Summary of Petition

The petitioner's summary of the pesticide petition is printed below as required by FFDCA section 408(d)(3). The summary of the petition was prepared by the petitioner and represents the view of the petitioner. The petition summary announces the availability of a description of the analytical methods available to EPA for the detection and measurement of the pesticide chemical residues or an explanation of why no such method is needed.

Interregional Research Project Number 4 (IR-4)

PP 3E6751

EPA has received a pesticide petition (3E6751) from Interregional Research Project Number 4 (IR-4), New Jersey Agricultural Experiment Station, Technology Center of New Jersey, Technology Centre of New Jersey, 681 U.S. Highway #1 South, North Brunswick, NJ 08902-3390, on behalf of KHH BioSci Inc., 920 Campus Drive, Suite 101, Raleigh, NC 27606 proposing pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d) to establish a tolerance exemption for the biochemical pesticide Reynoutria sachalinensis in all food commodities.

Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended, the aforesaid IR-4, on behalf of KHH BioSci Inc., has submitted the following summary of information, data, and arguments in support of the pesticide petition. This summary was prepared by IR-4 on behalf of KHH BioSci Inc., 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

Reynoutria sachalinensis, is an extract of a naturally occurring plant of that botanical name, and is proposed for use to reduce the incidence of plant diseases. When applied just prior to disease incidence, Reynoutria sachalinensis induces plant defenses making treated plants more resistant to certain diseases. Reynoutria sachalinensis is applied to ornamental and food crops in a 0.5 to 1% solution at a rate of up to 100 gallons of solution per acre. The pesticide is registered for use in non-food crops (EPA Registration # 72179-2). This petition proposes to establish a permanent exemption from the requirement of a tolerance for residues of Reynoutria sachalinensis in or on all food commodities.

B. Product Identity/Chemistry

1. Identity of the pesticide and corresponding residues. The pesticide and corresponding residues are identified as Reynoutria sachalinensis, a plant extract. Residues resulting from the use of Reynoutria sachalinensis extract on food crops could be difficult to characterize since many of the same phenolic compounds promoted by Reynoutria sachalinensis extract, are already present in vegetables. A waiver has been requested for nature of the residue studies on Reynoutria sachalinensis extract.

2. Magnitude of residue at the time of harvest and method used to determine the residue. Reynoutria sachalinensis is a plant extract. An analytical method for detecting residues was not submitted as this petition proposes an exemption from the requirement of a tolerance.

3. A statement of why an analytical method for detecting and measuring the levels of the pesticide residue are not needed. An analytical method for enforcement purposes to detect residues was not submitted as this petition proposes an exemption from the requirement of a tolerance.

C. Mammalian Toxicological Profile

Acute toxicity studies on the technical active ingredient (manufacturing use product) and formulated material have been submitted and reviewed in support of the existing product registration for greenhouse, non-food use. These studies and EPA's conclusions are summarized below.

An acute oral toxicity test was performed using the manufacturing use product, Milsana Bioprotectant (technical active ingredient). Based on a lack of mortality observed in albino rats, the oral lethal dose (LD)₅₀ of the technical active ingredient product, was >5,000 milligrams/kilogram (mg/kg); toxicity category IV.

An acute oral toxicity study of Milsana Bioprotectant Concentrate (Milsana^®, a formulated end-use product) was conducted. Based on a lack of mortality observed in albino rats, the oral LD₅₀ of the end-use product was >5,000 mg/kg; toxicity category IV.

An acute dermal toxicity study was conducted using the manufacturing use product, Milsana Bioprotectant (technical active ingredient). Based on a lack of mortality observed in albino rabbits, the LD₅₀ was >2,000 mg/kg; toxicity category III.

An acute dermal toxicity study of Milsana Bioprotectant Concentrate (Milsana^®, formulated end-use product) was conducted. Based on a lack of mortality observed in albino rabbits, the LD₅₀ was >2,000 mg/kg; toxicity category III.

An acute inhalation toxicity study of Milsana^®, a formulated end-use product was conducted in albino rats. The conclusion was that the lethal concentration (LC)₅₀ is >2.6 milligram/Liter (mg/L); toxicity category IV.

An acute eye irritation study of Milsana Bioprotectant Concentrate Milsana^®, a formulated end-use product) was conducted. The study demonstrated that a dose of 0.1 milliliter (mL) resulted in the highest average ocular irritation index was 23.3, recorded 1-hour after instillation of the test substance into the eyes of albino rabbits. This classifies Milsana^® as moderately irritating with a toxicity category II. However, when the technical grade of the active ingredient (TGAI) was used as a test material, the highest average ocular irritation recorded was 12.2, toxicity category III. Therefore, it is reasonable to conclude that the formulated end use product contains an eye irritant.

An acute dermal irritation study of Milsana Bioprotectant Concentrate (Milsana^®, formulated end-use product) was conducted in albino rabbits. The conclusion was that dermal application of 0.5 gram (g) of liquid product did not cause any dermal irritation symptoms up to 72 hours post dosing; toxicity category IV.

A skin sensitization study of Milsana Bioprotectant Concentrate (Milsana^®, formulated end-use product) was conducted with albino guinea pigs. The conclusion was that the test substance is not considered to be a contact sensitizer in guinea pigs by the Buehler method.

Based on these studies, we concluded that Reynoutria sachalinensis does not present an acute toxicity risk to mammals. Since no adverse effects were observed in the Tier I acute toxicity studies, data waivers were requested for the following toxicology studies: Genotoxicity study, immune response, mutagenicity, chronic toxicity, and developmental toxicity. In addition, the following rationales were used as a basis for the data waiver requests:

1. Researchers, manufacturers, and other workers have worked with Reynoutria sachalinensis and it is currently used in greenhouse production without report of any adverse health effects.

2. Reynoutria sachalinensis is widely distributed in the environment.

3. The label will require applicators and other handlers to wear personal protective equipment (PPE), to mitigate against exposure.

D. Aggregate Exposure

1. Dietary exposure—i. Food. Dietary exposure to Reynoutria sachalinensis, should not be of concern due to the low toxicity shown in the acute toxicity studies previously submitted. In addition, Reynoutria sachalinensis is widespread throughout the United States, Europe, and Asia and is already found in foods, animals feeds, and medicines (MRID 44821916). Reynoutria sachalinensis activates phenolics in plants which can be found in a wide variety of commonly consumed vegetables and herbs. No adverse health issues for man, animals, or plants have been associated with the plant. Exposure to the active ingredient from its pesticidal use is anticipated to be very low due to the low application rate which results in negligible residues compared to consumption of Reynoutria sachalinensis as a food.

ii. Drinking water. Reynoutria sachalinensis is a naturally occurring plant that is already widespread in the environment. It commonly grows along rivers and is not considered to be a risk to drinking water. Percolation through soil and municipal treatment of drinking water would reduce the possibility of exposure of Reynoutria sachalinensis through the drinking water. The formulated end use product is an extract of this plant, and any residues that may result from its pesticidal use would be expected to behave similarly to leachates of leaf litter and plant exudates in the environment.

2. Non-dietary exposure. The potential for non-occupational, non-dietary exposure to the general population is not expected to be significant and is not expected to present any risk of adverse health effects.

E. Cumulative Exposure

There are no other products-registered for food use containing Reynoutria sachalinensis as the active ingredient, so dietary exposure from other pesticidal uses is not likely. The plant has been consumed in the human diet in Japan for generations without any known adverse effects. Researchers, manufacturers, and other workers have applied Reynoutria sachalinensis under greenhouse production without report of any adverse health effects to greenhouse workers. In addition, the label will require pesticide applicators and other handlers to wear personal protective equipment (PPE), to mitigate exposure.

F. Safety Determination

1. U.S. population. Reynoutria sachalinensis is a naturally occurring plant. This plant has low toxicity as demonstrated by the acute oral toxicity study in rats. Based on this information, IR-4 is of the opinion that the aggregate exposure to Reynoutria sachalinensis over a lifetime should not change with application of Reynoutria sachalinensis. Thus, there is a reasonable certainty that no harm will result from aggregate exposure to Reynoutria sachalinensis. The data requirements for granting the greenhouse nonfood use registration under section 3(c)(5) of FIFRA has been reviewed by BPPD. The mammalian toxicology and ecological effects data requirements for Reynoutria sachalinensis extract have been fulfilled for the nonfood greenhouse use. Additional waivers have been developed for the food use. Product analysis data requirements have adequately satisfied EPA registrations for the greenhouse, nonfood use of the end use product, (EPA Registration # 72719-2) and the manufacturing use product (EPA Registration # 72719-1) which were approved on September 29, 2000. The composition of the products in the existing registration and this registration are identical.

2. Infants and children. Based on the lack of toxicity and low exposure, there is reasonable certainty that no harm to infants, children, or adults will result from aggregate exposure to Reynoutria sachalinensis. In addition, Reynoutria sachalinensis is widespread throughout the United States, Europe, and Asia and is already found in foods, animals feeds, and in medicines (MRID 44821916). The plant has been consumed in the human diet in Japan for generations without any known adverse effects. The active components stimulated by Reynoutria sachalinensis are phenolics which have health benefits and are already present in vegetables. Exempting Reynoutria sachalinensis from the requirement of a tolerance should pose no significant risk to humans or the environment.

G. Effects on the Immune and Endocrine Systems

To date there is no evidence to suggest that Reynoutria sachalinensis functions in a manner similar to any known hormone, or that it acts as an endocrine disrupter.

H. Efficacy

When applied to certain crop plants, this product raises the plants natural defense system by increasing the existing phenolic compounds in the leaf tissue. Current research indicates that the plant diseases affected by these natural phytoalexins are powdery mildews, gray mold, and fire blight. These diseases are economically important problems in both ornamental and food crop plants.

I. Existing Tolerances

There are no existing tolerances of any type for the extract of Reynoutria sachalinensis in the United States.

J. International Tolerances

The IR-4 program and the registrant, KHH BioSci, Inc., are not aware of any tolerances, exemptions from tolerance or maximum residue levels (MRLs) issued for the extract of Reynoutria sachalinensis outside of the United States. No MRLs have been established for the extract of Reynoutria sachalinensis by the Codex Alimentarius Commission.
