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: Sorghum
Application type: Postemergence
Controls or suppresses many broadleaf weed species. Usually used following a foundation application of Dual- or Bicep-type herbicide. Apply over-the-top to sorghum at least 5 inches tall. Refer to label for weed size limitations. If applied alone or tank mixed with atrazine, add COC at 1 qt/acre. Also add 2 to 4 qt/acre UAN if velvetleaf is targeted. If tank mixed with 2,4-D, dicamba, or liquid formulations of bromoxynil, add NIS instead of COC. There are no restrictions for rotation to wheat. Sunflower and soybean are very sensitive to Peak carryover. See label for rotation restrictions that differ by field location, rate of Peak applied, and soil pH.
