Multiple herbicide-tolerant grain sorghum traits are coming soon to growers across the country, according to Alta Seeds.
Breeder Ben Beyer discussed the types of herbicide-tolerant genetics being brought to market and how soon they will become available for planting.
"We've developed three hybrids with proven resistance to ALS herbicides," Beyer said. "These hybrids have been tested the last two years in field trials using twice the recommended herbicide application rate and they have demonstrated excellent performance with no yield drag."
Working under a joint agreement with DuPont Crop Protection, Alta Seeds herbicide-resistant hybrids will feature the Inzen herbicide-tolerance trait. Inzen was developed through traditional breeding techniques. The trait is non-transgenic and will not have any export restrictions. Beyer said that the release of hybrids with the Inzen trait is pending EPA registration which is expected by 2017.
Beyer announced Alta Seeds has multiple traits for herbicide tolerance in its research and development pipeline, including genetics resistant to imidazolinone, often referred to as "IMI" herbicides.
"Post-emergent weed control is a major research priority for Alta Seeds, and we've identified several proprietary traits that we are aggressively pursuing," Beyer says. "We're focused on delivering solutions to farmers' needs and herbicide tolerance is at or near the top for most sorghum growers."
Grassy weeds such as foxtail, barnyardgrass, crabgrass and Texas panicum are estimated to annually reduce U.S. sorghum yields by approximately 20 percent or an average of 13 bushels per acre. The introduction of herbicide-tolerant sorghum will enhance grower yields and profitability while also providing rotational flexibility, Beyer noted.
