field trial
Test conducted on crops to establish how much pesticide remains after normal farming practices and for how long pesticides and their residues persist in the crops. The test results are used to inform rules about permitted amounts of pesticide residues in foodstuffs
In food safety, a field trial for pesticides is an experiment where crops are grown under real agricultural conditions to test how a pesticide behaves. These trials show how much of the pesticide remains on or in the crop, how it breaks down over time, and whether it could accumulate in the environment or in food.
EFSA uses data from pesticide field trials to assess the safety of pesticide residues in food. By analysing the levels found in crops and combining this with information on how much of the food people eat, EFSA can determine whether exposure to the pesticide is within safe limits and decide if any measures are needed to protect public health..
