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...
