After a frost, it can take a few days to accurately determine how many plants survived, and whether the stand is still uniform. Be patient before making any decisions. Check the whole crop the day after a frost and then again 3-4 days after a frost to assess the situation…

Canola is quite susceptible to water logging and shows a yield reduction after only 2-3 days in excessive moisture. Wait to see how the crop recovers before making decisions on reseeding or fertilizer top ups…

Growers will learn a lot from two field checks during the first few weeks after emergence. Scout fields 5 to 10 days after seeding when canola starts to emerge, looking for early threats. Then go back again two to three weeks after seeding to assess the stand…

1. Assess the disease situation. 2. Consider disease severity when choosing varieties. 3. Recognize which issues were agronomic versus environmental. 4. Evaluate variety performance. 5. Manage residue with the combine. 6. Identify weeds before making fall weed control decisions. 7. Manage volunteer canola. (Key is to prevent losses in the first place.) 8. Count stems after harvest. 9. Do a…

Growers in many regions are reporting canola fields that just don’t look as good as usual. Many are thin stands with weak plants and variable stages of maturity. Here are 10 most likely reasons…

Want to see how a foliar nutrient application helps a hailed crop? Leave a check strip. Want to see whether a novel treatment provided a return on investment? Leave a check strip. Growers can use strip trials on their own farms to test how a particular practice or product performs in a local environment. This information can then be used…

Early season hail rarely has an impact on canola yield potential. Hailed seedlings usually come back very well. If hail breaks off both cotyledons or snaps the stem, these plants usually do not survive. But even in these severe cases, while individual plants may die, a whole canola crop is fairly resilient to early season hail when it comes to…

The week after seeding is a good time to dig up seeds and seedlings to check for rots and blights. Disease damaged seed and seedlings die quickly, and may be gone within a few days, which is why this timing is important to an accurate diagnosis. While scouting for disease, also look for…

Start counting a week after seeding and repeat a couple of times over the following two weeks. Here's how…
