Disease such as seedling blight, and root rots caused by pythium, fusarium or rhizoctonia could affect seedlings, particularly in […] Read more

Early season weed control is key

Spring spraying can be challenging. Look for the right weather and moisture conditions

By
Early season weed control is a top priority for canola growers. Weeds that emerge before the crop are much more competitive than those coming up with the crop, and herbicide can’t undo the damage done by weeds left uncontrolled before emergence. Clark Brenzil, provincial weed specialist with the Saskatchewan Ministry of Agriculture, says research shows […] Read more

PHOTOS: Small-scale sprayers offer targeted weed killing

By
Today’s high-clearance farm sprayers come equipped with boom widths of 100 feet or more, which makes getting them into sharp corners or tight places pretty difficult. And with some precision ag data collection systems now able to pinpoint small problem weed areas in a field, spraying them with very wide booms may mean wasting product. […] Read more

Managing Group-2 resistant weeds in pulse crops across Western Canada

Cleavers, mustard, kochia and sow thistle are among the weeds getting harder 
to control, but there are methods, starting with good agronomy

By
Group 2 resistance is something that is really a big problem across Western Canada,” says Dr. Chris Willenborg, a researcher at the University of Saskatchewan’s plant sciences department. Willenborg has worked on several research projects that inform weed resistance in pulses. The bad news is that resistance is spreading. And the more farmers rely solely […] Read more

What’s it take to produce new pesticides?

Farmers know a lot about using pesticides. Here’s a chance to learn about how chemical companies dream them up, produce them and market them to you
