If you can’t get enough sulphur for seeding, divide what you have across all your canola acres, then top up with an in-crop application of ammonium sulphate.Post-emergence sulphur can be applied up to flowering and still provide a yield benefit…

It can take a few days before you can accurately determine how many plants survived a heavy frost. Give the crop 3-4 days after a frost before making a reseeding decision… -
A week of moisture across the Prairies has delayed seeding. Canola seeded any time in May has a good chance of reaching maturity, so May 9 isn’t late, however growers……

Seeding is a priority for many growers this week, but fields with a large population of weeds, especially advancing winter annuals, should get a pre-seed burnoff. For annuals and winter annuals, glyphosate needs only 24 hours to get to the growing point and set the control process in motion. After a day, the crop can be seeded. For perennial weeds,… -
Growers could glean a couple useful tips about seedling survival by taking a plant count in last year’s canola stubble. It can also serve as a reminder to take seeding notes for each field. Record seeding rate, seed weight and seeding date for each field, and record weather parameters that will influence seedling survival — soil moisture (dry, moist, wet)… -
If flea beetles are already out and on volunteers given the conditions we’ve had, as soon as it gets warm, they will be feeding more aggressively… -
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. 2. Seed shallow. 3. Don’t cheat on the seeding rate, especially if seedling diseases have been a problem in past years… -
When the warmer weather returns, as is forecast later this week, canola still in the seedling stage that was seeded over 3 weeks ago may be at high risk of flea beetle damage. Also, dig down to look at the seed. A soft mushy seed is dead — likely from disease — and will not emerge…
