Oil palm is credited for its superior nutritional qualities and broad range of industrial & applications. Being an important economic crop for many countries especially in Southeast Asia, there is much concern about various pests and diseases that attack oil palm around the world. One of the most devastating diseases that cause significant losses in oil palm production is the basal stem rot (BSR) disease, caused by pathogenic Ganoderma. To date no known cure and no effective control is available for BSR disease. In this study, Advanced Beneficial Microbial (ABM) system is employed to develop an enzyme-based biological product, namely ABM-OP1, which is capable to control BSR in oil palm. ABM-OP1 had shown visible effect and efficient in destroying more than 85% of internal Ganoderma mycelia through single spraying treatment on trunk cross sections. Injection strategy for ABM-OP1 was also established for its introduction to the target area with most active internal mycelia. This disease-specific product had shown excellent internal mycelia elimination efficacy, ranged between 80% and 96% on infected oil palms using trunk injection method. ABM-OP1 might serve as a hope for possible way to control Ganoderma infection, as well as avoiding further internal rotting by Ganoderma and prolonged palm productive life-span.
