Re: cranberry pollination
I don't know anything about cranberry pollination in WI, Here in NY I pollinate about 80 acres of crans. I haven't noticed any problems w/ pesticides.
I get my cols into the crans soon after they come out of apple pollination and leave them there all Summer. I don't think they make anything in the way of honey from the crans. Not enuf for me to notice.
Actually, not that I spend a lot of time looking, I haven't seen bees working crans. But, the difference between them being there during pollination time and not was quite evident when one year I didn't have them there and the next year when I did and there was considerablly higher per acre berry production.
I get $50.00/cols. They may get more in WI.
