Comments and limitations

Valor XLT is a premix of 10.3% chlorimuron (Classic) and 30% flumioxazin (Valor). Recommended mainly for eastern Kansas. Provides residual and burndown control of many broadleaf weeds.Can be applied preplant in the fall or spring or preemergence until 3 days after planting. If emerged weeds are present at the time of treatment, add COC to enhance foliar activity. The addition of glyphosate and/or 2,4-D is recommended for more broad-spectrum burndown weed control. If the soil pH is greater than 6.8, do not use more than 2.5 oz/acre of Valor XLT. Do not apply Valor XLT in fields treated with products containing flufenacet, alachlor, metolachlor, or dimethenamid. Do not allow grazing in treated fields or harvest for hay or forage. Do not rotate to wheat for 4 months; field corn, cotton, or sorghum for 10 months; alfalfa for 12 months; sunflower for 18 months; or canola for 30 months after application.

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!
