Hi Bob and all

Have you found, in your searches, references to imidacloprid half  
life.  I believe it is quite long.  I remember reports from PEI that  
measurable amounts of imidacloprid showed up in the following year  
cover crop after being used on potatoes.  Year three potato crop was  
again treated with residuals from year one remaining.  The bees get  
nothing from the potatoes but do forage on the cover crops and verges.
