Sclerotinia stem rot infection is being found lower down the plant in many fields this year. Some fields are lodging because of sclerotinia infection. In some cases, sclerotinia infection is right near ground level, which is where blackleg is also found…

Harvest plant counts can help growers determine if their seeding was adequate to reach the crop’s yield potential. A compilation of stand establishment research shows that canola generally needs at least 4-5 plants per square foot to reach its yield potential. But is this true for all varieties, all crop inputs packages, and all growing conditions? We don’t know. Growers…

Growers are still seeing some insects in their canola crops, including a higher than normal presence of flea beetles. Answers to the following three questions may help with management decisions…

If late season hail damages pods, then these pods have a higher potential for shattering as they dry. Swathing early to save these pods may not be worthwhile if these pods represent only a small percentage of the yield potential of the crop…

Canola binned hot, even if it has low moisture, low dockage and low green, should still be put on aeration. This will even out the temperature throughout the bin, and help remove some of the moisture from respiring seed. Even at low moisture, air movements within the bin could concentrate this moisture…

Serious disease infections become more obvious as fields get closer to harvest. Whitened diseased and dying plants are in stark contrast to the healthy light green plants around them. Take time now to identify which disease is responsible. This is essential for management next year. Late canola fields may be at continued and higher risk for bertha armyworm feeding, especially…

Growers can lose up to 5 bu./ac. of canola during harvest, with many of those losses occurring as canola enters and exits the combine. Combine losses should be less than 1 bu./ac., and hopefully more like half a bushel. Here are the top 10 tips to keep combine losses to a minimum…

Research conducted by the Canola Council of Canada over approximately 28 site-years indicates that significant yield increases can be achieved by waiting until 50-60% seed colour change on the main stem before swathing. Swathing at 50-60% SCC resulted in 8% more yield than swathing at 30-40% SCC, 12% more yield than at 10-20% SCC, and 19% more yield than swathing…

The optimal swath timing for canola yield and quality is when 60% of seeds on the main stem are showing some colour change. Seed colour change (SCC) is considered any amount of yellow or brown on the seed…
