Soybean weed control

Weed

One of the few weeds.

Spraying Right Boom ViewWeed 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.

Pre-emerge weed control in corn

An area with no pre-emerge herbicide.

Early in spring, pre-emerge herbicide was applied to our corn fields. This picture shows how necessary that is. These 12 rows are in a location that we cannot get to with our field sprayer and no herbicide was applied early. You can see the weed pressure that exists in this part of the field. Those weeds will quickly rob the corn of it’s full yield potential.

Post emerge spraying will clean up weeds that come through the early application. Later we will cultivate these fields and build ridges in the corn that will serve as the seedbed for next year’s soybeans.
