I. EXECUTIVE SUMMARY:

Tagetes oil is a new biochemical pesticide active ingredient intended for use as an
insecticide/acaricide for the control of mites, whiteflies, aphids, thrips, mealybugs, scales, and
pyslla on a variety of food crops. The active ingredient is extracted from the flowering herb,
Tagetes minuta (Muster John Henry or Mexican Marigold). The major constituents of the
identified components of tagetes oil are terpenes, which are found in a variety of essential oils.
Tagetes oil, as TagetespatulaL., T. erectaL., or T. minuta L. (T. glandulifera Schrank), is
approved by the U.S. Food and Drug Administration (FDA) for use in food as a natural flavoring
substance and natural adjuvant (in the oil form only) under 21 CFR 172.510. Tagetes oil is also
used in some cosmetics including shampoos, soaps and lotions (EWG, 2010).

The Biopesticides and Pollution Prevention Division (BPPD) determined that the
data/information submitted for product chemistry and Tier I acute toxicity for tagetes oil satisfy
the current guideline requirements. Acceptable scientific rationales were submitted for the
subchronic [90-day oral (OCSPP 870.3100) and 90-day inhalation (OCSPP 870.3465)],
developmental (OCSPP 870.3700), and mutagenicity data requirements [in vitro mammalian cell
assay (OCSPP 870.5300 and 5375)] in lieu of data. BPPD determined that the rationales
submitted were acceptable based on tagetes oil's toxicological and exposure profiles. Significant
exposure to humans is not anticipated for tagetes oil based on low application rates, appropriate
Personal Protective Equipment (PPE) requirements on the product label, and rapid degradation in
the environment. BPPD granted a waiver from conducting a 90-day dermal study (OCSPP
870.3250) based on the rapid volatilization of the active ingredient and because prolonged
dermal exposure is not expected (the product is not purposely applied to the skin and
handlers/applicators are required to wear appropriate PPE). BPPD received data for the
mutagencity data requirement [Ames test (OCSPP 870.5100)], which indicated that tagetes oil
was not mutagenic with or without metabolic activation. Although the data requirements were
satisfied for the new active ingredient, tagetes oil, BPPD notes that should future intended end-
use product (EP) applications result in different anticipated exposures to humans, these data
requirements may need to be readdressed.

For nontarget organisms and environmental fate data requirements (OCSPP 850.1010 to
850.4450), the applicant either submitted acceptable data/information for the EPs or the data
were waived because the guideline study was not applicable. BPPD granted a request to bridge
the data from the EPs to the active ingredient, tagetes oil, because the applicant indicated that the
active ingredients in the EPs act synergistically; thus, the combination of these chemicals is more
potent as an insecticide than each active ingredient alone. Therefore, the toxicological profile of
the EPs is more relevant to the risk assessment than the toxicological profile of tagetes oil alone.
Based on the nontarget organism data from the EPs, which indicated that the EPs were
practically nontoxic, and the screening level risk assessment, the Agency determined that
registered use of tagetes oil in the EPs should not result in adverse effects to birds, fish, aquatic
invertebrates, plants, or nontarget insects.

Based on the acute toxicity data for tagetes oil, the active ingredient is toxicity category III. EPA
has not identified any toxic endpoints for nontarget mammals, birds, plants, aquatic, or soil
organisms. EPA has no concerns for any nontarget organisms exposed to tagetes oil when used


-------

in accordance with approved label directions. Given that tagetes oil has very low toxicity and
presents little, if any, risk to nontarget organisms, EPA has concluded that it is in the best
interests of the public to issue the registration for the EPs, Bug Oil Food Use (EPA File Symbol
No. 85937-E) and Bug Oil Ornamental (EPA File Symbol No. 85937-R), which contain this new
active ingredient, tagetes oil.

BPPD has reviewed the data/information in support of the requirements for granting registration
under Section 3(c)(5) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). It has
been determined that the data/information submitted adequately satisfy current guideline
requirements (please refer to 40 CFR Subpart U § 158.2000).

On October 1, 2009, EPA announced a new policy to provide a more meaningful opportunity for
the public to participate on major registration decisions before they occur. According to this
policy, EPA provides a public comment period prior to making a registration decision for the
following types of applications: new active ingredients, first food use, first outdoor use, first
residential use; and any registration decisions for which the Agency believes there may be
substantial public interest.

Consistent with the policy of making registration actions more transparent, tagetes oil was
subject to a 30 day comment period as a "new active ingredient". The notice for this comment
period included the draft Biopesticides Registration Action Document (BRAD) and draft product
labels for the EPs, Bug Oil Food Use and Bug Oil Food Ornamental, which contain this new
active ingredient, tagetes oil. The docket identification (ID) number is EPA-HQ-OPP-2009-
0822. The Agency did not receive any comments on the registration of tagetes oil. Therefore, the
Agency is issuing the registration for this active ingredient. The Agency believes that based on
the risk assessment and information submitted in support of the registration of the EPs containing
tagetes oil, it is in the best interests of the public to issue the registration for Bug Oil Food Use
and Bug Oil Food Ornamental. The basis for this decision can be found in the risk assessment for
tagetes oil, which is characterized in this BRAD.

III. REGULATORY BACKGROUND

On September 18, 2009, EPA received an application filed by Exponent, 1150 Connecticut
Avenue, NW, Suite 1100, Washington, DC 20036, on behalf of Plant Impact pic, 12 South
Preston Office Village, Cuerden Way, Bamber Bridge, Preston, PR5 6BL, United Kingdom, to
register the products, Bug Oil Food Use (EPA File Symbol No. 85937-E) and Bug Oil
Ornamental (EPA File Symbol No. 85937-R) containing the new biochemical active ingredient,
tagetes oil, and the currently registered active ingredients, canola oil, thyme oil, and wintergreen
oil. A notice of receipt (NOR) of this application, allowing for a 30-day comment period, was
published in the Federal Register on December 16, 2009 (74 FR 66639). No comments were
received following this publication.

A. Classification

On July 6, 2006, the biochemical classification committee determined that tagetes oil is marigold
oil, which was previously classified as a biochemical in 1997 due to its nontoxic mode of action,
natural occurrence in the environment, and history of exposure to humans and the environment
demonstrating minimal toxicity. Tagetes oil is derived from Tagetes spp. (marigolds),
specifically, African marigold (Tagetes erectci) and Aztec marigold (Tagetes minuta). The mode
of action is repellency by tagetes oil alone and suffocation by tagetes oil in conjunction with the
other actives in the proposed EPs, canola oil, thyme oil, and wintergreen oil.

B. Food Clearances/Tolerances

The applicant filed a petition (PP 9F7619) proposing to establish an exemption from the
requirement of a tolerance for residues of tagetes oil in or on all food commodities. A notice of
filing (NOF), allowing for a 30-day comment period, was published in the Federal Register on
December 16, 2009 (74 FR 66644). No comments were received following this publication. The
Agency determined during the review of the petition that the active ingredient, tagetes oil, is an
edible oil and is exempt from the requirement of a tolerance as a minimal risk active ingredient
under 40 CFR 180.950(c). Therefore, the petition (PP 9F7619) filed by the applicant is no longer


-------

applicable, nor needed, for this new active ingredient, tagetes oil, and has been withdrawn by the
Agency.

IV. RISK ASSESSMENT

A.	Active Ingredient Characterization

Tagetes Oil is a new biochemical pesticide active ingredient intended for use as an
insecticide/acaricide for the control of mites, whiteflies, aphids, thrips, mealybugs, scales, and
pyslla on a variety of food crops. The active ingredient is extracted from the flowering herb,
Tagetes minuta (Muster John Henry or Mexican Marigold). There are many species within the
Tagetes genus. The herb is non-native to the United States, but is found in California, Hawaii,
and in most of the states on the east coast (USDA Plants Database, 2010). It has a widespread
geographic distribution, but is prevalent in subtropical and tropical climates. The major
constituents of the identified components of tagetes oil are terpenes, which are found in a variety
of essential oils.

Tagetes oil, as TagetespatulaL., T. erectaL., or T. minutaL. (T. glandulifera Schrank) is
approved by the U.S. Food and Drug Administration (FDA) for use in food as a natural flavoring
substance and natural adjuvant (in the oil form only) under 21 CFR 172.510. Reported uses of
tagetes oil as a food additive are in alcoholic beverages, nonalcoholic beverages, baked goods,
chewing gum, condiments (e.g., relishes), frozen dairy, gelatins (e.g., puddings), hard candy, and
soft candy (Burdock, 2005). Tagetes oil is also used in some cosmetics including shampoos,
soaps and lotions (EWG, 2010).

Descriptions of the product formulation and production process, formation of impurities, and
physical and chemical characteristics were examined by BPPD and found to be acceptable in
meeting current guideline standards.

All product chemistry data requirements for registration of tagetes oil have been satisfied.

For more information regarding product chemistry data requirements, refer to Tables 1 and 2 in
Appendix A.

B.	Human Health Assessment
1. Toxicology

For acute toxicity data requirements, toxicity categories are assigned based on the hazard(s)
identified from studies and/or information on file with the Agency. The active ingredient is
classified into Toxicity Category I, II, III or IV where Toxicity Category I indicates the highest
toxicity and Toxicity Category IV indicates the lowest toxicity.

Adequate mammalian toxicology data/information is available to support registration of tagetes
oil. All toxicology data requirements for tagetes oil have been satisfied.


-------
Tagetes Oil
Page 9 of 22

Biopesticides Registration Action Document

a.	Acute Toxicity

Acute toxicity testing is required to 1) determine systemic toxicity from acute exposure via the
dermal, inhalation and oral routes, 2) determine irritant effects from exposure to the eyes, and 3)
determine the potential for skin sensitization (allergic contact dermatitis).

Tier I acute toxicity studies submitted and reviewed showed that tagetes oil is a toxicity category
III (slightly toxic) compound via acute dermal route of exposure, based on testing at a limit dose
of 2000 mg a.i./kg in rats, and is moderately irritating to the skin based on the results of a
primary dermal irritation study in rabbits. Tagetes oil falls in Toxicity Category IV (not toxic) for
acute oral toxicity, acute inhalation toxicity, and primary eye irritation. Tagetes oil is minimally
irritating in the eye and is not a dermal sensitizer.

For more information regarding acute toxicity data requirements, refer to Table 3 in Appendix A.

b.	Subchronic Toxicity

Subchronic data are required to determine a no-observed-effect-level (NOEL) and any toxic
effects associated with repeated or continuous exposure to a test substance for a period of ninety
days.

Rationale was submitted for the subchronic [90-day oral (OCSPP 870.3100) and 90-day
inhalation (OCSPP 870.3465)] in lieu of data. BPPD determined that the rationale submitted was
acceptable based on the EPs toxicological and exposure profile, summarized below.

i.	Tagetes oil is an edible oil and is exempt from the requirement of a tolerance as a
minimal risk active ingredient under 40 CFR 180.950(c).

ii.	Tagetes oil is an edible oil and is already consumed in the human diet as it is used as a
food additive and FDA has approved the use of the oil (in oil form only) with no
limitations as a food additive under 21 CFR 172.510.

iii.	Significant exposure to humans is not anticipated based on low application rates and
rapid degradation in the environment.

iv.	Significant repeat exposure of tagetes oil to humans as a gas, vapor, or aerosol is not
anticipated based on the use pattern.

A waiver requested for the subchronic [90-day dermal (OCSPP 870.3250)] was granted by
BPPD, based on the EPs toxicological and exposure profile, summarized below.

i.	Prolonged dermal exposure is not expected because the product is not purposely applied
to the skin and handlers/applicators are required to wear appropriate PPE.

ii.	Tagetes oil is expected to volatilize rapidly after application.

For more information regarding the subchronic data requirements, refer to Table 3 in Appendix
A.

c.	Developmental Toxicity and Mutagenicity

A rationale for lack of toxicity was submitted for the developmental toxicity data requirement
(OCSPP 870.3700) in lieu of data. BPPD determined that the rationale submitted was acceptable
based on the EPs toxicological and exposure profile, summarized below.

i.	Tagetes oil is an edible oil and is exempt from the requirement of a tolerance as a
minimal risk active ingredient under 40 CFR 180.950(c).

ii.	Tagetes oil is an edible oil and is already consumed in the human diet as it is used as a
food additive and FDA has approved the use of the oil (in oil form only) with no
limitations as a food additive under 21 CFR 172.510.

iii.	Significant exposure to female humans is not anticipated based on low application rates,
appropriate PPE requirements on the label, and rapid degradation in the environment.

The tier I mutagenicity study [Ames test (OCSPP 870.5100)] submitted and reviewed showed
that tagetes oil concentrations of up to 5,000 ug/plate were not mutagenic with or without
metabolic activation. Rationale was submitted for the Tier I mutagenicity data requirement [in
vitro mammalian cell assay (OCSPP 870.5300 and 5375)] in lieu of data. BPPD determined that
the rationale submitted was acceptable based on the EPs toxicological and exposure profile,
summarized below.

i.	Tagetes oil is an edible oil and is exempt from the requirement of a tolerance as a
minimal risk active ingredient under 40 CFR 180.950(c).

ii.	Tagetes oil is an edible oil and is already consumed in the human diet as it is used as a
food additive and FDA has approved the use of the oil (in oil form only) with no
limitations as a food additive under 21 CFR 172.510.

iii.	Significant exposure to humans is not anticipated based on low application rates,
appropriate PPE requirements on the label, and rapid degradation in the environment.

For more information regarding developmental and mutagenicity data requirements, refer to
Table 3 in Appendix A.

d.	Tier II/Tier III

The data requirements were not required due to the nature of the active ingredient and its
intended uses in potential new EP products (insecticides and acaricides).

e.	Effects on the Endocrine System

As required under FFDCA section 408(p), EPA has developed the Endocrine Disruptor
Screening Program (EDSP) to determine whether certain substances (including pesticide active
and other ingredients) may have an effect in humans or wildlife similar to an effect produced by
a "naturally occurring estrogen, or other such endocrine effects as the Administrator may
designate." The EDSP employs a two-tiered approach to making the statutorily required


-------
Tagetes Oil
Page 11 of 22

Biopesticides Registration Action Document

determinations. Tier 1 consists of a battery of 11 screening assays to identify the potential of a
chemical substance to interact with the estrogen, androgen, or thyroid (E, A, or T) hormonal
systems. Chemicals that go through Tier 1 screening and are found to have the potential to
interact with E, A, or T hormonal systems will proceed to the next stage of the EDSP where EPA
will determine which, if any, of the Tier 2 tests are necessary based on the available data. Tier 2
testing is designed to identify any adverse endocrine related effects caused by the substance, and
establish a dose-response relationship between the dose and the E, A, or T effect.

Between October 2009 and February 2010, EPA issued test orders/data call-ins for the first
group of 67 chemicals, which contains 58 pesticide active ingredients and nine inert ingredients.
This list of chemicals was selected based on the potential for human exposure through pathways
such as food and water, residential activity, and certain post-application agricultural scenarios.
This list should not be construed as a list of known or likely endocrine disruptors.

Tagetes oil is not among the group of 58 pesticide active ingredients on the initial list to be
screened under the EDSP. Under FFDCA section 408(p) the Agency must screen all pesticide
chemicals. Accordingly, EPA anticipates issuing future EDSP test orders/data call-ins for all
pesticide active ingredients.

For further information on the status of the EDSP, the policies and procedures, the list of 67
chemicals, the test guidelines and the Tier 1 screening battery, please visit our website:
http://www.epa.gov/endo/.

2.	Dose Response Assessment

Because no toxicological endpoints were identified for this active ingredient, a dose response
assessment was not required.

3.	Drinking Water Exposure and Risk Characterization

No significant exposure via drinking water is expected when tagetes oil is used according to the
product label directions. The active ingredient biodegrades rapidly in the environment (59%
volatilization in 48 hours), is applied at low application rates and is not directly applied to water;
therefore, residues of tagetes oil are unlikely to accumulate in drinking water. In the unlikely
event that exposure via drinking water does occur, the health risk would be expected to be
minimal based on the low acute oral toxicity of tagetes oil and the fact that tagetes oil is an
edible oil and is exempt from the requirement of a tolerance as a minimal risk active ingredient
under 40 CFR 180.950(c).

4.	Occupational, Residential, School and Day Care Exposure and Risk Characterization

a. Occupational Exposure and Risk Characterization

An occupational exposure assessment was not conducted for tagetes oil, and is not required.
Appropriate PPE requirements on the label will mitigate any potential exposure to applicators
and/or handlers. Additionally, no relevant toxicological endpoints have been identified. Based on


-------
Tagetes Oil
Page 12 of 22

Biopesticides Registration Action Document

the data and information available to the Agency, anticipated exposure is not likely to result in
unreasonable risk to humans.

b. Residential, School and Day Care Exposure and Risk Characterization

Exposure to tagetes oil will be minimal in residential, school, and day care areas, as the product
containing this active ingredient is intended for use on horticultural and agricultural crops.

5.	Aggregate Exposure from Multiple Routes Including Dermal, Oral, and Inhalation

There is reasonable certainty that no harm to the U.S. population will result from aggregate
exposure to tagetes oil. This includes all exposures for which there is reliable information. The
Agency arrived at this conclusion based on the lack of toxicity of this active ingredient and the
already widespread exposure without any reported adverse effects on human health. The risks
from aggregate exposure via oral, dermal and inhalation exposure are a compilation of three low-
risk exposure scenarios and are negligible.

6.	Cumulative Effects

Pursuant to FFDCA section 408(b)(2)(D)(v), EPA has considered available information
concerning the cumulative effects of tagetes oil residues and other substances that have a
common mechanism of toxicity. No toxicological endpoints have been established for exposure
to tagetes oil; therefore, cumulative effects with other substances that share a common
mechanism of toxicity are not expected.

7.	Risk Characterization

The Agency considered human exposure to tagetes oil in light of the relevant safety factors in
FQPA and FIFRA. A determination has been made that no unreasonable adverse effects to the
U.S. population in general, and to infants and children in particular, will result from the use of
tagetes oil when label instructions are followed.

C. ENVIRONMENTAL ASSESSMENT

1. Ecological Hazards

Adequate nontarget toxicology data/information is available to support registration of tagetes oil
with the submission of nontarget toxicology data on the EPs. All nontarget toxicology data
requirements for tagetes oil have been satisfied.

The EPs are practically nontoxic to birds, fish and aquatic invertebrates and is not phytotoxic.
The EPs are practically nontoxic via exposure through contact to nontarget insects.

For more information regarding nontarget organism toxicity data requirements, refer to Table 4
in Appendix A.


-------
Tagetes Oil
Page 13 of 22

Biopesticides Registration Action Document

2.	Environmental Fate and Ground Water Data

Environmental fate and groundwater data are not required at this time because the results of the
nontarget organism toxicity assessment (Tier I data requirements) did not trigger these Tier II
data requirements.

3.	Ecological Exposure and Risk Characterization

Toxicity studies have not been submitted for tagetes oil. A lack of toxicity rationale and data on
the proposed EPs have been submitted to fulfill these data requirements. According to the
applicant, the active ingredients act synergistically; thus, the combination of these chemicals is
more potent as an insecticide than each ingredient alone. Therefore, the toxicological profile of
the EPs are germane to the risk assessment rather than the toxicological profile of tagetes oil
alone. For registration of the proposed EPs, the Agency has bridged the nontarget organism
toxicology data from the EPs to the active ingredient, tagetes oil. The product is a contact
insecticide that operates through a physical mode of action. The product is practically nontoxic
to birds, fish and aquatic invertebrates and is not phytotoxic; toxic endpoints have not been
identified for these species. The product is practically nontoxic via exposure through contact to
nontarget insects. Based on the data submitted, the Agency has indicated in its review that the
product may be moderately toxic via oral exposure to nontarget insects; however, no mortality
was observed at the highest dose tested in the study. Additionally, significant oral exposure is
not anticipated as the product is a contact insecticide and is expected to degrade rapidly in the
environment. Toxic endpoints have not been identified for nontarget insects via the oral or
contact route of exposure. The results of the submitted studies and screening-level risk
assessment indicate that use of the product according to label instructions should not result in
adverse effects to birds, fish, aquatic invertebrates, plants or nontarget insects.

4.	Endangered Species Assessment

The Agency has not conducted a risk assessment that supports a complete endangered species
determination. The ecological risk assessment planned during registration review will allow the
Agency to determine whether tagetes oil's use has "no effect" or "may effect" federally listed
threatened or endangered species (listed species) or their designated critical habitats. When an
assessment concludes that a pesticide's use "may affect" a listed species or its designated critical
habitat, the Agency will consult with the U.S. Fish and Wildlife Service and/or National Marine
Fisheries Services (the Services) as appropriate.

D. EFFICACY DATA

Product performance data must be developed for all pesticides to ensure that pesticide products
will perform as intended and that unnecessary pesticide exposure to the environment will not
occur as a result of the use of ineffective products. The Agency reserves the right to require on a
case-by- case basis, submission of efficacy data for any pesticide product registered or proposed
for registration that are intended to be used to control a pest of significance public health
importance and a public health pest as defined in FIFRA section 28(d) and section 2(nn). For
further guidance on product performance requirement, refer to Pesticide Registration Notice (PR)

Biopesticides Registration Action Document

Notices 96-7, 2002-1 and Explanation of Statutory Framework for Risk-Benefit Balancing for
Public Health Pesticides (http://www.epa.gov/PR Notices/prl996-7.pdf)

(http://www.ea.gov/PR Notices/pr2002-1 .pdf) and (http://www.epa.gov/pesticides/health/risk-
benefit.htm).

The EPs submitted with this new active ingredient did not list pests of significance public health
importance or a public health pest as defined in FIFRA section 28(d) and section 2(nn).
Therefore, product performance (efficacy) was not evaluated.

V. Risk Management Decision

A.	Determination of Eligibility for Registration

Section 3(c)(5) of FIFRA provides for the registration of a new active ingredient if it is
determined that: (A) its composition warrants proposed claims; (B) its labeling and other
materials comply with the requirements of FIFRA; (C) it will perform its intended function
without unreasonable adverse effects on the environment; and (D) when used in accordance with
widespread and commonly recognized practice, it will not generally cause unreasonable adverse
effects on the environment.

The four criteria of the Eligibility Determination for Pesticidal Active Ingredients are satisfied by
the science assessments supporting products containing the technical grade active ingredient,
tagetes oil. Such products are not expected to cause unreasonable adverse effects. Therefore,
tagetes oil as a technical grade active ingredient is eligible for registration for the labeled uses.

B.	Regulatory Decision

The data submitted fulfill the registration requirements of tagetes oil for use as an insecticide and
acaricide. Refer to Appendix B for product-specific information.

Conditional/Unconditional Registration

All data requirements are fulfilled, and EPA determined that an unconditional registration of
tagetes oil is appropriate.

C.	Environmental Justice

EPA seeks to achieve environmental justice—the fair treatment and meaningful involvement of
all people regardless of race, color, national origin, or income—with respect to the development,
implementation, and enforcement of environmental laws, regulations, and policies. At this time,
EPA does not believe that use of tagetes oil pesticide products will cause harm or a
disproportionate impact on at-risk communities. For additional information regarding
environmental justice issues, please visit EPA's website at
http: ic ii'ic. epa. gov/comyliance/environmentaliustice/index. html.

VI.	ACTIONS REQUIRED BY REGISTRANTS

EPA evaluated all data submitted in connection with the registration of the tagetes oil pesticide
products and determined that these data are sufficient to satisfy current registration data
requirements. At this time, no additional data must be submitted to EPA for these particular
products. For new uses and/or changes to existing uses, EPA may require additional data.

Notwithstanding the information stated in the previous paragraph, it should be clearly understood
that certain specific data are required to be reported to EPA as a requirement for maintaining the
Federal registration for a pesticide product. A brief summary of these types of data are listed
below.

A.	Reporting of Adverse Effects

Pursuant to FIFRA section 6(a)(2), reports of all incidents of adverse effects to the environment
must be submitted to EPA.

B.	Reporting ofHypersensitivity Incidents

Additionally, all incidents of hypersensitivity (including both suspected and confirmed incidents)
must be reported to the Agency under the provisions of 40 CFR Part 158.2050(d).

VII.	Appendix A. Data Requirements (40 CFR Part 158-Subpart U)

Not a sensitizer. No positive signs of
reactivity at 24 and 48 hours after challenge in
test and naive control animals after three
consecutive weekly inductions.



47868217

90-Day oral toxicity
(870.3100)

Rationale was provided in lieu of a 90-day
oral study. Tagetes oil is exempt from the
requirement of a tolerance as a minimal risk
active ingredient under 40 CFR 158.950(c).
Significant exposure is not expected based on
low application rates and rapid degradation in
the environment. Tagetes oil is an edible oil
and is already consumed in the human diet as
it is used as a food additive in alcoholic
beverages, baked goods, condiments, frozen
dairy, gelatins, puddings, candy, and
nonalcoholic beverages.



48339002

90-Day dermal toxicity
(870.3250)

Waived: prolonged dermal exposure not
anticipated based on use pattern, volatility
(anticipated volatility-vapor pressure data
must be submitted) of active ingredient and
appropriate PPE requirements on label.





90-Day inhalation toxicity
(870.3465)

Rationale was provided in lieu of a 90-day
inhalation study. Significant repeat exposure
to humans to tagetes oil as a gas, vapor or
aerosol is not anticipated based in the use
pattern. Additionally, significant exposure is
not expected based on low application rates
and rapid degradation in the environment.

Not mutagenic with or without metabolic
activation in Salmonella typhimurium strains
TA 98, TA 1537, TA 100, TA 1535 and
Escherichia coli strain Wp2uvrA.

Rationale was provided in lieu of an in vitro
mammalian cell assay. Significant exposure
to humans is not anticipated based on low
application rates, appropriate PPE
requirements on the label, and rapid
degradation in the environment. Additionally,
humans are already exposed to tagetes oil in
the diet, as it is an edible oil and is used as a
food additive in alcoholic beverages, baked
goods, condiments, frozen dairy, gelatins,
puddings, candy, and nonalcoholic beverages.



48329205

Developmental toxicity
(870.3700)

Rationale was provided in lieu of a
developmental study. Significant exposure to
female humans is not anticipated based on
low application rates, appropriate PPE
requirements on the label, and rapid
degradation in the environment. Humans are
also already exposed to tagetes oil, as it is an
edible oil and is used as a food additive in
alcoholic beverages, baked goods,
condiments, frozen dairy, gelatins, puddings,
candy, and nonalcoholic beverages.
