2012 Annual Report 1a.Objectives (from AD-416): Provide efficacy, phytotoxicity and yield data and residue samples for analyses to support the registration or re-registration of minor use pesticides for the control or modification of behavior of pests through Interregional Project No. 4. Proposed research is relevant to the NP304 Action Plan, Component 2 - Protection of Agricultural and Horticultural Crops; Problem Statement 2b, Control. Relevance to Action Plan: 1b.Approach (from AD-416): Determine needs for minor use pesticides by consulting producers, processors, fieldmen, or their associations. Select pesticides for testing based on needs, efficacy, economics, and safety to the crop and its environment. Conduct studies on candidate pesticides in the field, nursery or greenhouse to obtain efficacy, phytotoxicity and yield data, and residue samples for analyses in accordance with protocols, standard operating procedures, and good laboratory practices. 3.Progress Report: This project relates to NP 304 2B, Protection of Agricultural and Horticultural Crops, Biology and Ecology of Pests and Natural Enemies, because the work facilitates the registration of pesticides for use to control pests on minor crops. In FY2012, 15 GLP food use trials and 9 non-food use trials of pesticide were completed. In support of petitions submitted by IR-4 to the Environmental Protection Agency (EPA) for the registration of pesticides on minor crops, in FY 2012, 15 Good Laboratory Practices (GLP) food use trials and 12 non-food use trials were completed. 4.Accomplishments 1. Minor use pesticide registration on crops. This research was done in support of petitions by the Insect Resistance (IR-4) Program to the Environmental Protection Agency (EPA) for the registration of pesticides on minor crops and ornamentals. IR-4 researchers at the USDA-ARS Yakima Agricultural Research Laboratory in Wapato, WA, conducted 73 Good Laboratory Practices (GLP) food use trials on vegetable crops, 14 trials on tree fruit crops, and 5 trials on forage crops. Non-GLP research consisted of 265 trials on ornamentals. This program ensures the safety of pesticides used on minor crops and ornamentals for growers and consumers across the United States.
