 Furthermore, the German authorities explicitly required the use of additional sticker to ensure the pesticides adhere to the seeds.In June 2008, BVL concluded that “the treatment of rapeseed with clothianidin containing plant protection products does not put bee colonies at risk” but offered additional recommendations to better control dust and discouraging planting on windy days or using pneumatic seeding equipment that discharges air upward.In 2009, BVL decided to continue to suspend authorization for the use of clothianidin on corn, citing unanswered questions that remained about potential exposure of bees and other pollinators to neonicotinoid pesticides.
