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: Grasshoppers, Grasshoppers
New and unique insecticide mode of action in corn: IRAC group 22, sodium channel blocker. CAUTION signal word. Provides alternative MOA for corn rootworm adults and other pests (especially lepidoptera) showing resistance to pyrethroids, organophosphates or carbamates in corn. Indoxacarb is a proinsecticide with low contact toxicity. It works by ingestion, so only pests feeding on treated foliage are affected. It has relatively little effect on beneficial arthropods which has been shown to reduce spider mite flaring associated with other insecticide treatments. REI is 12 hrs. PHI is 14 days grain and stover, 1 day for forage, fodder or silage. Make no more than 2 applications per crop.
