Warrant Ultra herbicide premix is an option for next year

Soybean and cotton growers looking for new tools to manage weeds will have a new, first-of-its-kind option in 2016 with Warrant Ultra herbicide, a premix of acetochlor and fomesafen approved by the U.S. Environmental Protection Agency (EPA) last month but awaiting some state approvals; therefore, it isn't being promoted for 2015 use at this late stage of planting.

Warrant herbicide with its active ingredient acetochlor was launched in 2010. Monsanto Company says it became a favorite among soybean and cotton growers for its residual weed control including control of glyphosate-resistant and tough-to-control weeds as well as its crop safety due to its unique microencapsulated formulation. Roundup Ready PLUS Crop Management Solutions recommendations have included products containing the active ingredient fomesafen as a key weed-management option since the launch of the platform in 2011. When fully approved, Warrant Ultra herbicide will be the only premix on the market to formulate microencapsulated acetochlor with fomesafen, and will provide two mechanisms of action (MOA) for residual weed control. Fomesafen provides useful herbicide resistance management tool when used in the Roundup Ready system, Monsanto suggests.

"Warrant Ultra herbicide provides excellent post-emergence control of problematic weeds such as waterhemp and Palmer amaranth as well as excellent broad-spectrum residual weed control in a convenient premix, said Austin Horn, Monsanto's Marketing Manager for Selective Herbicides.  "University research shows that Warrant Ultra herbicide provides excellent residual control of annual grasses and small-seeded broadleaf weeds when compared to competitive products. Because of its microencapsulation technology, Warrant Ultra herbicide also offers superior crop safety when compared to competitive products.

The new premix herbicide received EPA approval on April 14, and state registrations are anticipated for key soybean and cotton geographies in the coming weeks.

Warrant Ultra herbicide will be part of the Roundup Ready PLUS Crop Management Solutions recommendations and incentives in 2016, the details of which will be announced this fall. The solutions program focuses on providing growers with recommendations, education and incentives through the combined knowledge of scientists, academics, agronomists and industry partnerships, according to Monsanto.

The 2016 introduction of Warrant Ultra herbicide follows the 2015 introduction of Rowel herbicide and Rowel FX herbicide, which Monsanto says can provide cotton and soybean growers consistent weed control on tough-to-control broadleaf weeds.
