If history is a guide, a higher number of herbicide resistant weeds will be discovered this year in Alberta when Agriculture Canada researchers survey the province.
Sixty percent of cropland in Western Canada has a weed resistance problem to some degree compared to 15 to 20 percent 10 to 15 years ago.
Research scientist Bob Blackshaw told those at a recent Farming Smarter field event that good weed control is an important part of avoiding herbicide resistance.
“We do want good weed control because resistance is a bit of a numbers game,” he said. “So if you have a lot of weeds in your field, you have a greater chance of that resistant gene being present.”
