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

Reading Time: 5 minutes 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 bean.

Pulse weekly outlook: Saskatchewan pulses heading for a good year

MarketsFarm — Pulse crops in Saskatchewan are in shape to have a good year, according to Dale Risula, a pulse specialist with the province’s agriculture department. “Pulses got off to a pretty good start. Moisture levels in the soil were pretty good. Most of the pulses were up and growing rapidly,” Risula said, noting pulse […] Read more

Pearce: Multiple modes of action an emerging reality for fungicides

As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more



Four canola diseases to watch for

Four canola diseases to watch for

Is that canola crop afflicted by blackleg, root rot, both, or something else entirely? It’s a messy question farmers and agronomists encounter every year. Presenters tried to untangle those problems at CanoLAB in Vermilion this winter. Here are four diseases to watch for in canola fields this summer, and tips on diagnosing them.

When combined, fusarium and aphanomyces root rots increase the likelihood and severity of disease in pea fields, said plant pathologist Syama Chatterton.

Root rot pathogens deliver one-two punch to pea fields

Reading Time: 3 minutes Two root rot pathogens are teaming up to wreak havoc in Alberta’s pea fields. “Before 2016, I thought that we were just dealing with fusarium root rot in the brown soil zone, but 2016 completely changed that hypothesis,” said Syama Chatterton, plant pathologist with Agriculture and Agri-Food Canada. “We saw a lot of aphanomyces root[...]

A pea field affected by root rot often looks yellow and withered, but some infected fields don’t look as bad as others.

Root rot rears its ugly head — and there’s no treatment

Peas are the biggest concern and even when fields look OK, root rot can still be there

Reading Time: 3 minutes Pulse acres have increased in Alberta this year, but unfortunately root rot has increased as well. “We’re hearing and seeing evidence of pretty extreme root rot in pulses, especially peas,” said Mike Harding, research scientist and plant pathologist with Alberta Agriculture and Forestry. “It doesn’t look like it’s going to be a great year for[...]

Rain increases disease pressures on eastern Prairies

CNS Canada — The recent batch of wet weather across parts of Saskatchewan and Manitoba have been a welcome relief to some fields that were suffering from excess dryness. However, soggy conditions have also enabled certain disease pressures to rear their ugly head, according to some government specialists. “Root rot is showing up in peas[...]

This pea field near Three Hills was devastated by root rot in 2014, 
but pea growers saw fewer disease problems in 2015.

Root rot pathogen lying in wait

Aphanomyces can persist for a decade in soil and are just waiting for another wet year

Reading Time: 3 minutes Syama Chatterton had a hunch that pea root rots would be less of a problem in a dry year. And sometimes, she said, “it’s nice to be right.” “Root rot severity was definitely lower in 2015 compared to what we had seen in 2013 and 2014, which were very wet years,” the federal research scientist[...]
