Pulse School: Assessing the culprit(s) causing a root rot problem

For parts of Western Canada, the rain keeps on pouring. Early wet conditions could be conducive to root rot problems in pulses. Fortunately, for three of the four main culprits —rhyzoctonia, fusarium and pythium, the plants will generally grow through the vulnerable early seedling stage if a seed treatment has been applied, notes Robyne Bowness-Davidson, pulse… Read more »

The Seedpod — Ep 11: Two Tests for Aphanomyces

Aphanomyces is a soil-borne water mold thatcauses devastating root rots in pulses, especially pea and lentil crops. Unfortunately for farmers, the aphanomyces spores can live in the soil for 10 years, and thrive under wet conditions. That means, not only has this root rot advanced rapidly across many areas of Saskatchewan and Alberta, but it’s… Read more »

Pulse School: Assessing In-Field Tools for Managing Aphanomyces (Do I Have to Wait Six Years?)

Taking a break from peas or lentils for six years is a tall order for fields where aphanomyces has been a problem. Are there in-field options or tools for managing this relatively new disease? Syama Chatterton, pulse crops pathologist with Agriculture and Agri-Food Canada in Lethbridge, has been conducting field trials across the prairies over the last two… Read more »

Pulse School: Pulse Crop Rotation Options in the Face of Root Rots

Tough to say and even harder to control, aphanomyces has the potential to significantly reduce pea and lentil yields, and can stick around in the soil for an extremely long time. It’s recommended that farmers not plant pea or lentil for five to six years if aphanomyces has been confirmed in a field, but that’s… Read more »

Pulse School: Improved Root Rot Resistance Coming for Peas

With wet growing conditions in many areas and high prices driving tight pulse crop rotations, the table was set for root rot to feast on pea stands in Western Canada this year. While one of the main culprits — aphanomyces — was first confirmed in Saskatchewan in 2012 and in Alberta in 2013, testing on the pathogen… Read more »

Pulse School: Deciding on a Second App of Fungicide

Round one of fungicide application is done, but it’s starting to wear off and conditions are still conducive for disease. Knowing what your peas and/or lentils are worth this year, do you take the sprayer out or hire a plane for a second fungicide application? It’s a scenario growers in parts of Western Canada are finding… Read more »

Pulse School: Is Your Seed Up to Snuff?

How confident are you that your pea and lentil seed is not limiting yield potential before you even put it in the ground? With rising acres leading to a shortage of certified seed, there are serious concerns about the quality of the seed that will be used this spring. Sarah Foster of 20/20 Seed Labs joins our own Kelvin Heppner… Read more »

Under the Microscope: Could Aphanomyces Be Lurking in Your Field?

While this growing season may have some pulse growers wishing Mother Nature would turn the water taps on, the past few seasons have been tough on pulse crops when it comes to root rots and seedling diseases. Particularly in 2013, farmers were stumped by pea fields hard-hit by “wet feet.” Turns out, there was a… Read more »
