Induced Biochemical Changes in Ganoderma boninense Infected Elaeis guineensis Seedlings in Response to Biocontrol Treatments

Despite massive economic contributions to Malaysia, the oil palm industry faces devastating threats from basal stem rot (BSR) disease. An array of treatments was designed evaluate potential biological control agents (BCAs) as a single and combination applications in greenhouse study six months. Oil enzymes, phenolic content, metabolite induction BSR-diseased seedlings were also assessed response treatments. In study, treated with Trichoderma asperellum (UPM16) demonstrated highest disease reduction (DR) (57.2%). Peroxidase (PO), lignin, total content (TPC) evaluated. Treatments on Ganoderma-infected Bacillus cereus (UPM15) exhibited reading all assays. Gas chromatography-mass spectrometry (GC-MS) analysis profiled phenol, 4-2-aminoethyl- most abundant detected B. T. (BT). Both BCAs complimented huge mitigating BSR diseases palm. However, excessive chemical application BSRs negatively impacts biodiversity human population. view this, studies are crucial selecting counter sustainably. Biological would be an ideal alternative sustainable method for controlling
