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: Preplant or Preemergence
These herbicides are restricted-use pesticides. The addition of atrazine will enhance annual grass and broadleaf weed control. The ratio of acetochlor to atrazine varies in the products named. For sensitive watersheds, see K-State Research and Extension publication MF-2208 for atrazine best management practices. Follow atrazine rate limits and label directions. No-Till: If applied more than 30 days before planting, use split applications of 60% early preplant followed by 40% at planting. For single applications, apply within 30 days preplant up to planting time. Can be tank mixed with atrazine, Hornet WDG Broadleaf Blend Herbicide, Gramoxone SL, glyphosate, dicamba, or 2,4-D and adjuvants to control emerged weeds. Follow atrazine rate limits and label directions.
These herbicides are restricted-use pesticides. These formulations are used by growers who want to reduce rates of soil-applied atrazine. Formulations vary in their ratio of acetochlor to atrazine, so follow label directions.
