The Canola Council of Canada has produced four videos showing how beekeepers and canola growers can work together. Click the image above to see the video called "Canola and Bees: A sweet relationship."…

Carpet of weeds. It seems like they’re all emerging at once, as shown in this photo from Anastasia Kubinec with MAFRD. Early control significantly lowers the economic risk. Broadcasting live! Broadcast seeding comes with higher risks, but it covers a lot of acres fast. Got tips to share? TKO for TSW. We’re not saying seed weight isn’t important, but many… -

Three questions: 1. Neil Harker, research scientist with AAFC in Lacombe, Alberta, says to provide “high yield protection” weed control should ideally occur before the ______ stage of the crop. 2. Integrated weed management uses various methods to keep weeds below economically-damaging levels. Of the following four points, three are proven principles of integrated weed management. Which one is NOT?…

More growers may have skipped the pre-seed burnoff this year — given that weed emergence was delayed with the cool start to spring and because growers wanted to get seeding. But the weeds are coming. Warmer temperatures and good moisture have inspired emergence of “carpets” of weeds in some fields. These weeds will have a tremendous impact on canola yield…

With an average seeding rate of 5 lb./ac., an average thousand seed weight (TSW) of 5 grams, and 50% seed survival rate, the result is only 5.2 plants per square foot. This doesn’t leave much margin for error — especially given the ideal target is 7 to 10 plants per square foot. Seed with a lighter TSW can improve your… -
This graph shows that a higher seeding rate that will ensure a stand of at least 60 plants per square metre (6 per square foot) will mature a lot earlier than a stand with 20-40 per square metre. A higher seeding rate is just one way to reduce the days to maturity for a late seeded canola field… -
Growers face many weed, insect and disease management decisions throughout a growing season. In many cases, these applications provide a clear return on investment. In other cases, they do not. Here are a few examples where applications have a very low chance of providing a return… -
High cereal yields last year mean more residue issues this spring. If the drill cannot cut through or dig under the residue to place seed into soil, then some sort of residue management may be the lesser of two evils. We ran a survey the past two weeks asking Canola Watch readers for their thoughts on effective spring management for…
