FMC’s Intruvix helps tackle resistant weeds with multiple modes of action

A glyphosate add-in can help maximize early-season weed removal and manage resistance.

Sending glyphosate out alone for your spring burnoff is something that might end up costing you dearly down the road.

According to weed scientists, continuously using a herbicide with a single mode of action accelerates herbicide resistance. Hitting the same weeds at the same time using products with the same modes of action creates a constant pressure that can result in a change in weed population or a change in weeds where they adapt and become resistant. Either way, you’re potentially training weeds to win.

Products with multiple modes of action will keep glyphosate effective

“We all know the value that glyphosate brings to the field and we need to ensure it remains efficacious well into the future,” says Rob McClinton, burnoff, cereals and PrecisionPac^® product manager for FMC Canada. “Adding other modes of action to your spring cleanup application will help protect your future glyphosate use.”

New Intruvix™ herbicide from FMC can be an important component in a herbicide resistance management strategy. It’s the first resistance-battling, four-modes-of-action combination when added to glyphosate. With Groups 2, 4, 9 and 14, Intruvix herbicide hits weeds at multiple target sites.

“Intruvix herbicide is going to be a key tool for cereal growers in Western Canada as they combat an increasing number of resistant weeds,” says McClinton.

Intruvix herbicide: Fast-burning activity with the power of systemic action

“Growers who use Intruvix herbicide prior to cereals will see fast-burning activity with the power of systemic action on some tough-to-control weeds,” says McClinton. “The overlapping activity provided by four modes of action working together results in cleaner fields for farmers without the worry of a resistant weed escape.”

There are over 30 weeds on the Intruvix herbicide label including tough-to-control weeds such as herbicide-resistant kochia (including biotypes resistant to Groups 2 and 9), narrow-leaved hawk’s-beard, cleavers, and volunteer canola.

The product also offers wide-open recropping flexibility next spring when applied as a spring burnoff or chemfallow application. When applied post-harvest, re-cropping options include canola, corn, oats, spring barley, soybeans, wheat (spring or durum) and white beans. It’s suitable for all soil types from brown to black to grey.
