Most green seed issues result when heavy frost hits canola before the seeds mature. This permanently stops the chlorophyll-clearing process and locks in green. Nothing can be done to reduce this green. Drying can shrivel up green immature seeds, which might seem to have a benefit, but it does not reduce the green in mature seed. With high-green canola, farmers…

If identified early enough and small enough, patches of soil infested with clubroot-causing Plasmodiophora brassicae can be managed in various ways to reduce the spore load in those patches and prevent clubroot from spreading beyond that patch. This excerpt from a November 2018 Canola Digest article describes patch management techniques:…

Farmers who discover clubroot early and take action should be commended. Not singled out. Not blamed. If you’re the first to find it in an area, it might mean you’re the most observant scouter or that nobody else has been brave enough to report their infestations yet. By coming forward, you and your neighbours have a chance to talk about…

These definitions help answer questions such as: How can we lose a resistance trait? How does a clubroot-resistant (CR) variety work one year and not the next?…

Producers who are not currently registered for the Harvest Sample Program but who would like to take part in 2018 have until November 30 to register online. There is no charge to enroll, and registered participants have until December 31, 2018 to submit samples taken from their crops…

Canola Watch prefers to base its information on scientific research, but we don’t have a lot of information on these 2018 experiences: drying and storing very high-moisture crop, handling high-green canola. This survey is designed to collect on-farm experiences that we can share with readers. Agronomists and retails can provide answers based on their clients' experiences. We will not use…

What moisture level is too high to combine canola? How to prepare to handle high-moisture canola? How long can you store damp canola (>12.5% moisture)? How to reduce storage risk for high-moisture canola? How to add supplemental heat? How to estimate airflow rate (cfm/bu) through a bin?…

Canola that still has a lot of green seed might not de-green that much further. Green may have been locked in by frost and if more de-greening was possible, it probably should have happened already with the moisture over the past two weeks. When good harvest opportunities arise, the best bet at this stage of the season is probably to…

Getting crop in the bin is a bigger issue than residue management right now. Residue will be a factor in harvest because standing canola downed by snow will have to be combined close to the ground. That means more residue to churn through the combine and less residue to hold snow. Tough residue won’t chop and spread that well either…
