BUNCH rots, young vine decline and vine trunk diseases will be targeted in this project which will build on valuable research work already carried out at the NGWIC. The aims include improved identification of vine diseases, development of models to predict outbreaks and determination of the most effective controls. It will also examine influences in vine fungal diseases and develop vineyard soil tests to predict replant problems.
The project team will conduct disease surveys on a range of varieties in vineyards across key NSW growing regions. Biological and non-biological environmental stress factors that influence the susceptibility of grape vines to disease will be identified. Management strategies to reduce the impact of critical stress factors will be established. Expected outcomes include improved detection and identification of wood and bunch diseases and reduction of bunch rot organisms in vineyards.
The project will provide a benchmark for the incidence of young vine decline in NSW and identify the principal mode of infection. It will also present an economic analysis of the effectiveness of the proposed management strategies and disease prediction modelling.
