Managing diseases in alfalfa
From seedling issues to stand die-off, understanding the timing and symptoms of alfalfa diseases can help protect yield
Saskatchewan researchers find some pea varieties naturally resistant to root rot
Further testing is underway to more clearly distinguish the contenders
Tests of field pea varieties this past summer in plot trials suggest some commercial varieties have more genetic resistance to root rot than others — not a huge amount of additional resistance, but in some cases marginally better.
Aphanomyces still a stubborn foe
Research offers hope, but proper crop management remains the best defence for today
In today’s bad news/good news ledger of pulse crop diseases, the bad news is there’s still no quick fix for controlling root rot in field peas and lentils. On the good news side, there are management options that help reduce the risk, research is narrowing in on some treatments that may help control the disease, […] Read more
No easy fix for pulse crop problems
A Saskatchewan pulse producer weighs his options and risks for planting lentils in fields previously hit hard by aphanomyces — plus, the latest research and recommendations on root rot management in pulses
Shaun Dyrland says even in a dry growing season, if there is a thunderstorm that drops about an inch of rain some of the lentil fields on his west-central Saskatchewan farm will be dead within a matter of days. That’s just an indication of the effect root rot disease — particularly aphanomyces — can have […] Read more
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
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
How to identify and prevent root rots in canola
If you’re not scouting for root rots, that doesn’t mean they’re not there
Survey data from Western Canada’s provincial agriculture departments don’t have really good numbers when it comes to root rots. The difficulty is not many growers are scouting for them, but that doesn’t mean they aren’t there. The pathogens that cause root rot can impact yield severely, especially if infection occurs early in the season. The […] Read more
Yes to peas, no to aphanomyces
Peas are a great crop for the Prairies, but aphanomyces root rot is a major threat
Peas as a human and animal feed have been around since 5000 BC. The pea plant, a nitrogen-fixing legume, originated in the cooler areas of the Himalayas and was subsequently cultivated extensively in the Mediterranean basin. Peas, dried peas in particular, were a major part of the diet in the U.K. in the 19th and […] Read more
Preventing and controlling aphanomyces root rot
Aphanomyces root rot is not airborne or seedborne, like clubroot of canola, the disease is soil borne. This fungus, like clubroot, forms resting spores that can last for 10 years in infested soil. Infection of the legume host can take place at anytime in the season but is not obvious early in the year. The […] 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
