In the southern Philippines, tropical fruits such as durian, jackfruit and pomelo are high-value crops that offer smallholders the potential to generate income. Previous work has identified nursery hygiene, integrated pest and disease control, integrated crop management, and value adding and processing as major constraints to the development of these emerging industries. Similar issues affect the development of these industries in Australia. This project aims to address these major constraints, using jackfruit as a representative model, to build reliable supply chains for both domestic and export markets. Expected outputs include development of systems for the production of disease-free nursery stock, introduction of potassium phosphonate for disease management, availability of improved stock-scion combinations, improved management technologies to control and extend the fruiting season and processing options for jackfruit. The research is expected to improve livelihoods of smallholder tropical fruit farmers in the southern Philippines and enhance new industry development in tropical Australia.
