New technology promises grass control in grain sorghum

LSU AgCenter researchers say new Inzen technology could have a place in controlling Johnsongrass in grain sorghum.

Mid-South growers have encountered a number of problems with grain sorghum, not the least of which is controlling Johnsongrass in the crop. Sugarcane aphids is another problem and price another.

A new non-GMO technology that confers ALS tolerance in grain sorghum is showing promise for helping producers solve the problem of controlling Johnsongrass and annual grasses during the crop season.

The product, called Inzen, is the result of a natural selection process in which Kansas State University researchers found shattercane that was tolerant to nicosulfuron, the herbicide in Accent and Beacon, and transferred the tolerance to grain sorghum.

Dr. Daniel Stephenson, weed scientist at the LSU AgCenter’s Dean Lee Research and Extension Center in Alexandria, La., talked about Inzen in a presentation at the Louisiana Agricultural Consultants Association’s annual meeting. The Louisiana Agricultural Technology and Management Conference was held in Marksville, La., earlier this year.
