Growers should start with a clean seedbed by either using tillage and/or a burndown herbicide application to control emerged weeds. In areas with glyphosate-resistant weeds, it is recommended that an at-planting tankmix include glufosinate, plus a residual herbicide such as diuron, fluometron, or fomesafen at labeled rates.
For early in-season weed control, glyphosate may be tankmixed with an acetanilide herbicide or an encapsulated acetochlor herbicide such as Warrant® Herbicide. Other options are provided in the box below. Always read and follow product labels and application directions. Be sure to scout fields before and after any in-crop herbicide application to monitor herbicide efficacy or potential resistant weed populations.
Burndown applications play a critical role in season-long weed management.
