Exploring hidden economic losses in sub-clover pastures locations
Aims

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.

Key messages

• Sowing late into a high disease burden may offset any benefits of varietal disease resistance or the benefits of chemical control methods (i.e. seed treatments).
• Seasonal conditions can affect the disease complexes that exist in any season (eg. the drier summers in 2014 & 2015 would be expected to cause a higher incidence of Rhizoctonia, whereas Pythium sp., Aphanomyces sp. and Phytophthora sp. are likely to be more dominant in wetter seasons).
• Varietal differences were observed in establishment and persistence, however it is yet to be determined if this was due to root disease tolerance.
