i. Identify the document by docket ID number and other identifying Start Printed Page 5078information (subject heading, Federal Register date and page number).

ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.

iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

iv. Describe any assumptions and provide any technical information and/or data that you used.

v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified.

II. Registration Applications

EPA received an application as follows to register a pesticide product containing an active ingredient not included in any previously registered products. Pursuant to the provision of section 3(c)(4) of FIFRA, EPA is hereby providing notice of receipt of the application and opportunity to comment.

File Symbol: 53575-GA. Applicant: Pacific Biocontrol Corporation, 575 Viewridge Dr., Angwin, CA 94508. Product name: Isomate-EGVM mating disruptor pheromone (E,Z)-7,9-Dodecadien-1-yl acetate at 75.68%. Proposed classification/Use: None.

III. Background Information

The European Grape Vine moth (EGVM), Lobesia botrana, is a Lepidopteran pest that poses a risk of serious harm to vineyards. The EGVM is established in many parts of the world, but, has not previously been observed in the United States. Recently, the EGVM has been observed in the Napa Valley of northern California. The EGVM can feed on both the flower and the fruit of the grapevine. If the moth attacks mature grape clusters, the berries can become further damaged through infection by the fungus botrytis - a condition known as bunch rot. In 2009, Napa Valley winegrape growers suffered serious crop loss and damage from EGVM. Approximately 30 properties have been officially identified as having the pest present, and it is believed that the pest will be found on many more properties once delimitation trapping is conducted this spring. As a sustainable agriculture community, registration of a pheromone-based product is of importance to the Napa Valley winegrape growers and other affected communities in order to provide effective, sustainable, and low risk alternatives to traditional pesticides.

The subject active ingredient is a synthetic biochemical that is structurally similar to and mimics the naturally occurring pheromone produced by the female EGVM to attract males for mating. This pheromone is one of a group of straight-chain lepidopteran pheromones (SCLPs) for which EPA has previously conducted an aggregate risk assessments. The active ingredient will mitigate the effects of the EGVM by disrupting the normal mating cycle of the EGVM. The pheromone will be contained in a twist-tie dispenser that consists of a polyethylene plastic tube parallel to an associated aluminum wire within the field. It will be applied by hand directly on the plant or trellis wires. Each twist-tie dispenser slowly releases infinitesimal amounts of pheromone into the atmosphere. The pheromone slowly diffuses from the inside of the tube to the surface where it volatilizes in microgram amounts. This formulation is not randomly distributed by a mechanical device, nor is it sprayed into the air.

A. What are pheromones?

Pheromones are natural chemicals emitted by insects that mediate communications between individuals of the same species. Pheromones serve a number of functions including identifying the location of food sources, alarming other individuals about potential dangers, and locating potential mates. Pheromones are ubiquitous in the environment, and are not considered to be air pollutants.

EPA has registered many products containing SCLPs. The Agency has compiled a substantial database on SCLPs and has assessed the risks of this class of compounds to human health and the environment. SCLPs exhibit negligible toxicity in animal testing; have no effects on non-target species; and are used at extremely low rates (application rates of SCLPs do not exceed 150 grams active ingredient/acre/year). Because the effects of SCLPs are highly species specific, and given their low application rates, risks to human health are negligible. In addition, EPA concludes that there is no likelihood of adverse effects to non-target organisms. SCLPs are exempt from the requirement of a tolerance in or on all raw agricultural commodities when applied to growing crops at a rate not to exceed 150 grams of active ingredient/acre (40 CFR 180.1153). EPA has determined that there is a certainty of no harm from consumption of food containing residues of SCLPs.

B. What is Isomate-EGVM?

The application before the Agency is for “Isomate-EGVM,” an end-use product (EP) containing 94% of active ingredient, which is the SCLP that is chemically similar to the pheromone produced naturally by the European Grapevine Moth - and which has a similar physiologic effect. In general, pheromones are easily broken down by UV light and oxidation, and do not remain long in the environment. But, to be effective, the Isomate-EGVM must last long enough to effectively act on the target pest's population within the orchards where they are used. Inert ingredients are therefore added as stabilizers to protect the longevity of the pheromone. Isomate-EGVM contains two inert ingredients, BHT and bumetrizole. BHT is an antioxidant and bumetrizole functions as a UV stabilizer. BHT is approved by the FDA as a food additive permitted for direct addition to food for human consumption, and is present in a wide array of food items. Bumetrizole is also approved by the FDA as a stabilizer in polymers used in producing, manufacturing, packaging, processing, and transporting food. In addition, the NOP (National Organic Program) has approved both of these ingredients for organic uses involving twist-tie dispensers.

C. EPA’s Proposed Action

Pursuant to FIFRA Section 3(c)(4), EPA is providing notice of, and the opportunity to comment on, the receipt of an application for registration for the pesticide product Isomate-EGVM. In addition, EPA is providing advanced notice of OPP's preliminary risk assessment on Isomate-EGVM. EPA has been informed by USDA’s Animal Plant Health Inspection Service (APHIS) that vineyards located in Sonoma and Napa counties in California have become infested with EGVM. The moth is currently in diapause. APHIS is concerned that an active and severe infestation may begin when the moths begins to emerge from diapause in late February. APHIS has requested expedited consideration of the Isomate-EGVM registration application so that growers will be able to immediately begin to use this product for mating disruption efforts when the insects emerge. Based upon EPA's risk assessment for SCLPs, including the EGVM pheromone, EPA believes that registration of Isomate-EGVM will not cause harm to humans and will not Start Printed Page 5079cause unreasonable adverse effects on the environment particularly given the fact that the product, when applied, volatizes when released.
