No foliar sprays are available for seedling diseases, but growers should still dig and look at roots and stems to identify whether disease is the cause for weak plants. Understanding what contributed to seedling disease in fields this year may help plan for better results in your canola fields next year…

No research has been conducted to show the best ways to break up crusting and free the crop. If a few plants have emerged, it may be best to leave them be. One to 2 plants per square foot are better than none…

Growers who broadcast canola with a cut rate of fertilizer (or perhaps no fertilizer in the case of aerial seeding) may want to wait for crop insurance to approve the stand before investing in a fertilizer top up. Evaluating the stand will also be necessary to set a reasonable yield target for fertilizer applications…

With cool temperatures, flea beetles have moved down to the stems and undersides of leaves to feed. Thresholds for stem feeding are lower than thresholds for leaf feeding, so make sure to scout the whole plant. A plant cut off represents 100% leaf area loss for that plant…

Small and vulnerable canola plants face many threats during their first three weeks. The crop may need your protection to get through these stages with its top-end yield potential intact. Canola growers are encouraged to walk their fields a couple times a week — or more — until plants are firmly established and growing strong…

With most canola seeded and starting to emerge across the western Prairies, scouting becomes a top priority. This is a canola crop’s most vulnerable stage, and through scouting you can……

Peace (B.C. and Alberta): Seeding is 90-95% complete. Emergence is generally good, but some canola seed is stranded in dust and waiting for rain. Flea beetles are all over the……

Canola is most fragile during the first 21 days after emergence. The small plants are highly susceptible to flea beetles, cutworms, seedling diseases, weed competition and various other threats. Scouting may be required every day for at-risk crops, especially if a threat such as flea beetles seems to be building. At a minimum get out to each field a couple…

You can often tell the condition of a crop the day after a frost. It may have survived without any damage, in which case you may not have to worry. Or, if most of the plants are black and bent over, it may be clear that serious losses have occurred. But does that mean the field should be reseeded? The…
