-0 drifting into the greenhouse through one

damage plants inside. The individual plants
sustained enough damage that the owner ter-

In an agricultural application a state game
management area was damaged after there
was aerial spray drift and overflight by a
commercial spray service. At 4:30 p.ra. on
5/31 the project manager for the area in
question observed a plane spraying near the
areas' reservoir and the pastures to the west
of it. We followed the progress of the aircraft
-with binoculars and watched as the plane over-
flew the pasture and sprayed reservoir
property while engaging in a turn before shut-
ting off his spray. The plane moved to another
area; the project manager followed and took
photographs of the plane overflying the reser-
voir with spray still bang released. Dam age to
fish and game lands was chiefly confined to
one area of the game lands at the northwest
corner of the reservoir. The damage was
confined to habitat destruction; no direct
losses of wildlife were observed or expected
because inspection of the flying service's
-------
inventory showed only containers of standard
herbicides. When the spraying occurred, it
was 74, there was a Tight breeze from the
north and no rain. Samples of water in the
overflight area and sprayed vegetation
samples were taken; the-results were not
reported. On 6/9 the area was visited to
survey the dam age caused by the overflights.
No drift was involved in the major damage,
although drift may have caused some of the
slight to moderate damage observed on the
periphery of the area. In the affected north-
west corner of the reservoir area, multiflora
rose and autumn olive were planted the pre-
vious spring. These were planted in two long
strips consisting of one row of rose, one of
olive in each strip. Damage was as follows:
southwest planting, 65 muftiflcra -all affected
by chemical damage; 45 autumn olive - all
affected by chemical damage except 3 plants;
northeast planting, 34 multiflora - all affected
by chemical damage except one plant; 47
autumn olive - all affected by chemical
damage. The damages ranged all the way
from "slight leaf curl and coloration change to
complete defoliation. It was easy to deter-
mine and distinguish planting mortality from
2,4-0 damage, since those plants suffering
from planting mortality were bare stems with
no leaves present on the ground (they had died
much earlier). The plants had not been
stressed by drought of summer and conse-
quently those that survived planting (the vast
majority did) were in good shape at this time
(immediately prior to the spraying incident).
It was still too early to assess permanent
damage. The next spring would allow such
determination. It was considered that even if
there is not widespread plant mortality, the
plants have been severely stressed; m any have
-lost a growing season, and it was suggested
that replanting be done in the area since the
plantings would have many holes in them due
to mortality. Roughly 1% acres of mature
cover was ruined for at least one year with
extensive defoliation and possible mortality to
locust, sumac, dogwood, walnut, and forts
such as dock, ragweed, etc. These forts were
the main wildlife food in the area (seed
production). Another six to eight acres sus-
tained lesser damage to forts, probably as a
result of drift from this same spray activity.
While not all cover was destroyed,
-------
considerable food production potential was
lost (fort damage). This area was to the north
and east of the m ain dam age between the rows
of planted shrubs m entioned above and further
northeast. The damage to potential wildlife
populations could possibly.be estimated as:
loss of cover for one covey of quail for this
year and a delay of a year in establishing
perhaps two or three coveys as a result of loss
of the plantings. More loss would result if the
nature cover was kitted instead of damaged
(can only be determined later). Dove food and
nesting cover were definitely lost in the same
manner as for quail, and rabbtts were similarly
effected.

A project manager at a state game manage-

"5/20/72. Spray drift was observed falling on
foliage within the preserve. The manager
recorded the plane's description and number;
further checking determined that the chemical
used was 2,4-0 in low volatile ester form. The
• ajar area of damage contained about 20 - 25
acres of bottomland crop-producing area with
a double row of multiflora rose, plus about an
equal amount of non-cropland along the hill-
side. The damaged area was visited en 7/3 and
7/26. Typical herbicide damage symptoms
were observed: curled leaves, curled plant
terminals, non-seasonally induced color
-------
changes, etc. Damaged plants included:
snowberry, coralberry, currant, milkweeds,
skunkbrush, sweetclover, sumac (smooth),
goatsbeard,roughleaf dogwood, American elm,
cocklebur, freemont leatherleaf, butterfly-
weed, sagewort, prairie rose, hackberry,
various wild thistles, burr o'a'k, American plum,
blackberry, gooseberry, and Virginia creeper.
These were on the hillside. Additionally, there
was injury and mortality to roughly 1/8 rafle of
mature, double-row multiflora rose hedge
which runs through the middle of the culti-
vated land. There was no observed damage or
apparent direct mortality to wildlife in this
area. As is the situation in this kind of
problem, there is no way to really assess the
damage which occurred, either to plants or
wildlife (indirect damage caused by habitat
destruction). There was undoubtedly a loss of
cover and seed production on the hillside, but
some cover did still remain there. It was
considered to be an ideal hillside, covered with
a desirable interspersion of brushy clumps and
grassy, fort covered pasture. The species of
wildlife involved or potentially affected were:
quails, pheasants, rabbits, and doves, with pos-
sible indirect loss to other game species, plus

In a park/recreational area-related incident, a
22-year-old employee was hospitalized after
an exposure to 2,4-0. He was Involved in
spraying the chtmical for leafy spurge control
in a game management area on 7/5 and 7/7.
He was wearing a disposable white filter mask*
plastic goggles, baseoaH cap, a work-supplied
uniform, elbow-length rubber gloves, and para-
chute type leather boots. In the application
the wind had been blowing the spray back into
his face. Application of the chemical was
from a TOO-gaflon tank (jeep mounted) at the
rate of 2H gal/100 gal water. About 600 - 700
gallons had been required for this job. The
weather during application was pleasant with
temperatures ranging from 70 -60 F. The
subject also had spilled a dilute solution down
one trouser leg. The individual felt fine when
he arrived home from work on 7/7. He
showered and lay down. One-half hour later
he was drowsy and lacked an appetite. He did
not eat and went to bed at 8:30 p.m. He
visited a physician the morning of 7/8 after
experiencing nausea, drowsiness, diarrhea and
excessive vomiting every one or txo hours
beginning at 2 a.m. on 7/8, He did not tell
the physician about his involvement with pest-
icide spraying and was diagnosed as having
influenza and was treated for same. The
subject did not respond to treatment and came
to the physician again the following day, 7/9.
Further questioning at this tira e revealed his
-------
work with pesticides, and the physician in> me-
diately began treatment with atropine sutfate
at a rate of V50 grain every six hours; the

Volatilization and drift occurred when a herbi-
cide was used by a city to control blackberries
1n a workshop area. An examination of a home
yard and garden area of a complainant showed
that the area had been exposed to a growth
regulator herbicide. Symptoraology Included
abnormal leaf cell development, retarded
growth, curling of sterns and partial curling of
leaves. Showing minor damage were trees
(grand fir, elderberry, cherry, Douglas fir,
willow) and a shrub (Deutzia). Showing minor
to medium damage were nasturtiums and a
hazel wood tree. Medium damage was noted in
a dogwood tree, TO rose bushes, 2 hawthorn
trees, and 2 devil walking cane plants. Two
varieties of grapes were seriously damaged.
The vines were expected to live; production
would be seriously impaired. Tomato plants
and squash had to be replanted. A loss claim
was filed in the incident.

In an agricultural incident a farmer applied a
herbicide to his barley crop1 in May; the barley
was of the right size and the time of applica-
tion was correct. To 75 acres he applied 2,4-0
(a nine) by Itself, then for the next 600 acres
he applied 2,4-0 (acid/ester) and 2,4-0 (amine)
•ixed at H pt each/5 gal w^tsr/scr*. at the
end of the season he sprayed 51 acres with a
mixture of 2,4-0 (amine) and 2,4-0 (acid/-
estar), which he mixed in a proportion that he
stated may have been more than 50% 2,4-0
(araine). The first 75 acres were not damaged;
nor were the last 51 acres. The 600-acre area
developed injury which appeared to the farmer
to be chemical damage. The farmer stated
that the 2,4-0 (acid/ester) used in the last
application was from a container with a dif-
ferent code number from the 2,4-0 (acid/-
ester) which had been used in the 600-acre
application. He attributed the damage to the
particular batch of 2,4-0 (acid/ester) used on
the 600 acres. The damaged barley from the
600-acre area was analyzed by a plant path-
ologist, and the causative factor was said to
be 2,4-0; however, it was felt many factors
could have caused the damage, such as time of
application, temperature or humidity during
application, or defective chemicals. The dam-
aged acreage was treated with a combination
of pesticides not recommended by label data
on either product but considered 'common
agricultural practice not constituting misuse-"
Tests were done to determine if 2,4-0 (acid/-
ester) from the suspect batch was contami-
nated; these tests proved negative. The other
batch of 2,4-0 (acid/ester) and the amine
product were unavailable for sampling. It was
felt that the yield from the damaged cropland
would be 15 to 255 less than normal. The
herbicide dealer suspected that the acid/ester
product had been applied too early.

mother was a spina Bifida patient with severe
hyphoscallosis and a severe history of respira-
tory problems and asthma. She was confined
to a wheelchair and had moved frequently
from urban to rural areas in search of less air
pollution. She also had a history of extreme
sensitivity to petro-chemicals (especially
those related to sutfide fumes, hydrocarbon
type chemicals). Her sensitivity was recorded
as probably a neurological disorder resulting
from her general status of autonomic dysfunc-
tion. The daughter (age unknown) became
semi-conscious at a church camp when she was
acutely exposed ta an aerosol bomb-type
pesticide. Her present sensitivity to numerous
pesticides, possible allergy, for which she had
been treated may have stemmed from the
camp exposure. Both of these individuals wers
hospitalized and treated symptomaticany
after they experienced extreme respiratcry/-
allergenic symptoms following a U.S. forest
spray program with the pesticides 12 to 14
miles from their residence. The physician felt
it was due to drift. In addition, highway
spraying by a road crew near the residencs
also caused violent symptoms. Cholinesterase

just visible, and further abnormal plant growth
was not expected. A medium injury symptom
indicated that the foliar and stem growth was

occur and that a period of time would be re-
quired before the herbicide dissipated. It was
felt that none of these plants or trees would

In an agricultural Incident a farmer com-
plained that his potato crop was damaged by
pesticide drift. He expected 60S of his crop
to be lost due to this contamination. The
plants appeared to have been subjected to
some sort of stress condition; there was no
evidence on the potato plants themselves
which would have indicated damage from
phenoxy herbicides. Ncrgold Russets, Norland
Red and FL-96 potato fields had a similar
appearance. M any older leaves near the base
of the plant had a definite yellow color and
leaf margins were rolled up and in. The
foliage on pie a elons in these fields exhibited
typical 2,4-0 symptoms on only one leaf in
most instances; it was about the third to fifth
leaf fro m the tip of the vine. The veins of the
leaf were enlongated and abnormally close
together. Indentations on the palmately lobed
leaves were deeper than on normal leaves.
Lasota potato vines were larger, mere
vigorous with a deeper green color, tubers
were larger and more numerous. Pie melons
were not noted in this field. A number of
other plants in a garden in the immediate
vicinity such as bell peppers, pinto beans,
tomatoes and pie melon did exhibit symptoms
of damage similar to phenoxy herbicide dam-
age such as deformed leaves, parallel leaf
venation, and epinasty. None of these plants
were dead and no dead soots were observed en
any of their leaves. The owner was quite
certain that the damage to his crop was a
result of spray dnft from an application to
pastureland to the northeast of his property.
It should be noted that the distance between
his potato field and this pasture is 2 miles at
the nearest point. The owner of a flying
service stated that he did treat the pasture
area with 2,4-0 amine on 4/23/74 and that
winds were northeast at 0-4 knots. Weather
service reports indicate that winds were net
more than 10 knots that day. There was no
visible evidence of actual phenoxy herbicide
damage to the potato plants in any of the
fields observed. According to available
inform ation, the potato plant is mcrs resistant
to 2,4-0 herbicide than the average
-------
herbaceous plant; for damage which would
have been significant enough to give a
reduction in crop yield, the plants should have
exhibited some symptoms of damage as that
observed on the more susceptible plants in the
area. The only exception to the above which
could have had an effect on the yield would
have been for the herbicide to have reached
the plants when they were in full bloom. A
state representative stated that the potatoes
were in bloom on 5/14 when he inspected them;
the potato farmer was not questioned on this
point. The 100 acres of potatoes were planted
3/10 - 20/74. The land was fertilized in
February with 100 pounds per acre 0-0-50
(potash) and at planting wtth 500 pounds per
acre 5-10-5; it. was top-dressed on 5/3 cr 5/4
with 150 pounds per acre 335 nftrcgen
fertilizer. Other chemical applications were
made on 5/2 and consisted of 1H pint/acre
captafol fungicide and 1 pint/acre diazinon
insecticide. A state investigator had walked
the entire distance between the two locations
and what appeared to be indications of 2,4-0
damage were noted on plants for the enrire
distance, although this damage was extremely
obscure in most instances. Eighteen days
elapsed from the time 2,4-0 was applied to
the pastureland until the first report of
damage. In the meantime, another aerial
applicator had applied fungicide and insecti-
cide to the potato crop on 5/2. It would be
difficult to rule out the possibility cf herbicide
contamination from this source. Damage was
, first reported to state officials on 5/8. The
report of a plant diagnostic lab indicated that
three different plant diseases caused by fungi
were identified from five of the plant saeci-
. m ens submitted by state inspectors, namely
stem rot, Fusarium wilt (plants showed vas
cular discoloration and early blignt (plant
showed a browning cf leaves). A pesticide lab
failed to recover any residues of phencxy
herbicides, picloram and dicamba from potato
plant samples collected.

Epinasty was readily observed in the peas
extending from the western edge of the field
to approximately one-half the wioth (E-W) of
the field in the southern section and across the
full width of ttie northern section. Total
acreage of the field was <*4 acres, of which an
estimated 25 - 30 acres apoeared to be

covered a 50-foot swath marked with an auto-
matic flagger and he flew 3 feet above the
ground when applying chemicals. Spray
nozzles were of both T-jet and fan type,
-------
spaced 12 inches apart, and the boom pressure
was 14 pounds for this job. The pilot indicated

exposure .to a growth regulator herbicide which
was most evident on the west side of the trees.
The yield loss was restricted to the west portion
of the fruit trees and they did not die. Fruit
bud set for the 1975 crop was not adversely affec-
ted by the 2,4-0 exposure. Minor injury symptoms
were noted on two willow trees, lilac bushes,
and a spirea bush. Several flower species exhibited
minor symptoms. A 15-year-old grass-alfalfa field
located west of the highway showed 2,4-0
symptoms. It was estimated that approximately
20-25 acres of the alfalfa-grass pasture
exhibited these symptoms. Those plants growing
near the south fence were yellow and exhibited a
twisting and curling of the stems. No new
growth was observed on alfalfa plants. Possible
death of some of the alfalfa plants was expected
to occur within 50 feet of the south dence.

A sugar beet crop was damaged by chemical
spray drift from an application to nearby
fields. Ten acres of 63 acres of sugar beets
were damaged. Whole plants were taken as
samples at approximately 50-foot intervals
along a northeast-southwest diagonal through
the damaged area. These samples were found
to contain 3.31 ppm 2,4-0. The sugar beet
owner recalled seeing a spray plane applying
chemical to the property directly east of the
beet field. The two fields were separated by a
25-foot-wide dirt road. The flying service was
contacted and said that they had used 2,4-0
(amine), 4 Ib acid/gal of material, at a rate of
2 pt/acre to spray grain on 6/3 and 5/10. The
area adjacent to the beet field was sprayed on
6/10. The plane was equipped with automatic
flagger; the booms had 36 nozzles with 3-10
orifices and the pressure at the nozzles was
always 20 PSL All nozzles had a check valve
diaphragm to prevent dripping. The tank truck
driver was instructed to check for leaks each
time the plane was loaded with chemical. The
pilot flew in east-west and west-east swatns,
carrying him over the beet field. He flew
approximately 5 feet above the grain while
spraying but stated he was 150 -200 feet above
the beet field. Winds were calm to 3 mph,
temperatures were 52 - 54°F. The pilot felt
• he had taken adequate precaution to prevent
any drift going onto the beet field. On 6/24
the weeds between the grain and beet field
were examined and appeared not to have been
'affected by 2,4-0. On the north side between
the beet field and a 40-acre corn field,
broadleaf weeds showed typical signs of 2,4-0
damage. The owner of this corn field was
contacted and he stated his son had used a
puTJ-type spray rig on approximately 6/10 to
apply 2,4-0 to his corn crop. He sprayed the
west portion of the field in the morning and
the east in the late afternoon. He used 2,4-0
-------
(araine), 4 Ib -acid/gal material, and the
sprayer was pulled at 5 mph with 30 PSI
pressure. The spray booms were 32 Inches
above the ground and the son noticed no wind
while spraying. From the damage pattern in
the beet field, it would appear that the drift
had come from the aerial application of 2,4-0
to the grain, but there was no visible damage
to broadleaf plants between the two fields.
While damage to broadleaf plants could be
followed from the com field to the border of
the beet field, the pattern was atypical for
drift from this direction. It was impossible to
determine the responsibility for the dam age.

which appeared 2 days after spraying, was
spotty with a 13Vacre sugar beet field east of
the wheat sustaining the most damage.
Epinasty was noted throughout this field and in
an other fields, with the exception of a 5-acre

An electric power cooperative arranged for
'right-cf-way spraying with an out-of-state air
service which used a helicopter with a sta-
tionary spray rig. The herbicide was apolied
at the rate of 2H gal/acre. One of the small
organic farm owners (40 acres) along the
right-of-way was of the opinion (8/6/74 phone
conversation) that herbicide misuse occurred
in the spraying. He stated that his pond as
well as several others are the residents' main
water supply, and he was fearful that spray
-------
had contaminated the streams. Laboratory
tests of soil and vegetation samples taken
8/7/74 (7 days after spraying) from under the
power tine showed 2,4-0 and 2,4,5-T. There
was no chemical evidence of the herbicides in
his pond. The herbicides could not be detected
chemically on the crops out the vegetation did
show typical phenoxy-type damage. During a
visit to the farms and through the adjacent
national forest, there was little, if any, sign of
over-spray or deviation from the right-of-way.
There was some minor wilting of trees, and
crops in the area appeared to be damaged.
Further investigation showed that the power
fine passed through cattle grazing area,
streams crossed the right-of-way, and run-off
would be unavoidable in some areas. The
spraying operations had fae«n performed
competently; it was suggested that the farm
owners and the power company discuss future
maintenance practices to insure avoiding con-
tamination of the streams and ponds (especial-
ly with continued run-off) and the grazing
pastures and ta avoid severe drift damage.
More than one method of clearing the rigttt-
of-way might have had to be employed. It was
concluded.that the product should not be ap-
plied along areas of the rights-way which
were doss to grazing pastures or streams.

In an industrial incident, 16,550 gallons of 2*4-

period from 8/13 - 16/74. The 2,4-Q escaped
from a 30,000-gallon tank in a chemical
co'mpany formulating plant. The tank con-
tained 4 pounds per gallon 2,4-0 (amine)
formulation. The tank had a 1-inch drain pipe
with a pressure relief valve Incorporated in
the discharge service. Someone attached a
hose to this pipe, which was in an obscure
area, and the pressure rtttef valve malfunc-
-------
tioned, allowing the material to drain from the
tank. The floor drains in the plant were
designed to require a manual release of
accumulated fluids as a safety factor. The
floor drain involved in this, accident was not
properly closed, allowing the chemical to flow
into the sanitary sewer and from there to the
sewer plant and a major river. Samples were
taken at the plant, the river, and downstream
as wen. No 2,4-0 was found in any of the 20
samples taken. It was felt, by a chemical
company representative, that the movement
of the chemical through the sewer would have
the effect of lowering the percent of active
ingredients since 2,4-0 is affected materially
very quickly by bacterial action, plus the fact
that much of the material would be removed
with the sludge which 1s retained in the sludge
pit.

Mater. A fish and game department was
notified. By S p.«., the stream had turned
milky and .dying fish (young salmon} were in
evidence. Some children waded in the stream
picking up fish and thus were exposed to the
chemicals* A water sample was taken at 3
p.m. about 200 yards downstream from the
bridge on which the truck had stopped; labora-
tory analysis of the water showed 7.9 pptn
2,4-0 and 5.3 ppm 2,4,5-T. The following day
at noon, fish and water game personnel took a
water sample from a pool of cloudy water in a
depression in the bottom of the stream under
the bridge. In collecting the samples, the
individuals experienced burning sensations on
their skin (thought to be caused by the
emulsifier residues). Analysis of the sample
showed it contained 245 ppfl 2,4-0 and 232
ppm 2,4,5-T. At 6 p.m. on the same day, an
agriculture department officer sampled watsr
30 feet downstream and 50 feet upstream

killed in the stretch of stream extending about
H mile downstream from the bridge. Most of
the fish were fingerlings. The stream was
used as a domestic water supply by two area
residents. One of these pumped contaminated
water through his system prior to his being
made aware of the spiTJ. There existed the
possibility that afl pipes would have to be

Grazing pastures at a dairy farm were aerially
sprayed with herbicide on the morning of 4/5.
According to the dairy farm supervisor, a 10 -
12 mph wind was blowing from the west-
northwest when two planes sprayed herbicide
at a rate of 1 pint/10 or 20 gal water/acre.
Measures taken to reduce the possibility of
spray drift included an anti-drift additive in
the spray mix and the use of flagmen to
indicate flight lines and cut-off points; pilots
were instructed to leave a 300-yard untreated
margin within the farm borders. Three
farmers n'ving adjacent to the sprayed area
reported damage to home and commercial
vegetable gardens beginning 1 - Z weeks after
the spraying. ATI three farmers reported that
the spray planes flew over their land at times;
only in o'ne case did the planes fly directly
over the areas which later displayed damage,
None of the farmers reported seeing spray
released from the planes while flying over
their lands. Plant damage included curling or
drawing up of young leaves and shoots of
vegetable plants, blackberries, trees, and
weeds. AH three farmers stated that they
expected to lose most of the vegetables from
damaged gardens and fields. Losses had
occurred the previous year when aerial appli-
cators directly sprayed gardens and fields on
the three farms while treating the same dairy
farw. A state extension official examined pea
and tomato samples submitted on 4/23, and
identified phenaxy herbicide damage charac-
terized by strap leaves and parallel veins. On

Aerial applicators sprayed grain fields on two

2,4-0/acre, diluted with water (foam was also
used). The applicator's records indicated that
the wind was calm. Label instructions were
reported to have been followed during applica-
tion. A neighbor reported that a slight breeze
caused spray to drift across the road onto his
70-acre potato crop. He stated that growth
ceased and that leaves turned yellow and
curled; the crop rem ained in this condition for
approximately 3 weeks. Due to the damage
and to a "late spring," the fanner expected
total loss of yield. The potato field was In-
spected and/or plant samples were examined
by several agricultural experts during the
period of 7/14-2L. Ortft from 2,4-0 was
determined to have passed over the affected
property, as evidenced by browning and dessi-
cation on the east side of several trees. Herbi-
cide symptoms were identified on volunteer
potato plants which had emerged from thje
previous year's tubers; these effects were pre-
sumed to be due to a prior herbicide applica-
tion in 1974. No 2,4-0 effects were found on
1975-planted potatoes, although all plants dis-
played damage. The damage was attributed to
a stress condition involving late planting
weather conditions, lack of irrigation, lack of
nitrogen fertilizer, overgrowth of weeds, and
failure to rotate crops. A 60* loss of yield
was predicted. Some inspectors reported hav-
ing seen similar symptoms in other fields
throughout the area; in these cases, no cause
of damage could be determined although
-------
herbicide exposure was ruled out. The owner
of the treated grain fields stated that the
neighbor's potato plants, had not yet emerged
at the time of application; lack of herbicide
symptoms on the 1975 plants seemed to
support this statement.

A 20-year-old city maintenance employee was
spraying highway medians with a hand sprayer
(4-6 tsp/1,000 sq ft). He sprayed for
approximately 2 hours wearing protective
gear, including waterproof clothing and a res-
pirator, which were not required by the
product label. The following morning a slight

days later. The tongue was coated with a thick
membrane and the pharynx had a thick coating
of dried mucoid material. While hospitalized,
he was treated with antibiotics in view of the
presence of coagulase positive staphylococci
in a culture. The reaction of the tongue and
floor of the mouth proceeded to the point of
necrosis involving the anterior one-third to

herbicide application to an adjacsnt maize
field. According to a veterinary report on
6/17, a "fair amount* of wind was blowing,
carrying spray drift onto a field in which over
100 cattle were pastured. Noxious weeds in
the pasture included fireweed, silver leaf
nightshade, and cocklebur (the latter two in
the thorny stage). Three cows expired on 6/15,
one on 6/16, and one on 6/17. At the time of
the veterinary report, 20 cattle were reported
.to be stiTI affected with emaciation, dyspnea,
diarrhea, and pronounced cyanosis. A field
diagnosis of acute nitrate toxicfty was made.
A quantttatived nitrate test was requested. A
level of 3,560 ppm nitrates in fire weeds grow-
ing near the farmhouse was reported on 5/18;
this was considered a "dangerous* level. Pas-
ture vegetation contained 730 ppm. On the
basis of a negative ONP (Diphenylamine blue)
test on ocular fluid from a cow, it was con
-------
sidered unlikely that the arrim al died of nitrate
poisoning. A necropsy on the cow indicated
lesions and changes not indicative of any par-
ticular condition; pulmonary emphysema was
present, suggesting the possibility of solanum
(nightshade) poisoning. Nitrate tests results
reported on 5/22 revealed 540 ppm and 820
ppra in rumen contents of two cows, 3,390 ppm
in pasture weeds, and 31,760 ppm in weeds
near the farmhouse. Three more cattle were
reported dead by 6/18. Necropsy on a second
animal yielded results similar to the previous
necropsy. Solanum poisoning was suspected,
and it was also stated that the lung lesions
could possibly be due to inhalation of a noxious
substance. It could not be determined if pesti-
cide was the cause of death.

The damage was on the side of the row facing
the fence. Tips and branches on conifers
farther down the right-of-way on other resi-

Berries had been picked and made into jelly

A spill occurred at a chemical plant some time
after the end of the workday on 1/30/78 and
7:30 a.m. on 1/31/78. The plant had been
transferring 10,444 gallons of 68.3* 2,4-0
from a rail car to an underground tank with a
capacity of 10,000 gallons. Either a valve on
the rail car was left open or it was opened
sometime during the night by parties unknown.
The plant supervisor stated that there were
two underground tanks with the same capacity
but only one was being used at the time of
transfer. He also stated it took approximately
4-5 hours to complete a transfer. The
supervisor further stated that the watchman
had sworn he turned off and properly secured
aTl the necessary valves before leaving the
area. The spilled herbicide contaminated the
soil around the car area and that from the
tank car to a drainage pipe. The pipe ran
approximately 250 feet and emptied into a
rock and red rock base on the bank of a creek.
This resulted in the spilled herbicide contami-
nating the creek bank (approxim ately 400 gal-
lons of the material spifled). The chemical was
insoluble in .water and had a specific gravity of
1.228 (at 20°C) which made it sink. The water
level was lowered in the canal by 2h feet to
make it easier to clean up. A cleanup was
initiated by the chemical plant. The Coast
-------
Guard, the state fish and game authorities and
the local water quality board became involved
and monitored the decontamination. Between
1/31/78 and 2/6/78, the following was accom-
plished: 1} pumped and mopped up in the area
below the drainage pipe; 2} removed the con-
taminated mud and soil in area of creek
bottom and 3} replaced base and rock on creek
bank. A total of 560 cubic yards of rock, soil
and mud was removed. A total of 16,000 gallons
of contaminated water was pumped and
removed. The cost of the whole operation was
approximately $37,500. An additional cost of
$6,200 was charged by the local county water
district for water lost to replenish their

stated that it appeared that the helicopter had
not come any closer than approximately 1,500
feet from the private lands (they tried to
maintain a L;500 - 1,800 feet buffer zone
around the spray area). Residents reported
smelling the diesel oil, and some had heard the
helicopter. Five water samples from five
different sites on one resident's property were
taken for analysis at different times on
2/17/78. The following results for 2,4-0 in

Six people had symptoms including headaches,

other people had complaints 24 - 43 hours
later. Fire fighters, who wore setf-contained
breathing apparatus and skin covering, were

used respiratory protection, ATI but one re-
covered completely within 24 hours. Cholines-

pounds of pesticide active ingredients in the
store's inventory, approximately 20% had been
sold before the fire, leaving approximately 530
pounds of active ingredients in the store at the
tine of the fire. An estimated 9 pounds of
chlcrdane were unaccounted for after the fire,
and were presumed to have been consumed in
the fire or washed into a stream. A stream and
lake adjacent to the store were contaminated

A number of residents were concerned about
chemicals applied for weed control at the
school their children attended. Investigation of
the incident revealed that some excess, un-
wanted floor finishing (wax) had been applied
to some weeds as a means of disposing of the
compound. The school custodians had been
-------
dissatisfied with the wax, and the company,
not wanting to pay return freight charges on a
35-gallon drum of wax, suggested that it might
prove effective in retarding weed growth. In
addition to the floor wax, the custodians, on or
about 5/1/78, applied herbicides in two areas
on the school grounds; in one location a ready-
to-use herbicide was used and in the other
area a concentrate without dilution. The
containers had been disposed of by 5/17/78,
and it was unknown what type of herbicides
had been applied. Vegetation and soil samples
were analyzed obtaining the following results
(ppm 2,4-0): 1) kindergarten area, vegetation

A family found it necessary to leave their
home overnight due to drift from an applica-
tion of the herbicides. The application was
made by a department of natural resources to
-------
control brush. The family received a written
notice on 5/15 that the application would be
made 1n late May or early June; the applica-
tion was wade on 5/18 (H to h mile from the
house). The applicator did not can the resi-
dents, post signs, or in any way make the
residents of the area aware that spraying was
to be done. The drift formed visibly and set-
tled in the valley. Relatively dry and warm air
in the evening of 5AS cooled off significantly
after mixing with the chemical-wata* solution.
With the additional downwash of a helicopter,
3 substantial mass of air with spray mist sank
along a 20 to 50 slope to the bottom of the
valley, which filled completely to the entry
road to the residential area. One family had
house windows open and fumes entered the
house, making it necessary for the entire fam-
ily to leave the house at midnight. A physician
found that the mother had developed an irri-
tated nasal mucous membrane and a red throat
and the father had slight nasal congestion
after the'exposure to the drift. The major
portion of the sprayed 40 acrts was drained by
a small stream which flowed (2 gal/sec in the
wet season) eventually into a river. The
stream water was used for domestic purposes
at various farms in the vaTJey% Tests of water
samples indicated there were no residues in
the water. The water and foliage samples were
analyzed by both the USD A and the Depart-
ment of Natural Resources; samples were
taken by the USD A on 5/2, by the D N R on 6/1.

A .woman concerned about health effects and
whether crops from the area were edible con-
tacted (6/27/79) a state department of agri-
culture to report a drift of the chemicals. An
investigator was on the scene on 6/29/79. Her
property had the most severe damage (defoli-
ated trees and loss of a home garden) of any of
the affected properties. A sample from a
hibiscus tree was collected and analyzed. Re-
sults were Ul ppm 2,4-0 and 0.1 ppm 2,4,5-
T. An agriculture inspector could detect no
drift pattern which would reveal the source of
the herbicides. The woman alleged that there
were three sources of herbicides: (1) the city
herbicide applications, (2) a spray tank kept
behind the city hall and (3) a disposal site
behind the city hall for the herbicides used in
1975. She stated she lived in a straight line
from the cfty haTI and that a city councilman
along with her had detected damage between
the city haTI and her home. Accenting to the
woman, the neighbors had diarrhea and nausea

A person from a physician's office reported
that a woman had reported that her family and
other persons in her neighborhood had experi-
enced illnesses which were believed to be
associated with the applications of agricul-
tural chemicals to sugar cane growing around
their homes. These events had been occurring
and recurring for more than a year and were
related to the growing of the crop. The ill-
nesses were present during three periods: (!)
at the time of application of the.chemicals, (2)
when the soil in the field was being turned and
(3) when the cane was being burned prior to
harvest (homes were downwind of the crops).
The latter period seemed to produce the most
serious effects. The woman remarked that
there was no apparent misuse of the
chemicals. Her husband (a patholougist) agreed
and believed that the problem was serious.
Illnesses reported were (1) a swollen, sore
throat that lingered on, (2) persistent asthma-
like symptoms and (3) cuts and scratches that
would not heal. None of these maladies re-
sponded to antibiotics. A follow-up call on
1/2/80 revealed that the woman believed the
problem still existed but seemingly to a lesser
degree as her family did not react as seriously
as they had the previous fan. The number of
people exposed or affected had not been de-
