The Department of Agriculture, specifically the Animal and Plant Health Inspection Service (APHIS), is seeking proposals for product chemistry registration studies of the pesticide "Spinosad Fruit Fly Bait." The primary objective is to conduct a series of chemical studies in compliance with the Environmental Protection Agency (EPA) guidelines and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Good Laboratory Practices (GLPs) to support future pesticide registration applications. These studies will include characterizing the Spinosad reference standard, validating analytical methods, and assessing various chemical properties such as storage stability and corrosion characteristics. Interested vendors must submit complete quotes and required documentation by the specified deadlines, adhering to FAR regulations and USDA policies. For further inquiries, potential contractors can contact Latisha Hollman at latisha.a.hollman@usda.gov.
