4.3.5.2.5.1. Crops planted in the trial plots

In order to increase the likelihood that bees will forage in treated plots, crops attractive to bees should be used. Special attention should be put on the nutritional value of the pollen of the chosen crop. Rich pollens as that of oilseed rape or Phacelia may mask the effects of the exposure to the pesticide. Ideally, an attractive crop with pollen of lower nutritional value would better evidence any toxicological problems (e.g. sunflower). For regulatory purposes, the crop for which the authorisation is to be requested should be used.
