Yield losses increased from 18% to 99% in the hybrid canola ‘73-15RR’ and 26% to 86% in hybrid ‘1950RR’ when disease severity rose from 2 to 5 compared with plants with severities of 0–1. Understanding the yield loss relationship with blackleg severity will help agronomists...

Research conducted over the past decade set the foundation for today’s clubroot management practices. This research covered the potential of biofungicides/fungicides, cultivar resistance, and crop rotation for management of clubroot disease caused by Plasmodiophora brassicae. Synthetic fungicides ineffective The fungicides Allegro and Omega (fluazinam) and Ranman (cyazofamid)...

This Manitoba study found that nitrogen source did not affect canola yield, but fertilizer placement did. Fall surface application of granular urea and enhanced efficiency fertilizer products produced lower yield (13 bu./ac.) than spring surface applications of the same products. For spring applications, surface placement...

Redekop Seed Control Unit, an integrated reversible cage mill with blade system that provides Harvest Weed Seed Control, was assessed for volunteer canola control. Blade configuration in combination with chaff feeding rate did not affect volunteer canola control, which remained above 99%. Harvest Weed Seed Control...

This study validated the nominal economic threshold of 25 per cent defoliation. It also determined significant associations between landscape structure and flea beetle abundance, weather and flea beetle abundance, and plant density and flea beetle damage. As well, two flea beetle predators were confirmed. Flea beetles...

SaskCanola administered Growing Forward 2-funded blackleg research projects that concluded over the past year or so. Results from these studies make it possible for farmers to test for the predominant blackleg races in a field and use this information to make strategic decisions for the...
