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 EDEN Bioscience Corporation, 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.
EDEN Bioscience Corporation
EPA has received a pesticide petition (3F6765) from EDEN Bioscience Corporation, 3830 Monte Villa Parkway, Bothell, WA 98021-6942, 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 amendment of the existing tolerance exemption for the biochemical pesticide harpin protein on all raw agricultural commodities. Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended, EDEN Bioscience Corporation has submitted the following summary of information, data, and arguments in support of their pesticide petition. This summary was prepared by the EDEN Bioscience Corporation; 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.
In the Federal Register of September 9, 1999 (64 FR 49010) (FRL-6095-9), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C. 346a(d), announcing the filing of a pesticide tolerance petition (PP 9F6027) by the EDEN Bioscience Corporation. This notice included a summary of the petition prepared by the petitioner and this summary contained conclusions and arguments to support its conclusion that the petition complied with the Food Quality Protection Act (FQPA) of 1996. This petition requested that 40 CFR part 180 be amended by establishing an exemption from the requirement of a tolerance for the biochemical pesticide harpin protein in or on all food crops. The final rule exempted the biochemical harpin from the requirement of a tolerance on food commodities when applied/used in agricultural fields and greenhouses for the management of plant diseases, the significant improvement in growth and yields, and the suppression of certain insects and other pests. EPA published a final rule establishing a tolerance exemption in the Federal Register of May 3, 2000 (65 FR 25660) (FRL-6497-4), amending 40 CFR 180.1204. Research on other harpin proteins that are similar to this active ingredient indicates that many of these proteins also exhibit activities of commercial value in crop production. Because 40 CFR 180.1204 does not specify the scope of harpin proteins that are exempt, EDEN proposes to clarify this exemption by specifying the criteria a protein must meet in order to be subject to the exemption.
A. Product Name and Proposed Use Practices
All products containing harpin protein(s) that meet the specifications proposed in this exemption. Products containing harpin protein are used to enhance plant growth, quality, and yield, to improve overall plant health, and to aid in pest management.
B. Product Identity/Chemistry
1. Identity of the pesticide and corresponding residues. Harpin proteins share several identifying characteristics. Harpin proteins are less than 100 kilo Dalton (kD) in size. They are acidic proteins, with Daltons an iso-electric point (pI) of less than 7.0. They are comprised of at least 10% of the amino acid glycine and contain no more than one cystine amino acid residue. Harpin proteins elicit the hypersensitive response (HR). HR is characterized as rapid, localized cell death in plant tissue after infiltration of harpin into the intercellular spaces of plant leaves. Harpin proteins possess a common secondary structure consisting of alpha and beta units that form an HR domain. They are readily degraded by proteinase, and are heat stable, meaning that they retain HR activity when heated to 65o C for 20 minutes.
2. Magnitude of residue at the time of harvest and method used to determine the residue. No residues of harpin protein are expected to occur at the time of harvest because harpin protein is rapidly degraded by environmental factors such microbial digestion and ultraviolet (UV) irradiation. For example, studies demonstrate that harpin is degraded within minutes by SubtilisinA, a microbial enzyme that Start Printed Page 4154occurs commonly in the environment. In fact, this mode of rapid degradation in the environment is one of the proposed criteria for including a harpin protein in the exemption from the requirement of a tolerance. Specifically, the proposed criterion is “no protein fragments >3.5 kD after 15 minutes degradation with SubtilisinA.” Residue studies submitted to support the existing exemption from tolerance demonstrate that harpin protein is not detectable at the time of harvest. In these studies, no harpin protein residues could be detected in samples taken immediately after harpin protein was applied at the maximum application rate. Because there is no detectable residue at harvest, an analytical method is not relevant.
3. A statement of why an analytical method for detecting and measuring the levels of the pesticide residue are not needed. No analytical method to detect and measure residues of harpin protein is needed because harpin protein poses no hazard to humans. Results of mammalian toxicology studies conducted at the limit dose indicate no observed adverse effects associated with harpin protein. Moreover, no residues of harpin protein are expected to occur at the time of harvest because harpin protein is rapidly degraded by environmental factors such as microbial digestion and UV irradiation.
C. Mammalian Toxicological Profile
Products containing harpin proteins exhibit little or no mammalian toxicity. To qualify for exemption, a harpin protein must exhibit a rat acute oral toxicity lethal dose (LD50) of greater than 5,000 mg product/kg body weight Toxicity Category IV. The source(s) of genetic material that encode the harpin protein(s) is limited to bacterial plant pathogens that are not known to be pathogenic to mammals. Harpin proteins must be readily degraded by a proteinase that is representative of environmental conditions. Specifically, there must be no protein fragments of a size greater than 3.5 kD after 15 minutes degradation with SubtilisinA, a proteinase that is common and widespread in the environment. Further, harpin proteins have a nontoxic mode of action; they activate the treated plant's own growth and defense systems. EDEN Bioscience Corporation has concluded that harpin proteins pose no unique or additional risk to children or infants, and proposes an exemption from the requirement of a tolerance for all harpin proteins that meet the following specifications:
1. Consists of a protein <100 kD in size that is acidic pI <7.0, glycine rich >10% and contains no more than one cystine residue.
2. The source(s) of genetic material encoding the protein are bacterial plant pathogens that are not known to be mammalian pathogens.
3. Elicits the hypersensitive response (HR) which is characterized as rapid, localized cell death in plant tissue after infiltration of harpin into the intercellular spaces of plant leaves.
4. Possesses a common secondary structure consisting of alpha and beta units that form an HR domain.
5. Is heat stable (retains HR activity when heated to 65o C for 20 minutes).
6. Is readily degraded by a proteinase representative of environmental conditions (no protein fragments >3.5 kDa after 15 minutes degradation with SubtilisinA).
7. Exhibits a rat acute oral toxicity LD50 of >5,000 mg product/kg body weight.
D. Aggregate Exposure
1. Dietary exposure—i. Food. Because harpin proteins are rapidly degraded in the environment by common proteinases, UV irradiation, and oxidizing agents, no active ingredient residues are detectable, using available methods, on treated crops even immediately after application. Dietary exposure to harpin via consumption of treated food or feed is negligible, if any at all.
ii. Drinking water. Harpin proteins readily degraded by common proteinases and UV irradiation, and are highly sensitive to very small amounts of chlorine or similar oxidizing agents as contained in many municipal water systems. Therefore, residues of harpin are unlikely to occur in drinking water or food, given its rapid degradation in soil and water.
2. Non-dietary exposure. The company believes that the potential for non-dietary exposure to the general population including infants and children is unlikely as the proposed use sites are primarily commercial, agricultural and horticultural settings and that non-dietary exposures would not be expected to pose any quantifiable risks due to lack of residues of toxicological concern. Increased nondietary exposure of harpin via home and garden use, etc., is not considered likely because of the typically low use rates and volumes, and the lack of persistence of the active ingredient in the environment.
E. Cumulative Exposure
Consideration of a common mode of toxicity is not appropriate, given that there is no indication of mammalian toxicity of harpin protein and no information that indicates that toxic effects would be cumulative with any other compounds. Moreover, harpin proteins do not exhibit a toxic mode of action in its target pests or diseases.
F. Safety Determination
1. U.S. population. Harpin's lack of toxicity is demonstrated by the results of acute toxicity testing in mammals in which harpin causes no adverse effects when dosed orally at the limit dose for the study. Thus, the aggregate exposure to harpin over a lifetime should pose negligible risks to human health.
2. Infants and children. Based on the lack of toxicity and low exposure, there is a reasonable certainty that no harm to infants, children, or adults will result from aggregate exposure to harpin residues. Exempting harpin proteins that meet the specified criteria from the requirement of a tolerance should pose no significant risk to humans or the environment.
G. Effects on the Immune and Endocrine Systems
EDEN Bioscience Corporation has no information to suggest that harpin proteins will adversely affect the immune or endocrine systems.
H. Existing Tolerances
An existing exemption from tolerance has been established for harpin protein in the United States, 40 CFR 180.1204.
I. International Tolerances
EDEN Bioscience Corporation is not aware of any tolerances, exemptions from tolerance or maximum residue levels issued for harpin protein outside of the United States.End Supplemental Information
