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 reason for the confusion — a new and not well known seedling disease had shown up in Saskatchewan fields: aphanomyces.

Unlike more common root rots, there is no seed treatment to protect against aphanomyces, though a product did receive an emergency registration this spring for Western Canada. How do you know if you have it, and what can you do about it?
Testing, of soil or of root tissue, is the only way to confirm if the die-off and discolouring you’re seeing in your field is aphanomyces. To explain when to scout and how to sample, we’re joined by Sydney Vos, with Biovision Seed Labs, for this aphanomyces-focused Under the Microscope.
