Last week we attended the Illinois Crop Management program in Springfield. They seemed to save the best speaker for last. Dr. Hager discussed weed control in the resistance era. He continues to call for multiple modes of action in the same application. He showed us why herbicide rotations are not really effective in keeping resistance at bay. His discussion of Palmer Amaranth took up a big part of the program. He says we need to have zero tolerance. That means if soybeans are too tangled to walk through, you need to get in the truck or 4 wheeler and go get the plants. The destruction of crop will be minor in comparison to the problems created by the Palmer amaranth. Evena few weeds should be removed. More on resistance here.
