Love the podcast, listener for a few years. I wonder if you know anything about an issue I have, or suggestions for where to get info. My hives are on a non-profit urban farm property that abuts city owned property. The city is planning to spray herbicides (aminopyralid, clopyralid, aminocyclopyrachlor, and imazapyr) on thistles in the area. Should I be worried about my bees? Is thre anything I can do to mitigate damage?
