New Herbicide Tech on Display

Dow unveils herbicide resistance technology that offers potential for enhanced broadleaf 2012.

In the heat of a mid-day summer sun at the Farm Progress Show, Dow AgroSciences folks talked about their new herbicide tolerance trait for corn. While it hasn't earned a "marketing name" yet, the Dow AgroSciences Herbicide Tolerance trait - or DHT - confers tolerance of certain broadleaf and grass herbicides, including phenoxy auxins like 2,4-D and aryloxyphenoxypropionate - or "fop" grass herbicides, according to Tom Wiltrout, global business leader - corn, DAS.

During a news conference at the show, Wiltrout explained that DHT could be teamed with the company's Herculex insect protection technology to create a corn hybrids that offer a broad spectrum of insect protection teamed with a new level of herbicide tolerance. Herculex already has the Liberty Link technology built in.

Wiltrout notes that farmers are familiar with 2,4-D as an effective, and affordable, herbicide for control of broadleaf weeds. And although it's been on the market for 50 years, it has few resistant weeds. However, the herbicide is not always gentle to corn when used over-the-top. The new herbicide tolerance trait would eliminate that concern.

DAS has also worked to insert the technology into soybeans and cotton, which would come to market later.

Don't go asking for DHT just yet, however, the company anticipates it will start marketing the trait in elite hybrids as early as 2012. This five-year advance look gives farmers a heads up when looking at field trials next year, where the technology will be tested.
