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
Zemax Selective Herbicide may be applied preplant up to 14 days before planting or preemergence for grass and broadleaf weed control in field corn, seed corn, popcorn, and sweet corn. See postemergence section for Zemax Selective Herbicide postemergence on field and seed corn. Any adjuvants may be used to preplant or preemergence where corn has not emerged to increase burndown activity on existing weeds. Cereal crops (wheat, rye, barley, oats) may be planted 4.5 months following application. Soybeans may be planted the following spring. All corn or Concep-treated sorghum may be planted anytime. Glyphosate, Gramoxone SL, atrazine, and several other herbicides (see label) may be tank mixed with Zemax Selective Herbicide to improve burndown of existing weeds or improve the spectrum of broadleaf and grass weed control. Follow label directions.
