Syngenta Axial herbicide contains new built-in adjuvant

Nov. 22, 2012, Guelph, ON - Syngenta Canada Inc.'s Axial herbicide is now available in a new formulation with a built-in adjuvant for control of wild oats, green foxtail, yellow foxtail, barnyard grass, volunteer oats, volunteer canary seed and proso millet in spring wheat and barley.

According to Jon Habok, asset lead, cereal herbicides for Syngenta Canada, the all-in-one Axial formulation makes it more convenient and easier to apply.

"Growers will no longer need to mix products to get the effective grass weed control they are looking for in spring wheat and barley," he says.

Axial herbicide, with its active ingredient pinoxaden (Group 1), is absorbed by plant leaves and is rapidly translocated to the growing points of leaves and stems, providing thorough coverage of the weeds, which is essential for consistent control.

"The Syngenta adjuvant science team has found that this new adjuvant has a unique action on pinoxaden, and increases its uptake versus standard crop oil concentrate (COC) or methylated seed oil (MSO) type adjuvants," notes Dr. Ravi Ramachandran, manager, product chemistry and chemical services for Syngenta Canada. "This is a significant step-change in adjuvant science and technology resulting in enhanced speed of activity for faster and more efficient grass control."

It should be noted that not all Group 1 graminicides, or ACCase inhibitors, are the same. Each product in this category belongs to one of three chemical families. Each family inhibits the same enzyme and has the same site of action, however, each family binds differently to the plant. This distinction means that development of resistance may also differ by family.

The three families of Group 1 active ingredients are: 'Fop' (Aryloxyphenoxy propionate), 'Dim' (Cyclohexanediones) and 'Den' (Phenylpyrazolin). Axial herbicide is a'Den' chemistry and research has demonstrated that it works on some wild oat populations that are not controlled by other Group 1 graminicides.
