Agrotol International
9F6065
EPA has received a pesticide petition (9F06065) from Agrotol
International, 7322 Southwest Freeway, Suite 1400, Houston, TX 77074,
proposing, pursuant to section 408(d) of the Federal Food, Drug, and
Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180 to
establish an exemption from the requirement of a tolerance for the
biochemical pesticide phosphorous acid.
Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended,
Agrotol International has submitted the following summary of
information, data, and arguments in support of their pesticide
petition. This summary was prepared by Agrotol International and EPA
has not fully evaluated the merits of the pesticide petition. The
summary may have been edited by EPA if the terminology used was
unclear, the summary contained extraneous material, or the summary
unintentionally made the reader conclude that the findings reflected
EPA's position and not the position of the petitioner.
A. Product Name and Proposed Use Practices
Agtrol International has applied for registrations of two products
containing phosphorous acid as the sole active ingredient (a.i). One
product, Phosphorous Acid Technical, is a manufacturing-use product
containing the a.i at 71%. This product is intended for use in
formulating fungicidal products for application to terrestrial food
crops. The other product, Agri-Phos Agricultural Fungicide, is an end-
use product containing the 56.2% mono- and dibasic sodium, potassium
and ammonium salts of phosphorous acid (36.3% phosphorous acid). This
product is a fungicide intended for application to terrestrial food
crops, i.e., avocado, Brassica crops, caneberry, citrus, curcubit
crops, ginseng, grape, hops, leafy vegetables, onions (dry bulb),
pineapple, pome fruit, strawberry, and tomato.
B. Product Identity/Chemistry
1. Identity of the pesticide and corresponding residues--plant
metabolism. Phosphorous acid is rapidly degraded in the environment to
yield hydrogen and phosphite ions. Release of hydrogen ions will
increase the pH of the plants surface, which will be moderated by the
amount of neutralizing ions present, the buffering capacity, and the
amount of dilution possible. Phosphite ions are available for uptake by
plants usually in the form of ammonium, calcium, and potassium and
sodium phosphites (phosphite salts).
2. Magnitude of residue at the time of harvest and method used to
determine the residue. Magnitude of residue Agtrol has requested a
waiver for all residue chemistry data requirements because phosphorous
acid per se is not expected to be found in or on raw agricultural
commodities (RAC). Phosphorous acid sprayed on plants is expected to
dissociate rapidly releasing hydrogen and phosphite ions. The ions are
available for uptake by plants usually in the form of ammonium, calcium
and potassium and sodium phosphites (phosphite salts). Many phosphite
salts are generally recognized as safe (GRAS). See 21 CFR 182.3616,
182.3637, 182.3739, 182.3766, 182.3796, and 184.1764. Moreover, natural
means are expected to moderate the accumulation of these ions on
plants.
3. Analytical method. Agtrol International has not submitted a
practical analytical method for the detection and measurement of
pesticide chemical residues. Phosphorous acid per se is not expected to
be found in or on RACs, because once this chemical is released into the
environment it dissociates rapidly to form hydrogen and phosphite ions.
C. Mammalian Toxicological Profile
1. Acute toxicity. Phosphorous acid is of high acute toxicity
through the oral, dermal, and inhalation routes of exposure.
Phosphorous acid is corrosive to eyes and skin. However, results of
studies conducted on Agri-Phos Agricultural Fungicide, the end-use
product for which Agtrol International has applied for registration,
demonstrate that this product has a low order of toxicity. The acute
oral LD50 in the rat was greater than 5,000 milligrams per
kilograms (mg/kg) of bodyweight. The acute dermal LD50 in
the rat was greater than 5,000 mg/kg of bodyweight. The acute
inhalation LC50 in the rat was greater than 2.06 milligrams
per liter (mg/L). The product was found slightly irritating to the skin
of guinea pigs and produced irritation to the eyes or rabbits that
cleared within 48 hours. The product was not positive in guinea pigs
for skin sensitization.
2. Developmental/reproductive effects, chronic effects and
carcinogenicity. There is adequate information available from
literature sources to characterize the toxicity of phosphorous acid.
Phosphorous acid can affect human health through inhalation of mist,
ingestion, and contact with the skin and eyes. It will cause corrosive
effects (burns or irreversible damage) to the eyes, skin, throat,
digestive tract, upper respiratory tract and nose. Signs of
overexposure to this chemical are severe burning of eyes and skin,
possible nausea and vomiting, coughing, burning and tightness of the
chest and shortness of breath. Based on corrosiveness and then current
use patterns for the mineral acids, EPA did not require these studies
as part of the Reregistration Eligibility Decision on Mineral Acids
(EPA 738-R-029; December 1993).
3. Endocrine disruption. Phosphorous acid does not belong to a
class of chemicals known or suspected of having adverse effects on the
endocrine system. Further, Agtrol International is not aware of any
evidence that phosphorous acid has any effect on endocrine function.
Last, there is no evidence that phosphorous acid bioaccumulates in the
environment.
D. Aggregate Exposure
1. Dietary exposure--i. Food. No dietary exposure is expected. When
phosphorous acid is applied to growing crops in the environment it
rapidly dissociates to form hydrogen and phosphite ions.
ii. Drinking water--drinking water exposure. No significant
exposure is expected to result from phosphorous acid because it is
likely to be biodegraded in the terrestrial and aquatic environments to
hydrogen and phosphite ions. The effects on humans resulting from
anticipated concentrations to these ions due to
[[Page 70258]]
agricultural uses will be moderated by natural means. Moreover, there
is no potential for either ion to be significantly accumulated by the
biota. Phosphorous acid is not regulated under the Safe Drinking Water
Act; therefore; no maximum contaminant level (MCL) has been established
for it.
2. Non-dietary exposure. The primary non-pesticidal uses of
phosphorous acid are industrial in closed production systems. There are
no residential, indoor, school, or day care uses proposed for this
product. The proposed use pattern is for agricultural food crops.
Therefore, there is no potential for non-occupational exposure to the
general population.
E. Cumulative Exposure
Agri-Phos Agricultural Fungicide may share a common metabolic
mechanism with other salts of phosphorous acid (such as calcium);
however, due to their limited use, these other salts are not expected
to pose significant contributions to the cumulative effects from the
agricultural fungicidal use of Agri-Phos Agricultural Fungicide.
F. Safety Determination
1. U.S. population. Aggregate exposure to phosphorous acid is
expected to be minimal. There is very little potential for exposure to
phosphorous acid in drinking water and from non-dietary, non-
occupational exposures. This chemical will be applied to agricultural
food crops by commercial applicators. Once released into the
environment, the chemical rapidly dissociates to form hydrogen and
phosphite ions. The hydrogen ions affect pH, but this is moderated by
natural means. Many phosphite salts are GRAS. See 21 CFR 182.3616,
182.3637, 182.3739, 182.3766, 182.3796, and 184.1764. Therefore, the
health risk to humans is negligible based on the low toxicity of these
ions and a low application rate for the a.i, and one can conclude that
there is a reasonable certainty that no harm will result from aggregate
exposure to phosphorous acid.
2. Infants and children. Aggregate exposure to phosphorous acid is
expected to be minimal. There is very little potential for exposure to
phosphorous acid in drinking water and from non-dietary, non-
occupational exposures. This chemical will be applied to agricultural
food crops by commercial applicators. Once released into the
environment, the chemical rapidly dissociates to form hydrogen and
phosphite ions. The hydrogen ions affect pH, but this is moderated by
natural means. Many phosphite salts are GRAS. See 21 CFR 182.3616,
182.3637, 182.3739, 182.3766, 182.3796, and 184.1764. Therefore, the
health risk to humans is negligible based on the low toxicity of these
ions and a low application rate for the a.i, and one can conclude that
there is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to phosphorous acid residues.
G. Effects on the Immune and Endocrine Systems
Phosphorous acid does not belong to a class of chemicals known or
suspected of having adverse effects on the immune and endocrine
systems. Further, Agtrol International is not aware of any evidence
that phosphorous acid has any effect on immune and endocrine functions.
Last, there is no evidence that phosphorous acid bioaccumulates in the
environment.
H. Existing Tolerances
No tolerances have been established for residues of phosphorous
acid in RACs and or processed food/feed. Disodium phosphate,
monoammonium phosphate, diammonium phosphate and potassium phosphate
have been exempted from the requirement of a tolerance under 40 CFR
part 180.1001.
I. International Tolerances
No maximum residue levels (MRLs) have been established for
phosphorous acid by the Codex Alimentarius Commission (CODEX).
