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: Sorghum
Application type: Postemergence
Apply Kochiavore for broadleaf weed control to sorghum from the V4 to V8 stage. Drop nozzles should be used when treating at the V8 to pre-boot stage. DO NOT tank mix with atrazine, crop oils, or other adjuvants such as NIS. Some sorghum hybrids are sensitive to 2,4-D and will be injured. Consult your seed dealer. Do not allow the crop to be used as fodder, forage, or grazing for 45 days following application. Do not harvest within 70 days of the application. Only one application is allowed per growing season.
