Blackleg is a sexually reproducing pathogen that will overcome cultivar resistance genes. Fungal spores are released from canola stubble and spread extensively via wind and rain splash. The disease is more severe in areas of intensive canola production. Blackleg can cause severe yield loss, but can be successfully managed. DuPont Pioneer Canola Research Scientist Dr Ray Cowley discusses Pioneer’s proactive and integrated approach to giving Pioneer® brand hybrids the best defence against Blackleg.
