We have experience with one at the moment, because the corns went in first. They're using the same type of poison on soybeans, and there are 22 different brand names that they use on these poisons. It's an neonicotinoid or an imidacloprid, and they break down into more deadly types of poison. From what we've read and all the information we have, they change.
There's a straight indication that these are the ones that are killing things off. All of us and most of the beekeepers have noticed over the last few years that there's been some sort of a slight kill-off, but we couldn't trace it to any place and didn't know what it was from. It wouldn't be that there'd be the numbers of bees dying off, but you'd see dead bees in front of the hive, and a hive doesn't want dead bees in front of it. It's just a natural defence mechanism that it has. It wants to clear everything out of the front of the hive so that predators don't know where it is. You'd see that in a tree or something like that in the natural circumstance. They would make sure of that. They don't want dead bees around the hive, because those would give an indication of where they're living. So they have a natural defence mechanism that way.
All I can say is that as far as we know, it is connected to the poison. There was a webinar put on by the U.S. I can't remember the name of the state that put it out. Was it Purdue?
