Root rot continues to be a concern for pulse growers and although work is being done on creating varieties that are more resistant to diseases such as aphanomyces, that reality is likely at least eight years away. In the interim, growers are encouraged to employ a comprehensive rotation schedule to best combat root rot in… Read More

NexusBioAg, a division of Univar Solutions, and MustGrow Biologics Corp. have reached an exclusive marketing and distribution agreement in the Canadian canola and pulse market for TerraMG, a mustard-derived soil biopesticide. Designed to combat clubroot and aphanomyces of canola and pea, respectively, the product is not yet registered with Canada’s Pest Management Regulatory Agency. “Growers… Read More
Decisions, decisions. There are many early season considerations that will factor into where to put your next crop of peas, lentils, chickpeas, or faba beans. Seed quality, environmental conditions, whether or not to treat seed, and pest concerns are just some that make the list. One of the great things about pulse crops is that… Read More
Planning concerns for next year’s pulse crops stem mostly from disease concerns, especially aphanomyces. 2020 was a really wet year, and there were pockets that saw a lot of moisture, which resulted in increased roots rots and that nasty soil-borne disease — such as aphanomyces — which makes planning for the future crucial. “We saw… Read More
A few of our pea fields looked a bit pale in comparison to the others earlier this season. The crop colour was off, and not just in low lying spots, as one might expect with all the moisture west central Saskatchewan has received. On further investigation, ruling out other reasons like fertility and plant stand,… Read More
If dogs can detect trace amounts of drugs in luggage, could they be trained to sniff out plant disease, too? The short answer is yes — and a research scientist headed up a project to prove it in a one-year, proof of concept study out of Alberta. Mike Harding, research scientist with Alberta Agriculture &… Read More
There are a lot of concerns in the pulse market at the moment. Things such as competition from the Black Sea region, and what’s happening with the election in India, can keep farmers up at night. While you have one eye on the markets, it’s also important to keep the other on agronomy. This is… Read More
Should I or shouldn’t I plant soybeans this spring? This is a question on the minds of many farmers as we head into spring of 2019. For a few years, it looked like soybeans were going to take over many acres across the southern Prairies, but a couple of bad years for soybeans have caused… Read More
Each fall the Western Forum on Pest Management meets to review the previous growing season. Scientists, researchers, and agronomists get together to compare notes on what happened during the previous growing season. This helps everyone get a better understanding of the issues so that they can help each other help farmers. Dale Leftwich, field editor… Read More
For parts of Western Canada, the rain keeps on pouring. Early wet conditions could be conducive to root rot problems in pulses. Fortunately, for three of the four main culprits —rhyzoctonia, fusarium and pythium, the plants will generally grow through the vulnerable early seedling stage if a seed treatment has been applied, notes Robyne Bowness-Davidson, pulse… Read More
Aphanomyces is a soil-borne water mold thatcauses devastating root rots in pulses, especially pea and lentil crops. Unfortunately for farmers, the aphanomyces spores can live in the soil for 10 years, and thrive under wet conditions. That means, not only has this root rot advanced rapidly across many areas of Saskatchewan and Alberta, but it’s… 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
Tough to say and even harder to control, aphanomyces has the potential to significantly reduce pea and lentil yields, and can stick around in the soil for an extremely long time. It’s recommended that farmers not plant pea or lentil for five to six years if aphanomyces has been confirmed in a field, but that’s… Read More
With wet growing conditions in many areas and high prices driving tight pulse crop rotations, the table was set for root rot to feast on pea stands in Western Canada this year. While one of the main culprits — aphanomyces — was first confirmed in Saskatchewan in 2012 and in Alberta in 2013, testing on the pathogen… Read More
Round one of fungicide application is done, but it’s starting to wear off and conditions are still conducive for disease. Knowing what your peas and/or lentils are worth this year, do you take the sprayer out or hire a plane for a second fungicide application? It’s a scenario growers in parts of Western Canada are finding… Read More
