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…

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…

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… -
With fields too wet to seed, growers in Manitoba and parts of Saskatchewan may be tempted to leave volunteer canola and harvest it as a crop. There are many reasons to avoid this, and very poor yield potential is just one of them…

After broadcast seeding, including seeding by plane or helicopter, fields must be harrowed to loosen the soil surface and provide seed to soil contact. Canola seed is very light and does not embed into the soil, even if dropped from an airplane at high speed…

Frost hit many areas of the Prairies again on the weekend. Some areas in central Alberta reported -8 C. This followed a frosts on a couple nights last week. Wait 3-4 days to see if the crop recovered before making a reseeding decision, and wait to make sure weeds are actively growing before spraying… -
It can take a few days for young canola plants to recover after a frost. Even if damage looks severe, give the crop a few days to see if it will recover before considering whether to reseed. Weeds also need to start growing again after a frost before a spray will provide strong efficacy…

Growers wondering when is too late to seed canola should consider these 4 factors: maturity of the variety, average date of first fall frost, crop insurance deadlines, and profit potential of option crops…
