WESTERN, NORTHERN AND SOUTHERN REGIONS QUANTIFY THE RISK, PADDOCK BY PADDOCK Blackleg can cause severe yield loss, but can be successfully managed... If you have: high or increasing levels of blackleg in your crop (from monitoring disease levels each year); used the management practices outlined in Step 3; and sown cultivars from the same resistance group in close proximity (within 2km) for three or more years, then sow a cultivar from a different resistance group (see page 4 - Blackleg Resistance Groups)... To facilitate the process, all cultivars have been placed into groups (A to H) based on their resistance genes inTable 3...

The blackleg fungus, Leptosphaeria maculans, has a high propensity to overcome resistance in Brassica napus (canola) cultivars... If you have a blackleg problem and are growing a susceptible cultivar your first action should be to change to a cultivar with higher levels of resistance... The best policy is to monitor the level of blackleg in your cultivar on your farm, if you observe the level of disease increasing then switch to a different group...
