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: Wheat
Application type: Postemergence
Controls Canada thistle, musk thistle, bull thistle, kochia, and wild buckwheat. Does not control most winter annual mustard species very well. Apply to small, actively growing weeds when wheat is grom the 3-leaf through the flag-leaf emergence stage of growth. Do not plant alfalfa or grain sorghum for 10.5 months; soybean, dry bean, or sunflower for 10.5 to 18 months; or cotton until at least 10.5 months, and conduct a field bioassay after WideMatch application.
