Gramoxone SL herbicide registered

Syngenta in North America announces the U.S. registration of Gramoxone SL herbicide, a new formulation of Gramoxone with increased mixing compatibility and improved handling characteristics. 

“Syngenta continually looks for formulations that will improve the user experience,” said Kevin Gesse, Syngenta asset lead. “We are pleased to offer this proven chemistry in a new formulation for the upcoming season.”

A Syngenta Resistance Fighter brand, Gramoxone SL offers the same proven, highly effective control of a broad spectrum of weeds and grass as Gramoxone Inteonherbicide, including those with resistance to other herbicides.

The new formulation contains the same concentration of paraquat as Gramoxone Inteon, but without the Inteon (alginate) technology.  Gramoxone SL mixes readily with various qualities of water and calcium-containing nitrogen fertilizers, including CAN17. 

Label rates and uses for Gramoxone SL are the same as Gramoxone Inteon. Gramoxone SL will replace Gramoxone Inteon, which will no longer be produced.
