EFSA confirms neonicotinoid spray risk to bees
Neonicotinoid insecticides applied as foliar sprays pose a risk to bees, says the European Food Safety Authority (EFSA). Its conclusions follow assessments on the risks to bees from clothianidin, imidacloprid and thiamethoxam. For all authorised foliar uses, high risks were identified or could not be excluded, or the risk assessment could not be finalised due to lack of data. The EFSA suggests that some cases could be helped by risk mitigation measures, such as preventing weeds in fields from flowering, and reducing drift in field margins and adjacent crops.
