Developing knowledge and management of Strawberry Red Leaf Disorder

This research project conducted by the Department of Agriculture and Fisheries (DAF) and the University of Queensland (UQ), and co-funded through Hort Innovation, has led to the identification of potential causal agents of the strawberry Red Leaf Disorder (RLD). A better understanding of the spread and economic impact RLD has on the commercial Queensland (QLD) strawberry industry has resulted. RLD is characterised by reddish/maroon interveinal discolouration of the leaves and typically reduces plant vigour and yield. RLD is currently limiting the fruiting productivity and plant health of the major cultivars grown in QLD. Investigations into potential causes of RLD by DAF and UQ, have found no obvious single causal agent, suggesting that the disorder and mechanisms behind its transmission may be quite complex
