•   While scouting for disease and insects, take time to assess the stand. If the stand is spotty and thin, be more conservative with thresholds when protecting the crop from insects, diseases and weed competition. Also, recording the average number of plants per square foot will help growers improve seeding methods for 2011. Stands of……

  • Environmental issues continue to dominate canola production across western Canada. Cool daytime temperatures with unseasonably cold nighttime temperatures occurred across the Prairies last week and over the weekend. All regions reported frost on multiple occasions with some areas experiencing frost four times last week. The most severe frost happened Friday night/Saturday morning where temperatures ranged……

  • Poor growing conditions due to the cold weather and repeated frosts prevailed across western Canada again last week. Canola growth and development was stalled. Canola ranges from cotyledon to 4-leaf stage and is delayed by at least two to three weeks. In Manitoba, Growing Degree Days (GDD) to date range between 40 to 60% of……

  • Frost was widespread all across western Canada last week. From all reports, crop damage is quite variable – both within an area and within a single field. This is expected because many variables will affect a crop’s ability to withstand frost (duration of the frost, crop staging, crop residue, low lying areas, crop vigor, etc.)……

  • To evaluate a field, walk an X or W path across the field and note all plants that will survive in a 1/4 m2 (3 ft2) area every 20 paces. This should be 50 to 100 samples. Record an observation from each sample. Calculate the percentage of the field that has adequate plant recovery. The……

  • Before making re-seed decisions consider the following: Take a close look. Get down, way down, at ground level and look for signs of recovery. A plant with a green, intact growing point can still continue to grow. A magnifying glass will help zero-in on the tiny plant parts. Scratch around and scrape back crop residue……

  • There are reports of macronutrients and micronutrients being foliar applied to frosted, stalled crops to give the plants a boost. Canola Council of Canada agronomists are not aware of any scientific research to date here in western Canada that supports the economics of this practice. However, if growers do apply a foliar application, they should……

  • Re-assess the maturity of the chosen variety. It may be getting too late to plant longer season varieties based on the frost-free period remaining. If necessary, ask a local retailer to suggest other suitable varieties for the area. Keep crop insurance deadlines in mind. The crop insurance seeding deadline for Saskatchewan is June 20. In……

  • Canola fields with low plant densities are more vulnerable to losses from insects, weed competition and environmental stresses such as fall frosts. Crops with low plant densities need to be managed more intensely. More frequent and intensive scouting for pests (insects and weeds) is critical because any losses are more likely to reduce yield. Action……
