ACTION REQUESTED

	A preliminary assessment of available information on product chemistry
data associated with the biopesticide methyl anthranilate and its
biochemical products in support of the development of a Registration
Review Work Plan.

Introduction

The EPA has made the determination that there is adequate information
available on methyl anthranilate and does not foresee the need to
require additional data from products currently registered that contain
methyl anthranilate as the active ingredient.  Methyl anthranilate is
used as a bird repellent of various sites including golf courses and
airports. Methyl anthranilate products have been registered with the EPA
since 1994. Having a sweet aromatic odor, methyl anthranilate is found
naturally in some grape varieties and is commonly used as a flavoring
agent. Currently there are 10 active registrations containing methyl
anthranilate, consisting of one technical grade active ingredient
registration, eight end-use or manufacturing-use products, and one
experimental use permit. The registered technical contains 98.5% methyl
anthranilate and related impurities. According to 40 CFR §180.1143, the
Agency exempts methyl anthranilate from the requirement of a tolerance
in or on all food commodities, when used in accordance with good
agricultural practices.

Concerning the product chemistry of methyl anthranilate, all biochemical
pesticide data requirements for the technical grade active ingredient
are summarized in Tables 1 and 2

Product Chemistry Summary

The Agency has conducted a review of the available product chemistry
data and information.  These data are summarized below.
