Pesticides Commercial Applicator Application. Pesticide residue compliance monitoring programmes analyse individual foods ‘as purchased’ (i.e. bananas, including skin; meat, raw, etc.). Because a smaller range of foods are generally targeted, sample numbers per commodity are generally more robust than in a TDS. Any pesticide residues found are checked for compliance with the MRL for that commodity, which has been set to reflect GAP., Pesticide Application Protocol Ventura County Application Protocol for Pesticides, Fertilizers, and Herbicides (February 2014).
