The Pest Management Regulatory Agency recently announced results of its re-evaluation of Mancozeb, a broad-spectrum fungicide for agriculture and horticulture crops. Perhaps curiously, the PMRA final decision allows for the continued use of Mancozeb for foliar use on potato crops, the largest acreage use of the fungicide currently. All other uses of Mancozeb are being cancelled… Read More

Update, June 29: The CFIA has published its incident report on the discovery of unapproved GM wheat plants in southern Alberta. The agency says it determined it was an isolated case, with no wheat entering the food or feed system, but that it was unable to determine where it came from: “The CFIA in cooperation with… Read More
Is the clock ticking on the future of your ground sprayer? Could it eventually be replaced by a swarm of UAV sprayers that could better target weeds and deliver herbicide to exact locations in the field? These are questions we explore with AGRIS Co-operative agronomist Dale Cowan on this episode of RealAgriculture’s Corn School. Cowan recently… Read More
It’s not necessarily the happiest of discoveries, but it’s a first-of-its-kind discovery, nonetheless. Work out of the University of Guelph has confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. What’s more, Dr. Peter Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and… Read More
Bayer and Bosch are working together on a three-year research collaboration to develop a precise spraying technology that will minimize herbicide use, while also mitigating against resistance development. The technology, called Smart Spraying, will see camera sensors identifying weeds, and precise herbicide application targeting them on a single pass, within a fraction of a second. According… Read More
Which clubroot-resistant canola variety with herbicide tolerance trait X is the earliest maturing in your area? What about the highest-yielding blackleg resistant variety with herbicide trait Y? Every year the Canola Council of Canada administers the Canola Performance Trials — a third-party small plot and field scale evaluation of current canola varieties. The program is… Read More
Kelvin Heppner and Shaun Haney are back in the host chairs, with our very own Bernard Tobin joining them off the hop. In today’s episode of Agronomy Monday: An update from the Canadian Farm Writers’ Association conference. Kelvin’s Hot Picks – sitting 3 for 4. Spray specialist Tom Wolf joins to talk about the Academic… Read More
Most of the yellow patches in soybean fields in Western Canada and the northern U.S. have disappeared as the plants have recovered, or turned necrotic and died, but one of the big questions heading into harvest is: what toll did widespread issues with iron deficiency chlorosis (IDC) earlier in the season take on yields? The… Read More
Taking a break from peas or lentils for six years is a tall order for fields where aphanomyces has been a problem. Are there in-field options or tools for managing this relatively new disease? Syama Chatterton, pulse crops pathologist with Agriculture and Agri-Food Canada in Lethbridge, has been conducting field trials across the prairies over the last two… Read More
Will bare fields and warm weather cause wheat to break dormancy? And if so, could we be looking at a wheat price rally for 2017? That’s where we start with Wheat Pete’s Word, and from there Peter Johnson takes us on a wild agronomy ride that covers strip-tilling dry beans into hay ground, what to… Read More
As canola seed prices have risen, farmers across the prairies have cut back on the amount of seed they’re putting in the ground. The Canola Council of Canada still recommends aiming for 7 to 10 plants per square foot with uniform emergence and spacing, but many farms have been targeting lower plant stands — in the… Read More
Recent research findings from the new Canadian Centre for Food Integrity could leave farmers scratching their heads. It showed that the public highly regards farmers, which is great. But it also showed 90 per cent say they know little or nothing about farming. Fortunately, 60 per cent said they want to know more. “I think… Read More
Herbicides are one tool for managing cleavers in canola, but there are many other “small hammers” in the toolbox as well. Seeding rates, row spacing, control timing, and crop rotation all need to be considered, explains Ian Epp, agronomy specialist with the Canola Council of Canada, in this episode of Canola School. “We can add a… Read More
The gene gun, the first of which literally used a .22-calibre bullet, was invented by plant geneticists working at Cornell University in the 1980s as a way of injecting DNA into plant cells. The technology made the process of introducing new genetic material to many major crops, including corn and wheat, much more efficient, helping to create plants with resistance… Read More
Glyphosate-resistant kochia has started showing up in more of Western Canada, and as with other cases of resistance, it’s becoming evident you can’t rely on a single tool for too long. Minimizing resistant weed populations requires an integrated or diverse approach. The crop itself must help make survival difficult for potentially resistant weed seedlings, explains Rob… Read More
