flumioxazin (Valor EZ)
Rate 0.0637 lb ai/a (2.0 oz/a Valor EZ)
Time Valor may be applied for burndown and residual control of broadleaf, and certain grass weeds, preplant in no-till and minimum till winter wheat production systems where the residue from the previous crop has not been incorporated into the soil. Valor applied at 2.0 oz/a will control or suppress annual bluegrass, Italian ryegrass and annual brome species. To completely control emerged weeds, Valor should be tank mixed with an appropriate burndown herbicide such as glyphosate. Plant winter wheat no sooner than 14 days after an application of Valor.
Remarks Winter wheat must be planted a minimum of 1 inch deep to minimize the risk of crop injury from this product.
Caution Do not apply more than 2.0 oz/a of Valor in a single application, and do not apply more 2.0 oz/a in a single growing season. Do not provide supplemental irrigation to the winter wheat between the emergence and spike growth stages because crop injury may occur. Do not graze winter wheat until it is 5 inches in height following a preplant Valor application.

saflufenacil (Sharpen powered by Kixor herbicide)
Rate 0.022-0.044 lb ai/a (1 to 2 oz/a Sharpen)
Time Sharpen may be applied for burndown and residual control of broadleaf weeds preplant surface, preplant incorporated or preemergence to winter wheat. Sequential applications may be made as needed prior to winter wheat emergence.
Remarks Sharpen does not control grass weed species. For optimum burndown efficacy use an MSO or COC adjuvant (1% v/v); when tank mixing with glyphosate the addition of AMS to the spray solution is recommended. Sharpen is rainfast 1 hour after application.
Caution See label for crop rotation intervals and emergency replanting intervals. Do not apply more than 4 oz/a (0.088 lb ai/a) of Sharpen per cropping season. Do not apply after winter wheat emergence, because crop injury will occur. Winter wheat may be fed, used as forage, or grazed 30 days after application.
