The objective of OECD Test Guidelines for the pesticide residue chemistry is to assess pesticide exposure by identifying these residues in food or animal feedstuffs for purposes of dietary risk assessment and setting Maximum Residue Levels. They have been developed and are based on guidelines in...

Crop field trials are conducted to determine the magnitude of the pesticide residue in or on raw agricultural commodities, including feed items, and should be designed to reflect pesticide use patterns that lead to the highest possible residues. Objectives of crop field trials are to: (1)...

This Test Guideline describes how to plan and carry out processing studies, i.e. determine residue levels in primary processed commodities following pesticide application on raw agriculture commodities (RAC) under conditions likely to lead to maximum residues. It provides the distribution of...

Metabolism in Livestock studies are used to determine the qualitative and quantitative metabolism and/or degradation of the active ingredient resulting from pesticide use in feedstuffs, direct application to livestock, or premise treatment. The studies provide an estimate of total residues in...

The aim of these studies is to demonstrate the time period for which stability has been shown in representative commodities from crops. Freezer storage stability studies should include sufficient starting material and should have a sufficiently high concentration of residue to allow for any...

Metabolism in rotational crops studies are conducted to determine the nature and amount of pesticide residue uptake in rotational crops that are used as human food or as livestock feed. The provide an estimate of total radioactive residues in the various raw agricultural commodities (RACs);...

The residues in Livestock studies are conducted in order to quantify levels of residues in meat, milk, eggs and edible meat by-products following the use of a pesticide product. The situations to which such studies apply include application of a pesticide to raw agricultural commodities (RACs),...

Studies of Metabolism in Crops are used to elucidate the degradation pathway of the active ingredient and require the identification of the metabolism and/or degradation products when a pesticide is applied to a crop directly or indirectly. A Metabolism in Crops study should be submitted for...
