Major Routes of Exposure: Der .l, ocular, and ingestion
Physiological arid Biochamica.l Behavioral Character’tstics:
liar absorption: Not applicable - fluchioralin is soil-incorporated.
Trans 1.ocat ion: Residues are taken up and translocated through t roots
and shoots of cotton and soybean plants. Parent c poi. d
and sa metabolites have been identified in cotton arid
soybean fo11 e following exposure of the roots to
fluchlor’al.tn
Mechaniam of pesticidal action: Believed to affect seed germination and
other physiological growth processes.
Metaboliam and persistence in plants and ari1rr 1 : Plant metaboli is riot
adequately understood. Pluchloralin residues did not
transfer to rtm inant tissues at exaggerated rates (67X the
expected intake by beef cattle). Degradation in an 1 n l s
is step-wise through N-dealI ].at ion and N-hydrolysis.
&ivirormental Q aracteristics:
Adsorption and leaching in basic soil types: Pluchioralin (unaged) and
fluchioralin residues (aged 30 days) are relatively 1 n bile to slightly
mobile in loamy sand and sandy soils, but the degradate 2,6-dinitro- 1 -
trfluor ethylphanol is highly mobile in lo sand soil and mobile in
sandly clay loam soil. Pluchioralin is slightly mobile in runoff fr
plots (5—12% slope) of silt loam soil.
Microbial breakdown: No data

fact sheet
L083 fran photodecanposition and/or volatilization: Fluchioralin
photodegracles rapidly (half—life 27 minutes) in ater (pH 5.6) when
exposed to artificial sunlight. Photodegradation of solid tluchloralin
film is slower (half—life 48 hours in artificial sunlight). b valid
volatilization data are available.
Bioacc ulation: No valid data
Resultant average persistance: Half-life ranges fran <32 to 120 days,
depending on soil type.
Half-life in Water: Stable in water over pH range fran 5.0 to 9.0, if riot
exposed to light.
Ecological characteristics:
Hazards to Birds: ta gap
Hazards to P uatic Invertebrates: 1 ta gap
Hazards to Fish: High toxicity poses potential threat to fish populations.
Hazard cannot be evaluated t itil receipt of certain
enviro ir ntal fate data.
Potential Probl s with E dangered Species: USD1 has nmde a Jeopardy

4• Stzrary of Regulatory Position and Rationale:
Use Classification: Not classified.
Use, Formulation or Geographic Restrictions: Manufacturing-use products
my only be formulated into end-use products intended for use as an
herbicide on dry and succulent peas and beans, cotton, okra, peanuts,
soybeans, and stgiflowers.
Unique Label warning stat nts:
a) Use Pattern Stat nprita :
Labels of manufacturing-use products must bear the statement:
“For formulation into end-use herbicide products intended only for
use on kIdney, 1 1i’ , navy, green, pinto, Great Northern or edible
soy beans, blackeyed, cow, field, or garden peas, cotton, okra,
peanuts, or swif1o rs.”
b) Precautionary Stat ita :
Labels of manufacturing-use products must bear the statanent:
“1 not discharge effluent containing this product into lakes,
streams, ponds, estuaries, oceans, or piblic waters w iless this
product is specifically identified and addressed in a NP S
