Choose a cultivar with adequate blackleg resistance for your region... For individual site results consult the NVTonline website... Background: Blackleg disease can be minimised by a number of factors including sowing cultivars with high blackleg resistance, avoiding sowing in close proximity to last year's stubble and applying fungicides (see the current Blackleg Management Guide for details www.grdc.com.au)...

The large areas sown to canola in 2011 and the predicted increases in the area sown to canola in 2012 in southern NSW and northern Victoria will increase blackleg severity and increase the likelihood of yield losses... The aim of the work was to investigate the use of foliar fungicides on canola seedlings as an alternative or in addition to the application of a seed dressing for blackleg control in areas of high disease pressure... Results from the field experiments suggest that the addition of a seed dressing and the application of a foliar fungicide gave the best protection...

Identify the most appropriate methodology of single isolate screening of resistance genes in Australian oilseed Brassica lines... To successfully breed new blackleg resistant cultivars breeders need to know which resistance genes are already deployed, which are no longer effective (pathogen has overcome resistance) and which resistance genes are to be exploited... If resistance genes are overcome by the pathogen we need to be able to tell growers which cultivars are likely to be affected and which cultivars to avoid...

Barley Yellow Dwarf Virus can be a threat in all environments, and it is recommended that seed be treated with imidicloprid, or crops closely monitored for aphid infestation and sprayed ... In the circumstances using fertilisers that have a higher sulphur content, like MES 10 or Airseeder Superfect, can be beneficial... A fast track project was initiated to demonstrate and evaluate a range of management strategies that Twelve farms were surveyed across the western districts of southern Victoria that were considered suitable as potential trial sites based on grower and adviser recommendations...

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...
