The product includes a built-in safener for tank mixing with glyphosate
BASF is bringing a new weed control product to Canadian corn farmers for the 2027 season.
Calovor combines dicamba (Group 4) and diflufenzopyr (Group 19) for post-emerge control of weeds like kochia, wild buckwheat, Canada thistle, and redroot pigweed.
“The Group 19 acts as a transport agent, so it brings the dicamba to the growing weed’s growing points,” Rob Miller, regional technical service manager with BASF, told Farms.com. “So that’s where we actually get more consistent control of a larger broadleaf weed.”
Heavy densities of wild buckwheat can result in a 10-15 per cent yield loss in corn, AAFC research shows.
The herbicide has a 4-hour rainfastness, and a wide application window from the 2- to 8-leaf stage, to help producers manage weeds early or later throughout the season.
In addition, the herbicide has a built-in safener to provide farmers with more flexibility.
Isoxadifen lets farmers tank mix Calovor with other products.
“The benefit of the safener is you can tank mix it with glyphosate,” Miller said.
Farmers can also tank mix Calovor with Armezon, Liberty 20 SN, Zidua SC, and other herbicides.
BASF results from 2026 plots in Winkler, Man., show the Calovor and Armezon combination provided 92 per cent efficacy on kochia, 88 per cent efficacy on redroot pigweed, and 93 per cent efficacy on lamb’s quarters.
Farmers interested in learning more about Calovor can contact a local BASF rep.
The product will be on display during grower and retail meetings in Eastern and Western Canada, Miller said.
