Monsanto's 'Warrant' Herbicide Receives Expanded Pre-Emergence LabelMon, 06 Aug 2012 12:09:00 CDT
Cotton and soybean farmers have a new pre-emerge tool for residual weed control. Warrant® Herbicide 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.”
Dr. Stanley Culpepper, Professor and Extension Agronomist at the University of Georgia, has conducted pre-emergence trials with Warrant Herbicide. “If you’re a cotton producer, you’re well aware of a herbicide called Warrant Herbicide – you’re using it post-emergence,” Culpepper says. “But when we come to talk with you this winter, we’ll tell you to use it pre-emergence. In fact, I think it’s the safest pre-emergence material we can use.
“We won’t use Warrant Herbicide by itself. We’ll still need to tank-mix it with another chemistry to help protect it. But it will reduce our input costs a little bit, and it also will reduce our herbicide injury slightly,” he says.
