Research Project: Residue Analysis of Minor Use Pesticides

Location: Temperate Tree Fruit and Vegetable Research

2011 Annual Report

1a. Objectives (from AD-416)
Determine the amount, persistence, and fate of pest insect control chemicals and their toxic breakdown products in minor agricultural crops in the United States. Provide data in support of registration/re-registration petitions to EPA through IR-4 Minor Use Program.

1b. Approach (from AD-416)
Minor agricutural crops treated with insect control chemicals such as pyrethroids, organophosphates and carbamates will be chemically analyzed to determine the amount, persistence and distribution of these chemicals and their breakdown products. The data collected will be forwarded through designated channels and used to estabish tolerances and obtain registration for the use of these chemicals on minor crops. Also, new efficient procedures for the extraction, cleanup, and determination of residues of these pesticides in crops will be developed to more rapidly expedite these registration processes.

3. Progress Report
This project research facilitates the registration of pesticides for use to control pests on minor crops. In FY11, residue data collection completed for 3 pesticide projects with 105 crop samples from 21 different field sites. There is currently one pesticide project being analyzed which should be completed prior to October 1. This project totals 71 crop samples from 15 different field trials. It is anticipated in FY12 there will be residue data collection for 5 pesticide projects with approximately 40 different field sites for a total of 175 samples.
