A weed scientist says the dry weather is forcing many farmers to apply post-emergence herbicides a lot earlier than they had planned.
Dr. Rodrigo Werle with the University of Wisconsin says, “The topsoil as been really dry meaning that the pre-herbicides are not doing what they are supposed to be doing right now.”
Werle tells Brownfield the pre-emergence herbicides might be failing to kill weeds because they needed moisture to activate, and because it is dry, the weeds have the advantage.
