Expanded pre-emergence label for Monsanto’s Warrant herbicide

Cotton and soybean farmers have a new pre-emerge tool for residual weed control. Warrant® Herbicide (active ingredient: acetochlor) is now labeled for pre-emergence use. The new, expanded label for Warrant Herbicide will now help to provide farmers the flexibility to manage small seeded grasses and broadleaf weeds, as well as tough-to-control weeds like Palmer amaranth and tall waterhemp in either a pre- or post-emergence application.

"Results from on farm trials over the last three years have been extremely positive, with excellent crop safety and strong residual weed control when applied pre-emerge," says Tyler Hackstadt, selective chemistry marketing lead for Monsanto. “This label expansion for Warrant Herbicide will offer farmers and retailers increased flexibility with pre-emerge and post-emerge applications. Warrant can be applied at 1.25-4 quarts per acre (2.5-4 pints) pre-plant, at-planting or pre-emerge up to R2 in soybeans and through first flower in cotton. The formulation is the same. The only change is a newly expanded label that will include pre- and post-emergence use.”

Warrant Herbicide provides residual control of grasses and small seeded broadleaf weeds, including foxtails, lambsquarters, Palmer pigweed, and waterhemp. Warrant Herbicide can be tank mixed with Roundup® brand agricultural herbicides and applied to cotton and soybean products that include Roundup Ready® technology. The encapsulation technology helps provide improved crop safety and up to 30 days of residual weed control.
