Abstract

Rhizoctonia bare-patch (R. solani AG8) is a major problem across WA's cereal growing regions and is estimated to reduce WA state-wide cereal yields by 1 % to 5% annually. Australia has one registered fungicide for use on seed which claims to suppress rather than control the disease. Current management practices to minimise the impacts of Rhizoctonia bare-patch in WA are combinations of, cultivation with fungicide seed-dressing and adequate nutrition. Alternative fungicides and/or delivery methods (such as liquid injection) would provide greater flexibility for management of Rhizoctonia bare-patch.

Our aim was to determine the efficacy of current management options to control R. solani and the future options which will become available during the next few years.
