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
Permit Herbicide can be applied to corn over the top or with drop nozzles from the spike through lay-bay stage of growth for control of many broadleaf weeds and suppression of yellow nutsedge. Use 0.25 to 0.5% v/v NIS or COC at 1% v/v. To enhance pigweed and morning glory control, an herbicide with improved activity on these species should be added to the mix.
