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: Soybean
Application type: Preplant or Preemergence
Apply in the fall, preplant, or preemergence to soybean. Add COC to enhance burndown activity on emerged weeds in no-till. Controls several broadleaf weeds, including pigweeds and black nightshade. Tank mixes of Valor with flufenacet, metolachlor, dimethenamid, or alachlor products may result in severe soybean injury. Do not rotate to wheat for 1 month or to alfalfa or oat for 8 months after application.
