New methods of mechanical weed control show promise, but don’t expect a yield increase the first year

By
With the high and growing percentage of Prairie cropland infested with herbicide-resistant weeds, researchers are turning their attention back to mechanical control, but that doesn’t necessarily mean tillage. The Alberta Wheat Commission and Saskatchewan Pulse Growers are partnering on a three-year research project at the University of Saskatchewan which is evaluating in-crop weed clipping as […] Read more

Agrimetrix takes aim at exploding sprayer myths

Farmers today need to spray several times a year, and two former AAFC researchers have formed a company to help them get the product to the right place at the right time

By
If Tom Wolf is the face of agricultural spraying in Western Canada, then Brian Caldwell is the hands. The two co-owners of Agrimetrix, an agricultural spray research and training company based in Saskatoon, share an overlapping skillset, but they have carved distinctive individual niches. Wolf spends much of his time talking about spraying in a […] Read more
