New herbicide tolerant soybean traits in the pipeline
New herbicide tolerant soybean trait technology is on schedule for commercial introduction. Dow AgroSciences’ new herbicide tolerant soybean event, the second product incorporating a new family of herbicide tolerance traits has been submitted to the US Department of Agriculture (USDA).


The trait package for soybeans conveys tolerance to the broadleaf phenoxy ausin herbicide 2,4-D and is expected to provide control of glyphosate-resistant weeds, says the company. Dow plans to stack this trait with other traits offering tolerance to glyphosate.

According to Dow AgroSciences, the new herbicide tolerant trait technology provides farmers with greater flexibility in 2,4-D use, allowing planting immediately after application as compared to the delays required under current labeling. •

New one-pass herbicide solution for corn
The first one-pass, post-emergence herbicide for glyphosate-tolerant corn is now registered in Canada. Halex GT from Syngenta Crop Protection Canada provides residual control and contains multiple modes of action. 

The formulation incorporates three Syngenta products: Callisto, which provides control of emerged weeds as well as residual broadleaf weed control, Dual II Magnum, which provides season-long control of broadleaf weeds and grasses, and Touchdown Total, which controls emerged weeds.

Data shows this combination of active ingredients provides control of emerged weeds and residual activity on broadleaf weeds and grasses in glyphosate-tolerant corn, including nightshade, velvetleaf, lambsquarters, pigweed and foxtail, says the company.

“We recommend that growers take the Foundation Acre™ approach and apply an early-season application of Primextra II Magnum® – a practice that has been proven to develop stronger root systems and better plant stands, and ultimately higher yields. However, we recognize that the timing required for this practice makes it challenging for some growers,” says Wayne Bennett, Brand Manager with Syngenta Canada. “In these select cases, Halex GT is an excellent alternative. The Halex GT formulation gives growers strong residual control and application timing flexibility. Growers will not have to wait for later-emerging weeds to appear, and their fields will be kept clean from application to crop canopy with only one early post-emergence application.”
