The Environmental Protection Agency has issued a Section 3 registration for the use of Flexstar GT herbicide in glyphosate-tolerant soybeans, according to Syngenta Crop Protection.

A pre-mix of fomesafen and glyphosate, Flexstar GT is a resistance management solution for postemergence use that helps sustain glyphosate-tolerant soybean technology. Unlike glyphosate tank-mix options, Flexstar GT contains Isolink II Technology, a unique adjuvant system designed to optimize both the contact activity of fomesafen and the systemic activity of glyphosate while reducing crop injury.

“Weed resistance in the United States is a real and growing problem,” said Rex Wichert, herbicide brand manager with Syngenta Crop Protection, Inc. “With waterhemp and pigweed species already resistant to glyphosate, sustaining the viability of GT technology becomes critical and prevention is vital to that effort. As a Resistance Fighter brand, Flexstar GT offers two modes of action for better postemergence control of troublesome weeds, including glyphosate and ALS-resistant biotypes, helping to delay the development of resistance and maximize a grower's investment.”

Flexstar GT not only controls the same annual weeds as glyphosate, but also several glyphosate- and ALS-resistant broadleaf weeds such as Palmer amaranth, waterhemp and ragweed plus those weeds difficult to control with glyphosate alone such as morningglory and velvetleaf.

Flexstar GT also offers pre-emergence activity on more than 25 broadleaf weeds including Palmer amaranth, pigweed, ragweed and yellow nutsedge.
