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.
