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
Arthropod: European Corn Borer, European Corn borer
Organophosphate insecticide; signal word on label: CAUTION. For corn borer management ground application is preferred to aerial application. Do not exceed two applications per season. REI is 24 hours. Preharvest intervals are the same as Chlorpyrifos 4E. The label has recently been revised, so read carefully before use. Label changes include requiring a dust filtering mask for loaders and applicators, deletion of use on popcorn, elimination of band application and pre-plant broadcast application and a limit on the maximum seasonal applications of chlorpyrifos 15G to two (one atplant soil application and one foliar application) or no more than three applications of products containing chlorpyrifos per season. Supplemental labels allow harvest after 21 days for rates below 1 lb. a.i./ acre.
