In order to minimize the entry of pesticides into surface water within the scope of the application, conditions are imposed when a plant protection product is approved, as well as distance requirements .
Distance requirements define the minimum distances to surface waters that must be observed when using pesticides to protect aquatic organisms.
The minimum distance (standard distance) is calculated and set as part of the approval for each plant protection product due to its toxicity to aquatic organisms, taking into account the application rate and the crop. Failure to comply with the requirements leads to the imposition of fines and also to reductions in funding due to breaches of good professional practice .
