acording to etomoligist that makes his living with cotton farmers, unless the bee goes to consuming the green growing part of the plant there is nothing to hurt them unless it is sprayed on the cotton. My producers all give me 3 days notice befor the plane comes and they only spray if the stink bugs build up. but i always try to avoid corn that is late planted near by. that seed treatment is bad and I think it is one of my main problems
