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
Trivence is a premix containing 3.9% chlorimuron (Classic), 12.8% flumioxazin (Valor), and 44.6% metribuzin for burndown and residual control of broadleaf weeds. Recommended mainly for eastern Kansas; can be applied preplant in the fall or spring or preemergence until 3 days after planting. Do not apply more than 6 oz/a if soil pH is greater than 7.0. Apply with oil concentrate or NIS for control of emerged weeds. Often applied as a tank-mix with 2,4-D, glyphosate, or other herbicides for enhanced control of certain weed species. Do not apply in fields also treated preemergence with products containing flufenacet, alachlor, metolachlor, or dimethenamid. Do not rotate to wheat for 4 months; alfalfa or field corn for 10 months; sunflower, cotton, sorghum, or oats for 18 months; or canola for 30 months after application. Refer to label for crop rotation guidelines.
