Pythium species, Fusarium species and Rhizoctonia solani – the “three amigos” – can cause seed rots, root rots and stem decay on young canola plants. Seed treatments are generally pretty good, but in the podcast below Krista Anderson from Bayer, Mark Belmonte from University of Manitoba and Autumn Barnes from the CCC explain the factors that can increase risks. They also describe management options (including rotation) that can keep these pathogens of the soil microbiome from rising up.

Seedling disease complex
Canola is vulnerable to a number of seed and seedling diseases, including those caused by Rhizoctonia solani, Fusarium species and Pythium species. However, in addition to effective scouting at the right time, there are some preventative and management options to deal with these diseases. A registered seed treatment with multiple fungicide active ingredients can minimize…
Moist soil increases seedling disease risk
The seedling diseases risk increases with moist soil conditions and with tight canola rotations. The three best management steps for canola in this situation are: 1. Use treated seed. Certified seed all comes treated, but if you’re tempted to use non-treated seed as a bulking agent, don’t bother. Seeds and seedlings from this seed will…
Look for seedling diseases and other emergence issues
Got canola emergence issues? Little canola plants are vulnerable to many different risk factors, including seedling diseases. Seed treatments are usually very good at managing the common seedling disease pathogens of canola, however seed, seedling and root rots can flare up under the right circumstances. Here are details about the three pathogens in the canola…
Slow emergence adds to seedling disease risk
Cold soils, frost and generally low air temperatures have slowed canola growth. Seedling diseases are starting to show up as fungicide seed treatments start to lose their effectiveness after a few weeks. No foliar sprays are available for seedling diseases, but growers should still dig and look at roots and stems to identify whether disease…
