Good Agricultural Practices(GAPs) Western Regions Pesticide Meeting May 2010
Good Agricultural Practices (GAPs) • Developed by registrants • Reviewed by EPA • Many GAPs on current labels • Presently as recommendations • GAPs will be mandatory • GAPs are chemical specific • Compliance with GAPs will be captured in FMP or post-application summary
Good Agricultural Practices (GAPs) • EPA believes GAPs: • Reduce the potential for bystander exposure to soil fumigants emissions. • Reduce the potential for handler exposure to soil fumigant emissions. • Reduce the potential for accidents. • Improve the efficacy of soil fumigation.
Good Agricultural Practices (GAPs) “The following GAPs must be followed during all fumigant applications.” “All measurements and documentation to ensure the mandatory GAPs are achieved must be recorded in the FMP and/or the post-application summary.”
Good Agricultural Practices (GAPs) • Soil preparation • good tilth • free of large clods • crop residue (if present) must not interfere with soil seal • Soil moisture • Appropriate for soil type • Determined using USDA’s Feel and Appearance method or an instrument Photos courtesy of USDA NRCS.
Good Agricultural Practices (GAPs) Soil Temperature • Maximum soil temperature is 90 degrees F, drip application exception • Location of soil temperature measurement varies
