That ' s a terrible idea . I hope they don ' t do it all . The EU banned imidacloprid in 2014 , and 2015 has seen the instant resurgence of flea beetles and their larva in UK canola . The only approved solution is spraying Pyrethrin in autumn , so up till then , the famers are basically screwed . The rapeseed production has fallen by about 11 % since the introduction of the ban . At the same time , use of Pyrethrin and other , far more dangerous substances is way up . At the same time , beehive numbers have remained steady for decades . Think about it . Banning an effective tool that can be used safely only leads to the increased use of other tools , with far worse effects . It makes sense to ban substances that have better , saver alternatives like DDT and Endosulfan . It does NOT make sense to ban effective tools when there is no replacement . Yes , Imidacloprid can be dangerous , but not AS DANGEROUS as the alternatives , which don ' t even work very well .
