You may have only got up close and personal to fababeans at a field day (such as Canolapalooza in Lacombe in 2019) but the pulse may soon be more widely grown — especially if aphanomyces limits the ability to grow peas and lentils every three or four years.

What can you grow if root rot kicks out peas and lentils?

You may need an eight-year break between those crops, but there are some other pulses to consider

Glacier FarmMedia – With aphanomyces threatening peas and lentils, what can producers do to keep pulses in the rotation? Pulse growers are being urged to go up to eight years between plantings of either peas or lentils, which dominate pulse acres in the province. “Our susceptible crops are pea and lentil and, to a lesser extent, dry […] Read more

New pathotypes of clubroot able to overcome resistant canola varieties are being found every year — and they will win the war if producers don’t take a multi-pronged approach to limiting their spread, says Keisha Hollman, University of Alberta project lead.

New clubroot pathotypes overcome genetic resistance in canola

Over half of the unique clubroot pathotypes in Prairie fields able to overcome first-generation resistance

Glacier FarmMedia – New clubroot pathotypes are emerging in canola fields across the Prairies and clubroot-resistant varieties might not be enough to stop the spread.  “The most worrisome part about this is the fact that a lot of these new pathotypes are able to overcome traditional first-generation resistance,” said Keisha Hollman, who led the study […] Read more


The openings on the roots of soybean plants infected by SCN may cause the plant to be more susceptible to the development of root rot and seedling diseases.

Crop disease experts take stock of 2020

Your provincial roundup of pulse and soybean diseases, what to watch for this year and emerging threats

From east to west, pulse and soybean growers face disease challenges, and last year was no different. For example, producers from all three provinces struggled with aphanomyces root rot in peas and lentils, Manitoba’s soybean farmers were warned of increased cases of soybean cyst nematode (plants are more susceptible to root rot and seedling disease […] Read more

This post-harvest photo of a canola stem with verticillium stripe shows how the stem has senesced and the epidermis is shredding to reveal the microsclerotia.

Verticillium stripe should be on your radar for 2020 and beyond

Three things you need to know about the disease

When Verticillium longisporum-infected canola was first discovered in Manitoba in 2014, it was quickly followed by countrywide soil surveys conducted by the Canadian Food Inspection Agency in 2015. Those surveys revealed V. longisporum populations in British Columbia and every province eastward as far as, and including, Quebec. And while it hasn’t reached the point where […] Read more


Myths, yarns and ridiculous claims

Myths, yarns and ridiculous claims

Many long-standing popular myths about agriculture have been disclaimed by science

After 60 years of work and observations in Canadian, British and U.S. agriculture, most of it on the Canadian prairies, I still cannot believe how many farmers and scientists believe in plain falsehoods. Here are a few of those unsubstantiated myths. Manure causes lodging FALSE: If you apply 10 to 20 or more tons of […] Read more

Worried about pea disease? Try peaola

Intercropping peas and canola can minimize disease and lower production costs

With international pea processor Roquette opening a plant in Portage la Prairie, Man., in 2020, many growers will be thinking about taking advantage of the opportunity. Some, however, will be worried about one of the biggest challenges of growing peas: disease. There may be a solution, though. Researchers and experimental farmers are finding answers in […] Read more


blackleg in canola

New labels for blackleg resistance

New “groups” for blackleg resistance on some canola seed this spring

Agronomists agree the best way to control blackleg in canola is rotation — only growing canola once every three years, at most. Besides rotations, scouting and fungicide can help in the fight against blackleg. And, last spring a new item was added to the list of blackleg-fighting tools: a new labelling system. This season, you’ll see some new letters on some of your seed […] Read more

Sclerotinia on a canola plant stem.

Four tips to help prevent crop diseases

Growers know which diseases exist in their fields and how to manage them, especially widespread diseases like sclerotinia, blackleg and clubroot in canola. However, changing management practices have altered the prevalence of many diseases, leading to an increase in frequency and affected areas due to over-reliance on genetics rather than good management practices. Growers should […] Read more


Blackleg in canola.

Helping our plants to help themselves

One day, farmers may be able to use natural products to fight blackleg and other diseases

New research that could lead to a biological alternative to chemical fungicides began with work into food safety. “We were interested in whether food-fermenting lactobacilli would produce molecules that prevent fungal growth,” says Dr. Michael Gaenzle, who is leading the research into antifungal lipids at the University of Alberta. Gaenzle’s team came across some molecules […] Read more

Fusarium infected wheat.

Use those fusarium maps

Know your risk: fusarium maps offer another metric for spraying decisions

What if farmers could predict Mother Nature’s moods in the growing season? The idea is becoming less and less far-fetched with advances that help producers put a number on disease risk. But fusarium head blight (FHB) risk assessment maps are only one factor among many influencing spraying decisions. FHB risk assessment maps have been available […] Read more
