I don't think they said this was total destruction of colonies, just a percentage kill.. this is the same senerio I had here last week after they planted corn around us. Strongest hives had the most dead bees, don't know any way to estimate how many bees were lost. I still would not say poncho was the culprit, after watching this video it would certainly be number one on the list..We have endless corn fields, last week 20 to 30 mile per hour winds from the south west, you could taste the dust in the air and count a half dozen tractors or dust columns to the south of us. I did not have total kill on any colonies, to date anyway, but the numbers dropped big time..We don't have a lot of cattle or livestock in this area anymore, but the few left have to be ingesting this stuff from pastures and hay that it settled on. Looks like a myriad of ways for it to get in our food chain, can not see how this is a good thing.. have 10 colonies at the present.dl
