Abstract:
Oil palm is an economically important crop in Thailand with its cultivation concentrated in the southern provinces. Diseases and disorders are the major cause of yield and quality losses to oil palm plantations. The objective of this study was to provide updated information on and to evaluate the geographical distribution of oil palm diseases and disorders in southern Thailand. A survey of oil palm plantations in southern Thailand was conducted during the years 2010-2012, to record diseases and disorders of the crop. This revealed a variety of oil palm diseases, including algal, bacterial and fungal diseases; macro and micronutrient deficiency problems and genetic disorders. Three diseases, namely brown germ, Curvularia leaf blight and Ganoderma basal stem rot, were classified as major diseases during the survey period. Brown germ and seed rot were the most destructive, affecting the seed germination process. The fungi that were frequently isolated from the collected samples belonged to the genera of Aspergillus spp., Fusarium spp., Mucor spp., Penicillium spp., Schizophyllum commune and sterile hyphomycetes. Curvularia leaf spot caused by C. oryzae was widespread at nursery seedling stage, while the basal stem rot caused by G. boninense was very destructive at the fruiting stage in the field. This report describes the incidence rates, disease symptoms and the fungi isolated from symptomatic tissue.
