As canola harvest wraps up for another season, it’s an important time for growers and agronomists to get out into fields and scout for disease.
Walking fields in the weeks after harvest helps paint a picture of what diseases may be lingering in the soil or crop residue, which can be important when considering a future crop plan.
Sclerotinia and blackleg are the key culprits on the radar when it comes to fall scouting, as they often remain in the soil and stubble, and can be found by clipping open stems.
As Lyle Jenson of Agro Plus Inc explains in this Canola School episode, signs like discoloured stems, or the appearance of sclerotia bodies indicate that sclerotinia and blackleg were already active prior to the combine passing through the field.
“It’s always a good idea to have an idea of what we’re going to be seeing years down the road,” he explains. “By examining stubble and uprooting plants after harvest, scouting can identify the presence and severity of these diseases.”
