Location: Temperate Tree Fruit and Vegetable Research
2015 Annual Report
Objectives
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.
Approach
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 establish 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.
Progress Report
This is the first report for this project which began on August 3, 2015 and continues research from 0500-00007-093-00D, "Residue Analysis of Minor Use Pesticides". Please see this report for additional information.
This project helped growers access to new pesticide uses on minor crops. These new uses established safer alternatives to older chemicals which faced stiffer regulation and offered the potential for more environmental and health impact. The residue research completed also helped establish new controls for new threats to minor use crops.
In the portion of FY15 for which this project was active, residue data collection was completed for 2 pesticide projects with 36 crop samples from 9 different field sites.
It is anticipated in FY16 there will be residue data collection for 5 pesticide projects with approximately 50 different field sites for a total of 200 samples.
