By Angela Lovell May 20, 2016

It’s never a good idea to overreact when you see insects on your crops because jumping the gun, and spraying if it’s not really necessary, can do more harm than good. “Seldom, if ever, do preventative insecticides actually pay us,” says Scott Meers, insect specialist with Alberta Agriculture and Forestry. “When we spray just to […] Read more

Herbicide resistant weeds aren’t a novelty anymore — now they’re just the norm

By Lisa Guenther April 6, 2016

While herbicide resistance isn’t a new problem, it is a growing one. Today 80 countries report herbicide-resistant weeds, says a researcher. And Canada is near the top of that list.

Paris | Reuters — French lawmakers approved plans for a total ban on some widely used pesticides blamed for harming bees, going beyond European Union restrictions in a fierce debate that has pitched farmers and chemical firms against beekeepers and green groups.

Early season weed control is key

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

By Melanie Epp March 16, 2016

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 Scott Garvey March 9, 2016

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 Lisa Guenther January 19, 2016

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

By Lisa Guenther January 5, 2016
