Formulation saves step for Harmony SG users

Revised, March 3 –– DuPont Canada has rolled out a new formulation of its Harmony SG herbicide combo that allows users to skip the step of adding its adjuvant separately.

Harmony SG has been sold as a combination of DuPont’s Group 2 granular herbicide Refine SG and, until last fall, Syngenta Crop Protection’s Group 1 clodinafop product Horizon 240EC.

The new formulation of Harmony SG instead includes an exclusive formulation of the Group 1 clodinafop. Unlike the 240EC formulation, the new formulation, called Harmony Grass, is pre-mixed with Score adjuvant, saving farmers the step of adding Score to their tank mix. 

“Spring wheat and durum growers in Western Canada will get all the great performance they’ve come to expect from Harmony SG with the added convenience of a built-in adjuvant,” said Jon Gough, DuPont’s product manager for cereals, in a release Monday. “With fewer jugs to handle and rinse, one-pass weed control just got simpler.”

Harmony SG is registered for control of wild oats, green foxtail and five-leaf wild buckwheat, along with other broadleaf weeds. Its window of application is open from two-leaf to the emergence of the flag leaf, DuPont said, and has one-hour rainfastness, no soil residue, no recropping restrictions the following year.

The new version of Harmony SG will be marketed in a “more compact” 40-acre case compared to the previous formulation, DuPont said, adding that it expected to have “limited quantities” of Harmony Mega available for sale by the 160-acre tote.

Both those package sizes will qualify for all current DuPont Harmony programs, and for rebates through Syngenta Partner Program, DuPont said.

CORRECTION, March 3: Harmony SG includes Harmony Grass as its Group 1 component, not Horizon NG as reported in an earlier version of this article. We regret the error.
