The Department of Agriculture, specifically the Animal and Plant Health Inspection Service (APHIS), is seeking proposals for a FIFRA GLP Preliminary Analysis Study concerning a new source of biochar intended for use in pest control gas cartridge products. The primary objectives include validating analytical chemistry methods for characterizing the biochar, conducting a preliminary analysis on samples from five manufacturing batches, and preparing a final report in compliance with EPA standards, all while adhering to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This study is crucial for ensuring that the new biochar source meets regulatory requirements for pesticide registration, thereby supporting pest control initiatives with environmentally safe and locally sourced materials. Interested contractors should submit their proposals to Latisha Hollman at latisha.a.hollman@usda.gov, adhering to the specified guidelines and deadlines outlined in the Request for Proposal.
