Chemical selector
The Pesticide Selector includes suggestions for chemical control of pests in Kansas crops, which are provided by K-State Research and Extension, and may not be relevant for states other than Kansas. We will continue to expand this tool for help in selecting other types of agricultural chemicals, and for other states. Contact the myFields Team if you are interested in contributing content!

Crop type: Corn
Application type: Postemergence
Controls 4 to 12-inch shattercane, 8 to 16-inch rhizome johnsongrass, and many annual broadleaf weeds 1 to 4 inches tall. Apply to approved field corn hybrids at 4 to 20-inch height or postdirected between the rows for corn from 20-inch height to tasseling. Apply with NIS or COC. Up to 1 gal/acre of UAN can be added to improve control of velvetleaf and rhizome johnsongrass. Do not apply to corn treated with Counter 15G insecticide. Do not apply in irrigation water. Half rates of Beacon Herbicide and Accent can be applied together as a sequential treatment to a preemergence grass-control herbicide. Can be tank mixed with dicamba, dicamba plus atrazine premix, bromoxynil plus atrazine premix, or 2,4-D for enhanced broadleaf weed control, but then do not use COC adjuvant. Can be tank mixed with pendimethalin for enhanced residual grass control. See label for insecticide compatibility, sprayer cleanup, subsequent cropping, feeding restrictions, and other guidelines. Follow label directions.
