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…

Flea circus. Flea beetles love warm weather and fresh young canola. When scouting, assess the whole crop, not just field margins, and spray if leaf loss exceeds 25% for most plants and feeding continues. Efficacy effort. Emerging canola is not highly competitive, yet. To get the most out of weed control, follow efficacy tips specific to products for each HT… -

Canola is advancing quickly, often emerging in 5 days and starting to sprout its first true leaf in just over a week. Flea beetles are also out in big numbers — enough to warrant a few walks through each field. Seed treatments will provide 3 to 4 weeks of protection for canola that emerges within a week of seeding. Flea… -
Weeds are coming up strong. As part of the Canola Council of Canada’s Keep It Clean campaign, we remind growers to use only registered pesticides when required. Refer to product labels for proper use instructions. Here are strategies to improve weed control results for each HT system: —Liberty LInk: As a contact herbicide, Liberty is recommended to be applied as… -
Canada’s Pest Management Regulatory Agency (PMRA) permits “unlabelled” tank mixes as long as products in the mix are used under the following conditions: 1. Each tank mix partner is registered for use in Canada on the crop of interest. Note that just because products have similar actives or are generics does not mean that they are registered for use on… -
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…
