BrettYoung offers canola varieties designed to defend against blackleg, delivering high yields and strong, multi-gene resistance. This article covers the benefits and features of BrettYoung’s DefendR®-rated blackleg canola varieties, highlighting their performance and disease resistance.
Why Blackleg Matters
Blackleg is a threat to canola production. It is caused by fungal pathogens that infect plants and move into the stem. Infected plants experience stem rot, which prevents absorption of nutrients from the soil.
Additional Diseases of Concern
- Sclerotinia
- Clubroot
- Fusarium (to a lesser extent)
