As earliest canola crops start to flower, the annual sclerotinia stem rot management conversations begin. This article describes factors that increase risk and reduce risk.
After the hail
How many plants recovered? Are they at early stages and at risk of heavy blackleg infection? What is the crop nutrition situation?
Scouting 7 to 21 days after seeding: What to look for?
With warm soils, decent moisture and 1” seeding depth, emergence can occur about a week after seeding. If emergence is slow or patchy, scout to find out why. The first 21 days are critical to a successful canola crop.
Photography tips for agronomy
Photographs can be a valuable diagnostic tool, but they have to be in focus, taken from various angles and come with details on field conditions and location.
Clubroot, wet springs and mud
Moving soil means moving clubroot. Because more soil clings to machinery in wet conditions, wet springs will increase the risk of clubroot movement.
Biosecurity for field crops: Why and how?
Biosecurity is something that livestock and horticulture producers have used for years to keep diseases from spreading to their barns, greenhouses and orchards. It is time for broad-acre crop producers to think biosecurity, too.
Quick comparison: Blackleg, clubroot, sclerotinia stem rot
Use this quick-reference table to compare key distinguishing features, mechanisms for spread, and management options for blackleg, clubroot and sclerotinia stem rot.
Saskatchewan ramps up random clubroot survey for 2018
Saskatchewan wants to increase its understanding of the distribution of clubroot in the province. The Ministry of Agriculture will conduct an extensive clubroot survey in the highest risk regions of Saskatchewan, which will include (1) areas in close proximity to clubroot infested areas along the Alberta-Saskatchewan and Saskatchewan-Manitoba borders; (2) high canola production areas; and (3) regions with favourable environmental conditions.
