Papaya is an important and continually expanding crop in the Philippines, ranked 6th in terms of area planted and 5th in terms of volume produced. Previous work in the Philippines has highlighted the importance of the papaya disease bacterial crown rot (BCR), which can result in 50-100% of the crop being lost. The aim of this project is to increase the incomes and improve the livelihoods of smallholder papaya growers in the southern Philippines through the development of an integrated disease management strategy for the control of BCR and other diseases. The project will characterise the BCR organism, and develop and evaluate sustainable management practices for BCR and dieback diseases. Outputs will include development and dissemination of a package of integrated disease management strategies for papaya. This research will improve papaya production in the Philippines, and in Australia it will inform growers about managing dieback and improve capacity to prevent the entry and establishment of the exotic disease BCR.
