Thoughts on GM Alfalfa

As we were bouncing around in the truck today the subject of GM crops came up. Particularly GM Alfalfa. I got an earful from a hay growers perspective and while I don't agree, his take bears discussion. He says that the GM crop will save $30 an acre in pesticides, another $50 an acre in cover cropping, and $20 or more in herbicides. $100 an acre doesn't sound like much but when you plant hundreds of acres it appeals to ones bottom line. I asked him what it would take for him to stay with conventional seed and his response was "Buy the field before its planted". So that's what several of us are going to do. He also said that the majority of the Imperial Valley is going with the GM crop. I asked "what about drift?" The response was "It's harvested pre-bloom so there is no drift". Huh? Then what are those purple things in the hay bales? It is sad that these guys can't see the hazards of GM crops. I really wish there was a way to make them see the disaster they are putting in the ground. What do you think?
