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 emerged foxtail, fall panicum, and barnyardgrass that is less than 2 inches tall and provides short-term residual control if activated by rainfall or sprinkler irrigation. Apply to field corn that will have a lay-by cultivation 10 or more days after Basis Herbicide application. Apply when corn is in the spike to 4-leaf (V2, or 2 leaf collars visible) stage (approximately (0.5 to 6 inches tall). Grass weeds must be less than 2 inches tall at treatment. Apply with NIS or COC and with UAN or spray-grade AMS. If dicamba is added do not use COC. Do not tank mix with Basagran, Laddock S-12, Accent, Beacon Herbicide, or other ALS-inhibiting herbicides. Do not apply to corn that was treated with Counter 15G or 20CR in-furrow. See label for insecticide compatibility, sprayer cleanup, rotational cropping, and feeding restrictions. Rotate to wheat after 4 months and sorghum or sunflower after 10 months. Follow label directions.
