Researching root rot control in peas

Evaluating the benefits of seed treatments, soil amendments and soil tests

There’s still a lot to learn when it comes to managing root rot, especially aphanomyces. When are seed treatments most effective? Do soil amendments help? And can soil testing help farmers pick the best pea fields? Fortunately, research is underway to answer those very questions. Dr. Syama Chatterton, an Agriculture and Agri-Food Canada (AAFC) researcher […] Read more

Manage root rot before seeding

Saskatchewan plant disease specialist recommends good agronomy to reduce root rot

Lentil and pea growers struggling with root rot need to manage the disease before the seed is in the ground, according to Saskatchewan Agriculture’s plant disease specialist. Fusarium, pythium, and rhizoctonia are root rot pathogens long familiar to farmers.

Not only will fields that have experienced flooding or high levels of water saturation show symptoms that look like root rot, but Aphanomyces root rot also exhibits similar symptoms as Fusarium spp.

Minimizing the impact of Aphanomyces

There are no in-crop solutions to root rot in peas and lentils. But there 
are ways to minimize your risk of losing yield to Aphanomyces

Given the wet springs and dry summers we’ve seen in recent years, Aphanomyces euteiches — Aphanomyces root rot — has become a real problem for pea and lentil growers. First confirmed in Saskatchewan in 2012 and then in Alberta in 2013, the disease has been slowly creeping across the country, destroying crops in its wake. Making […] Read more

Late season root rot is creeping into pea fields. Sarah Weigum

It sounds a bit dramatic, but the late season root rot that is creeping into Prairie producers’ pea fields feels like a betrayal. Besides being a profitable to grow, peas seemed like the “right thing to do.” I tend to feel smug when I hear of clubroot in a distant county, because I assume growers […] Read more
