"ASSESSING THE ECONOMIC IMPACTS OF PHYTOPHTHORA DISEASE CONTROL STRATEGIES ON THE PROFITABILITY OF JACKFRUIT PRODUCTION IN REGION VIII, SOUTHERN PHILIPPINES"
by Preciados, Lemuel


Abstract
Jackfruit is a very popular domestic fruit in the Philippines. It has a wide distribution and cultivation being grown throughout the country. Jackfruit decline is a major constraint to jackfruit production in the Eastern Visayas where it is a flagship commodity. In some areas, up to 90% of jackfruit trees are reported to be affected by decline syndrome manifested by leaf yellowing and drop, girdling stem lesions and rot, and eventually wilting and death. Since the commencement of the project, a phytophthora species have been identified as the cause of a severe decline on jackfruit in Leyte and Samar in the Eastern Visayas. Despite knowledge of the causal organism and the availability of management strategies, the dissemination and implementation of management options have been a problem across the region with few farms practicing best management strategies. The collaborative research funded by Australian Centre for International Agricultural Research (ACIAR) entitled, Integrated Management of Phytophthora for Durian and Jackfruit is developing strategic technologies for integrated disease management practices that will reduce yield loss associated with the disease, improve fruit quality and ultimately improve farm income. In this paper, the potential impact of the effective management of phytophthora control research recommendations is discussed. It is estimated that approximately 57.5% of 578 ha jackfruit area in Region VIII are affected by phytophthora. The key management practices recommended were also identified which includes; the construction of drainage canals, mounding, pruning, sanitation, and application of a new chemical (Agrifos) through trunk injection. A combination of chemical application and improved cultural practices are expected to offer farmers the most effective method of controlling the disease. Preliminary research has indicated that effective management of phytophthora can significantly reduced yield losses by approximately 22% per hec...
