Weed control in soybeans is a summer long effort. In early July, we made our 3rd pass with the sprayer. The first pass was right after planting and consisted of a herbicide to burn down existing weeds as well as one that gave us about 1 month of control for emerging weeds. The second pass was similar but using chemicals with different modes of action to circumvent weeds becoming resistant to the few chemicals we have left. For the 3rd and final pass we use Roundup and a grass control herbicide. The grass control herbicide controls the volunteer corn. The Roundup will control some weeds that aren’t resistant. We will use hand weeding as a follow up to control weeds that are Roundup resistant.
