Two new types of herbicide-resistant grain sorghum originally developed by Kassim Al-Khatib and Mitch Tuinstra, former faculty in K-State Agronomy, are getting closer to the commercial market. This includes ALS-resistant sorghum and Assure II-resistant sorghum. Both of these new traits are non-GMO.

These new hybrids will provide producers for the first time with a means of postemerge annual grass control in grain sorghum. The new traits were licensed to DuPont, which is developing both the commercial lines of these herbicide-resistant hybrids and the herbicides to be used on these hybrids. Other seed companies are working with DuPont to develop their own hybrids that incorporate these traits.

At a demonstration field day in Manhattan on July 13, DuPont unveiled more details.

The hybrids will go under the name of "Inzen" technologies. The ALS-resistant sorghum will be called "Inzen Z," and the ALS herbicide to be used on these hybrids will be called Zest. The Assure II-resistant sorghum will be called "Inzen A II," and the herbicide to be used on these hybrids will be Assure II.

According to DuPont representatives, the new hybrids and the herbicides developed for use with the new hybrids will be released at the same time. Registration and early acreages of this new technology are scheduled for 2012.

The development of ALS and Assure II-resistance in sorghum was made possible in part by funding from the Kansas Grain Sorghum Commission and the United Sorghum Checkoff Program.
