DuPont, K-State Partner on Herbicide-Tolerant Sorghum Hybrids

ALS-, ACCase- traits will be advanced by DuPont plant breeders.

DuPont and Kansas State University Research Foundation have signed an agreement giving DuPont exclusive commercialization rights to two new herbicide-tolerant traits in sorghum.

The new traits, developed by Kansas State University researchers, include an ALS-herbicide- tolerant trait and an ACCase-herbicide tolerant trait. Both traits will provide growers with new, more flexible postemergence herbicide options for grass control in sorghum with no restrictions on export marketing.
Growers will benefit from new herbicide solutions developed with the unique blends technology from DuPont Crop Protection for use on sorghum with the new ALS-tolerant trait. Seed companies will have the opportunity to sub-license the both traits from DuPont.

"Our partnership with Kansas State will allow us to deliver solutions for grass and broadleaf weed control in sorghum that have never before been available," said James C. Collins, vice president and general manager - DuPont Crop Protection.

"One of the greatest challenges sorghum growers have faced over the years is control of weeds in the crop," said Forrest Chumley, Kansas State research and extension associate director for research. "To solve the problem, we needed to work with a company, such as DuPont, that has optimal herbicide chemistry, access to good crop genetics, and the willingness to make the innovation available broadly. This is a huge step for sorghum production."

Growers currently rely on preemergence grass herbicides that require rainfall for activation. These treatments can be inconsistent, especially in the High Plains where annual rainfall frequently is limited. The new ALS-tolerant and ACCase-tolerant traits will provide sorghum growers with postemergence grass and broadleaf weed control options needed for more versatile application timing. The new traits, developed using conventional methods, will also allow growers greater rotational flexibility to sorghum from other crops.

The traits were developed by Kansas State agronomy researchers including Kassim Al-Khatib and his former colleague Mitch Tuinstra (currently at Purdue University).

Chumley said the effort was made possible by strong support from the Kansas Grain Sorghum Commission and National Grain Sorghum Producers.

The United States is the world's largest producer of grain sorghum at about 300 million bushels per year. Kansas has long been the leading state in grain sorghum production, accounting for nearly half of the annual U.S. crop.

The mission of the Kansas State University Research Foundation is to promote, encourage and aid scientific investigation, research and technology transfer at Kansas State University to return the greatest advantage to the creators, K-State and the general public. In 2006, grain sorghum sales pumped $487 million into the Kansas economy. The Kansas Agricultural Statistics Service indicated that Kansas growers produced about 212 million bushels of grain sorghum in 2007.
