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

By Alexis Kienlen June 14, 2021

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

By Glen Hallick - MarketsFarm, GFM Network News July 21, 2020

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

By Ralph Pearce August 17, 2018

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

Three more crop diseases to watch for in 2017

By Jennifer Blair June 21, 2017

Our three experts have pinpointed fusarium head blight as the No. 1 disease to watch out for this year — but keep an eye on these ones, too.

Four canola diseases to watch for

By Lisa Guenther April 25, 2017

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

By Jennifer Blair January 23, 2017

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[...]

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

By Alexis Kienlen July 26, 2016

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

By Dave Sims June 28, 2016

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[...]

Root rot pathogen lying in wait

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

By Jennifer Blair February 10, 2016

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[...]

Pea growers weigh demand opportunities against root rot

By Dave Sims April 6, 2015

CNS Canada — Pea acreage in Western Canada could rise by five to 10 per cent this year, according to one industry expert, who notes root rot threatens to curtail that projection. Demand from India, China and Bangladesh is strong and that means total pea area could hit four million acres, said Carl Potts, executive[...]
