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.
