If you don’t have clubroot, should you be planting clubroot-resistant canola?

Should a farmer who regularly practises a one-in-four-year rotation of canola in an area without confirmed clubroot be growing clubroot-resistant (CR) cultivars of canola? This was a question I asked at a canola agronomy meeting last November. At that time, I was describing my own farm and I thought the answer would be straightforward, but I received conflicting responses. One canola company representative said […] Read more

By Doug Moisey February 19, 2019

It’s time to face facts: the risks associated with clubroot have become far too great to ignore — no matter where you’re growing canola. In fact, we actually saw an increase of clubroot confirmations in 2018 So, why the increase? For starters, clubroot spores are moving from field to field. As well, use of canola […] Read more

Clubroot will vary depending on soil conditions. From left to right: <1,000 resting spores / severity rank 0, 1,000 resting spores / severity rank 1, 10,000 resting spores / severity rank 1, 100,000 resting spores / severity rank 2, 1,000,000 resting spores / severity rank 2.

Use best practices and management to keep it low and localized

By Lee Hart February 13, 2019

Infection of the legume host can take place at anytime in the season but is not obvious early in the year. The […] Read more

No-till and minimum-till systems both have agronomic drawbacks and advantages

By Doug Moisey January 18, 2019

No-till and minimum-till systems both have their advantages and drawbacks, especially when it comes to managing weeds, disease and insects in next season’s crop.

There are several key management tools producers need to apply to minimize the risk of clubroot either reaching a damaging level, and/or to reduce a heavy spore load of the pathogen in the soil to a tolerable level (about 1,000 spores or less per gram or teaspoon of soil will not affect crop performance). The […] Read more
