"Neonicotinamides or "neonics" (of which clothianidin is just one example) are the new weapon of choice by many large crop farmers and by some domestic gardeners, too. They affect the whole system of the plant and are highly toxic to bees and other insects feeding on the pollen and nectar."
Farmers, (and the UK government) are against the banning of this stuff.
I remember the fight they put up against the DDT ban.
