MORPHOLOGICAL CHANGES OF Ganoderma boninense MYCELIA AFTER CHALLENGED USING THIRAM, ZNO NPS AND LUCSIN
Basal Stem Rot (BSR) is an economically important disease which caused by Ganoderma boninense. The disease affects the oil palm production significantly, has led to major losses in the Malaysian palm oil industry. Numerous BSR management strategies have been documented in controling the disease, nonetheless, with no conclusive remedy. Current study, in vitro investigation of antifungal effects of thiram, ZnO NPs and lucsin on the morphology of G. boninense using Scanning Electron Microscope (SEM) has been done. Observation under SEM confirmed morphological disruption of the G. boninense mycelia treated using thiram where abnormality, distorted and damaged hyphae had resulted in lower density of fungal mat. There was also evidence of the lower density of fungal mat as well as malformation structures of G.boninense hyphae after being treated by ZnO NPs. Minor ruptured was found on the hyphae and the hyphae branch were shriveled, distorted and flattened after challenged with Lucsin.
