This project is developing integrated pest and disease management (IPDM) tools for citrus black core rot, which causes internal rot and bitter flavours in infected fruit that is often undetected until it reaches the juicing plant or kitchen bench. Black core rot is a significant and emerging issue in southern citrus growing areas.

This project proposes to better characterise the Alternaria species causing the problem and unravel the disease cycle, including sources of inoculum and timing of infection, so that new options can be tested that integrate existing and new chemical, cultural and biological tools. Throughout the project, a post graduate student will be trained in all aspects of field pathology to increase the future research capability of the Australian citrus industry.
