Size of the trial plots

Trial plots should be a minimum of 5 ha. Should this not be the case, testers should make sure that the treated crop represents a major nutritional source for the colonies of the test during the crop flowering period. Treated seeds or granules with the formulated product can be used as well. It should contain the highest dose recommended for field application. Should less attractive crops be used, specific attention should be put on assuring that exposure occurs.
