To quantify the level and effects of sub-clover root disease in pastures across the south-east region of South Australia. It aims to understand the production and economic impact of root disease and, through the evaluation of chemical and cultural control methods, establish cost-effective solutions to manage these diseases.

• Seasonal conditions can affect the disease complexes that exist for sub-clovers in any season (eg. the drier summers in 2014 & 2015 would be expected to cause a higher incidence of Rhizoctonia, whereas the wetter season in 2016 saw Pythium sp., Aphanomyces sp. and Phytophthora sp. more likely to be the dominant diseases).
• Current sub-clover establishment management practices (knockdown herbicide, cultivation, use of Apron seed dressing and sowing newer varieties or those that are widely adapted to the region) appear to be reducing the risk posed by root disease across the region.
