Abstract: (105 Views)
Ganoderma boninense Pat. is a persistent soil-borne pathogen that causes significant losses in oil palm (Elaeis guineensis Pat.) productivity. In this study, we evaluated the antifungal activity of volatile organic compounds (VOCs) produced by a fungal isolate, later identified as Paraconiothyrium archidendri F10, against G. boninense. The isolate was identified based on ITS-rDNA sequence analysis and BLASTn results. VOCs produced by P. archidendri F10 were found to inhibit G. boninense mycelium growth by up to 55.8% in four days, with the mycelium exhibiting wavy, non-smooth, and wrinkled morphology, abnormal branching, fused, defective hyphae, and lysis from within. The major VOC components were esters, with 7,9-ditert-butyl-1-oxaspiro[4.5]deca-6,9-diene-2,8-dione being the most abundant (16.72%). The other top-ranking components were 2-O-(6-ethyloctan-3-yl) 1-O-hexyl oxalate (8.71%), methyl heptadecanoate (8.66%), and butyl acetate (5.66%), with minor components comprising less than 5% of the total VOCs. Our findings suggest that P. archidendri F10 has potential as a biofungicide for controlling G. boninense in the field.
