Nufarm launches herbicide technology to help farmers combat weeds in cereals

November 14, 2023  By Top Crop Manager

Nufarm Canada has launched its proprietary Duplosan™-powered suite of cereal herbicides. This first-in-market, novel pipeline of solutions will help farmers combat challenging weeds in cereals including resistant kochia.

The result of research and innovation led by Nufarm and its field work in Western Canada, the team has unlocked new potential with Duplosan, the foundation of Nufarm’s quest to find the “Path of Least Resistance” for growers. The technology is showing positive results as a different chemistry that hasn’t been exposed to most weed populations in Western Canada, specifically kochia.

The first in the new suite of products – Oxbow™ – is a complete and easy solution in the fight against managing hard-to-kill broadleaf weeds including kochia in cereals. Powered by Duplosan technology, it’s an effective way to solve today’s biggest weed control challenges, backed by flexible re-cropping and application timing. Oxbow will be available in Western Canada for the 2024 growing season through preferred Nufarm agriculture retailers.


“As resistant weeds like kochia have accelerated in recent years, expanding to new soil zones, the current herbicide toolbox is just not keeping pace,” says Boyd Bergstrom, Nufarm Canada country lead. In their quest to find new solutions, Nufarm researchers rediscovered dichlorprop-p — an active first used decades ago as an additive to 2,4-D when dichlorprop’s properties largely remained unexplored and its full potential was never unlocked.

“Nufarm will be pairing Duplosan with other modes of action to maximize weed control in cereals,” Bergstrom explains. “Adding the technology will power a pipeline of new herbicides capable of fighting weeds in cereal crops. The proprietary technology is showing extremely positive results as a novel Group 4 chemistry that’s had little exposure to most western Canadian weed populations, specifically kochia.”
