Manitoba has a few confirmed cases of clubroot in 2015. One field with galls was found in the R.M. of Pembina, and fields with galls were found in the Swan River Valley…

Western Canada has made great strides in adopting minimum tillage practices that save time and diesel fuel, improve soils and improve sustainability scores. Here are factors to consider before choosing the tillage option… -
Many things can cause yields to be lower than expected. Crops that run out of nutrients may have significant biomass but smaller or fewer seeds in the pods. Moisture and…… -
Moist conditions mean more soil clinging to machinery wheels. This increases the risk of moving clubroot as well as weed seeds and insect pupae around the farm. With the discovery of a potential new clubroot pathotype, growers will want to take time to sanitize equipment between fields…

Three major stem diseases — blackleg, clubroot and sclerotinia stem rot — are more easily identified in the weeks leading up to harvest. Areas of the field with prematurely ripening plants and excessive lodging are signs that any one of these three diseases could be present… -
Buying used equipment from a clubroot area can create an unexpected transfer of the disease. We heard this week of a grower from northern Alberta who bought a used combine from a known clubroot area. The grower was surprised at how much soil was on and inside the combine, and this soil very likely contained clubroot spores…

Erosion of clubroot resistance is showing up in fields across central Alberta. Recent research by Alberta Agriculture and Rural Development (AARD) and the University of Alberta (U of A) has……

Growers can have soils tested for low-level presence of clubroot at Manitoba's new Pest Surveillance Initiative (PSI) molecular detection laboratory. The lab processes and analyzes soil samples for presence of clubroot at very low levels, prior to noticeable plant symptoms,… -
The best management option left is the four-year rotation. Discovery of different clubroot pathotypes in central Alberta will change the rotation plans for some growers. No current varieties have strong resistance to these pathotypes. If growers have used resistant canola two or three times already on fields that were infested with clubroot, these fields are at high risk for having…
