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

By
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

AAFC projects focus on aphanomyces root rot in pulse crops

Good management practices still the best way to control aphanomyces in the field

By
While improving management practices and reducing risk factors are still the best ways to avoid root rot in pulse crops, Agriculture and Agri-Food Canada (AAFC) researchers hope to find other tools. Syama Chatterton, an AAFC research scientist whose areas of expertise include diseases in pulse crops and soil borne diseases, is working on research projects that focus […] Read more

Ed Seidle learns on the job

This on-farm research program generated info about everything from aphanomyces to root rot

By
How can producers make sure their on-farm trials produce useful results? Or perhaps a better question is whether growers can, or need to, run trials as rigorously as researchers? Most farmers don’t have the time or patience to run the types of on-farm experiments that scientists do, says Ed Seidle. But that doesn’t mean they […] Read more

Winning the war on pea problems

Weeds, disease and pests will all steal yield from less-competitive pea crops

By
Disease and pests pose a big risk for growers. A little planning can go a long way to limiting the damage. Peas are somewhat less competitive than some other crops like barley, canola or wheat because their canopy is open a bit longer, so weeds get a better start,” said Dr. Neil Harker, research scientist, […] Read more
