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)quantify the expected range of residue(s) in crop commodities following treatment according to the proposed or established good agricultural practice; (2)determine, when appropriate, the rate of decline of the residue(s) of plant protection product(s) on commodities of interest; (3)determine residue values such as the "Supervised Trial Median Residue" and "Highest Residue" for conducting dietary risk assessment; and (4)derive maximum residue limits (MRLs). This Test Guideline requires one sample from treated plots at each sampling interval for crops that have eight or more crop field trials. The test substance(s) should be stored under appropriate conditions for the study duration and applied soon after preparation or mixing. Test substance applications should not be made in strong wind, during rain or when rainfall is expected shortly after application. For all applications, the application rate should be expressed in terms of amount of product and/or active ingredient per unit area. At the end of each crop field trial, the (stored) samples are analysed for residue level (expressed for example in mg/kg).
This Test Guideline describes a method to determine the amount of pesticide residues which may be accumulated into rotational crops via soil uptake following realistic agricultural practices. These data may be used to establish crop rotation ...
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 ...
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 ...
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 ...

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 ...
This Test Guideline describes a method conducted as model studies to predict the degradation pathway of the active ingredient under hydrolytic conditions, to identify the degradation products, and to determine the relative amount of degradation ...
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 ...
