Summary of Petition
The petitioner's summary of the pesticide petition (PP) 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.
Mycogen Seeds c/o Dow AgroSciences LLC
PP 3F6785
EPA has received a pesticide petition (3F6785) from Mycogen Seeds c/o Dow AgroSciences LLC, 9330 Zionsville Road, Indianapolis, IN 46268, proposing pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 174 to establish an exemption from the requirement of a tolerance for the plant-incorporated protectant Bacillus thuringiensis Cry34Ab1 and Cry35Ab1 proteins and the genetic material necessary for their production in corn. Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended, Mycogen Seeds c/o Dow AgroSciences LLC has submitted the following summary of information, data, and arguments in support of their pesticide petition. This summary was prepared by Mycogen Seeds c/o Dow AgroSciences LLC 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
B.t. Cry34/35Ab1 inductively coupled plasma (ICP) is expressed in corn plants to provide protection from key coleopteran insect pests such as the western corn rootworm. B.t. Cry34/35Ab1 transgenic plants are derived from transformation events that contain the insecticidal genes via a plasmid insert. The B.t. Cry34/35Ab1 ICP poses no foreseeable risks to non-target organisms including mammals, birds, fish, beneficial insects, and earthworms. B.t. Cry34/35Ab1-protected field corn provides growers with a highly efficacious tool for controlling important insect pests in corn in a manner that is fully compatible with integrated pest management practices.
B. Product Identity/Chemistry
Identity of the pesticide and corresponding residues. The Cry34Ab1 and Cry35Ab1 genes were isolated from Bacillus thuringiensis strain PS149B1 and modified before insertion into corn plants. The Cry34/35Ab1 ICP has been adequately characterized. Several safety studies were conducted using microbially produced test substances that contained 54% of the Cry34Ab1 (14 kDa) protein and 37% of the Cry35Ab1 (44 kDa) protein. Studies conducted to establish the equivalence of the Cry34/35Ab1 ICP obtained from corn or from a microbial source demonstrate that the materials are similar with respect to molecular weight, immunoreactivity, lack of post-translational modification (glycosylation) N-terminal amino acid sequence, and spectrum of bioactivity.
A qualitative analytical method (lateral flow immunoassay) for the detection of the Cry34Ab1 (14 kDa) protein has been submitted; master record identification number ((MRID) #45383401). Quantitative analytical methods enzyme linked immunosorbent assay (ELISA) for the detection of Cry34Ab1 and detection of Cry35Ab1 have been submitted (MRID #45833201).
C. Mammalian Toxicological Profile
Cry proteins have been deployed as safe and effective pest control agents in microbial Bacillus thuringiensis formulations for almost 40 years. There are currently 180 registered microbial Bacillus thuringiensis products in the United States for use in agriculture, forestry, and vector control. The numerous toxicology studies conducted with these microbial products show no significant adverse effects, and demonstrate that the products are practically non-toxic to mammals. An exemption from the requirement of a tolerance has been in place for these products since at least 1971 (40 CFR 180.1011).
Toxicology studies conducted to determine the toxicity of Cry34/35Ab1 ICP demonstrated that the proteins have very low toxicity. The acute oral lethal dose (LD)50 of Cry34Ab1 (14 kDa) is greater than 5,000 milligrams/kilogram (mg/kg), and at 54% purity, the acute LD50 for pure protein is greater than 2,700 mg/kg. The acute oral LD50 of Cry35Ab1 (44 kDa) is greater than 5,000 mg/kg, and at 37% purity, the acute LD50 for pure protein is greater than 1,850 mg/kg in male mice when the proteins were tested individually. When tested as a mixture (1:3 molar ratio of Cry34Ab1:Cry35Ab1 proteins), the acute oral LD50 of Cry34/35Ab1 proteins in male and female mice is greater than 5,000 mg/kg, and greater than 2,000 mg/kg of an equimolar (1:3) mixture of pure proteins.
In in vitro studies, Cry34/35Ab1 ICP exhibited a high rate of digestibility under simulated gastric conditions (referred to as SGF) in the presence of pepsin. The Cry34Ab1(14 kDa protein) was greater than 90% digested in SGF 6.2 minutes. The Cry35Ab1 (44 kDa protein) was greater than 97% digested in less than 5 minutes. Also, thermolability testing results showed that the ICP was deactivated following exposure to 60 °C, 75 C°, and 90 °C for 30 minutes. A search of relevant data bases indicated that the amino acid sequences of the Cry34/35Ab1 ICP exhibit no significant homology to the sequences of known protein allergens. Thus, Cry34/35Ab1 ICP is highly unlikely to exhibit an allergic response.
The genetic material necessary for the production of the Cry34/35Ab1 ICP is nucleic acid deoxyribonucleic acid (DNA) which is common to all forms of plant and animal life. There are no known instances where nucleic acids have caused toxic effects as a result of dietary exposure.
Collectively, the available data on Cry34/35Ab1 ICP along with the safe use history of microbial Bacillus thuringiensis products establishes the safety of the plant-incorporated protectant B.t. Cry34/35Ab1 ICP and the genetic material necessary for its production in all raw agricultural commodities.
D. Aggregate Exposure
Dietary exposure. Because B.t. Cry34/35Ab1 ICP is expressed in minute quantities and is retained within the plant, there is virtually no potential for dermal or inhalation exposure to the protein. Significant dietary exposure to Cry34/35Ab1 ICP is unlikely to occur. Dietary exposures at very low levels, via ingestion of processed commodities, although, they may occur, are unlikely to be problematic because of the low toxicity and the high degree of digestibility of the protein. In addition, the protein is not likely to be present in drinking water because the protein is deployed in minute quantities within the plant, and studies demonstrate that Cry34/35Ab1 ICP is rapidly degraded in soil. In summary, the potential for significant aggregate exposure to Cry34/35Ab1 is highly unlikely.
E. Cumulative Exposure
Common modes of toxicity are not relevant to consideration of the cumulative exposure to B.t. Cry34/35Ab1 ICP. The product has demonstrated low toxicity, and these effects do not appear to be cumulative with any other known compounds.
F. Safety Determination
1. U.S. population. The deployment of the product in minute quantities within the plant, the very low toxicity of the product, the lack of allergenic potential, and the high degree of digestibility of the proteins, are all factors in support of Mycogen/Dow AgroSciences' assertion that no significant risk is posed by exposure of the U.S. population to B.t. Cry34/35Ab1 ICP.
2. Infants and children. Non-dietary exposure to infants and children are not anticipated, due to the proposed use pattern of the product. Due to the very low toxicity of the product, the lack of allergenic potential, and the high degree of digestibility of the proteins, dietary exposure is anticipated to be at very low levels and is not anticipated to pose any harm to infants and children.
G. Effects on the Immune and Endocrine Systems
Given the high degree of digestibility of the Cry34/35Ab1 ICP, no chronic effects are expected. Cry34/35Ab1 ICP, or metabolites of the ICP are not known to, or are expected to have any effect on the immune or endocrine systems. Proteins in general are not carcinogenic, therefore, no carcinogenic risk is associated with the Cry34/35Ab1 ICP.
H. Existing Tolerances
A temporary exemption from the requirement of a tolerance is in effect through April 30, 2006.
I. International Tolerances
No Codex maximum residue levels exists for the plant-incorporated protectant modified Cry3A Bacillus thuringiensis protein and the genetic material necessary for its production in corn.
