Research Project: Residue Analysis of Minor Use Pesticides

Location: Temperate Tree Fruit and Vegetable Research

2013 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. Replacing 0500-00007-082-00D (7/2010), 0500-00007-067-00D (11/2005), and 0500-00007-051-00D (06/2003).

3. Progress Report:
In FY13, residue data collection completed for 5 pesticide projects with 178 crop samples from 25 different field sites. There are currently 3 pesticide projects which should be completed prior to October 1. These projects total 72 crop samples from 18 different field trials. It is anticipated in FY14 there will be residue data collection for 4 pesticide projects with approximately 30 different field sites for a total of 175 samples.

4. Accomplishments
1. Food quality and pesticides use in crops. Because of the Food Quality Protection Act (FQPA), pesticides for use on minor crops are increasingly being removed from the marketplace. At Yakima Agricultural Research Laboratory Inter-Regional Project Number 4 unit, Wapato, Washington, we assist in obtaining minor use and specialty use pesticide clearances and assist in maintenance of current registrations by analyzing crops for pesticide residues. This past year, we completed the residue data collection for 8 pesticide projects with 250 crop samples from a total of 43 different field sites. This provided data for 8 separate pesticide label registration proposals, which will eventually be sent on to the Environmental Protection Agency, making up part of an overall project aimed at giving farmers market access to targeted pesticides for use on their minor crops.
