Fifty-nine weed species around the world have developed some resistance to glyphosate, according to data from the International Survey of Herbicide Resistant Weeds. Countries and regions including Mexico and the European Union have come close to banning its use, based on perceptions or misperceptions of its safety and the risk to human health.

Considering these factors, Canadian farmers may need alternatives to glyphosate in the future…. Shane Collins, [a master’s student from the University of Alberta, and other researchers have been] evaluating herbicides that could replace it for application in late summer and early fall.

“At some point, farmers are going to need more options for herbicides that (they) can apply on wheat,” said Collins, who is part of a group testing herbicides in plots at sites throughout the Prairie provinces.

The project is in the early stages, but he has identified four herbicides that could possibly be used in tank mixes to replace the popular herbicide. One large challenge will be the price per acre because glyphosate is relatively inexpensive.
