BASF Canada recommends that growers take proactive steps to help control glyphosate resistance after a recent study found kochia plants from two sites in Manitoba to be glyphosate-resistant. The study tested plants from 283 sites across the province.
The confirmation of glyphosate-resistant kochia in Manitoba makes it the province’s first. The number of sites where glyphosate-resistant kochia has been confirmed has grown from the original three sites in Southern Alberta to include sites across Saskatchewan.
“Glyphosate is an important herbicide that we need to protect for the future,” said Danielle Eastman, Western Herbicide Brand Manager for BASF Canada. “Using proper management techniques will be critical to prolong the use of this valuable tool.”
The two sites that tested positive for glyphosate resistance represent less than one percent of the total number of sites tested. Manitoba growers have an opportunity to delay the spread of the weed by using proper management techniques.
“BASF is committed to working with growers in Manitoba and across the country to help delay the spread of resistance,” said Eastman. “Tank-mixing products with unique modes of action like Heat® and Distinct® to your glyphosate is an important management practice that all growers should be using.”
Tank-mixing and using multiple modes of action are even more critical since most of the kochia in Western Canada is resistant to Group 2 herbicides. Heat provides control of broadleaf weeds with a unique Group 14 and Distinct uses Group 4 and Group 19 chemistries to provide control of annual broadleaf and winter annual weeds.
Researchers will continue to monitor the sites where plants tested positive to try to control the spread but BASF recommends that growers incorporate multiple management practices on their farms and be proactive about managing resistance.
