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
Carfentrazone helps control black nightshade, velvetleaf, lambsquarter, pigweed, and morningglory when applied to actively growing plants 1 to 4 inches tall. Can be broadcast applied to corn with up to 8 leaf collars. For corn from 9 to 14 leaf collars, apply with drop nozzles. Always apply with NIS at 0.25% v/v. Substituting 1% v/v COC is permissible for very dry soil conditions, but leaf speckling on treated corn may increase. Can be tank mixed with other postemergence corn herbicides to broaden the weed spectrum and increase the level of control. For tank mixes, follow application and rotation guidelines of the more restrictive partner. Thorough and uniform spray coverage is needed for best results. Any crop can be planted after 30 days following application. Follow label directions.
