Winter canola is becoming a more popular crop in southern Ontario.

Winter canola requires herbicide vigilance

Limited varieties are sensitive to herbicide carryover

Producers interested in growing winter canola should consider the herbicide history of their field, and the herbicide options open to them following winter wheat harvest. There are a number of restrictions, and some herbicide labels do not mention safety on canola. Only one winter canola variety is registered in Ontario and available to producers. It […] Read more

Smart sprayer shoots weeds with a targeted herbicide blast

The technology will mean driving slower, but using much less product

Glacier FarmMedia – A Smart Sprayer, equipped with boom-mount cameras coupled to Xarvio image recognition technology, can identify 20 species of weeds and trigger a surgically precise herbicide blast to one specific weed. Why it matters: Conventional field spraying coverage dumps millions of litres of unneeded herbicide on millions of Canadian acres, which represents a […] Read more

A double-barreled approach to fleabane control

Combined herbicide-cover crop approach can provide effective control

As herbicide-resistant Canada fleabane and other problem weeds continue to frustrate farmers, more creative control solutions are being sought. Planting cover crops, specifically cereal rye is a good tactic, say researchers from the University of Guelph and the Ontario Ministry of Agriculture, Food, and Rural Affairs. Why it matters: Herbicide-resistant weeds are creating more challenges […] Read more

Solving spray problems with new technology

Sprayer innovations can help reduce herbicide resistance by making sure lethal doses are delivered to weeds

How farmers spray their crops — not just what they spray — could be contributing to growing weed resistance across Canada. Technology is emerging, though, that can help overcome common spraying challenges. That’s according to Tom Wolf, President of Agrimetrix Research and Training, a Saskatoon-based company that specializes in spray application. Why it matters: Smart […] Read more
