To date, G. boninense remains the greatest threat to the oil palm plantation due to its enormous devastation towards palm trees by causing an incurable basal stem rot (BSR) disease, after invading and colonizing the tree. This soil-borne pathogen is a parasitic and saprophytic fungus that attacks the living tissue and decomposes the bole or lower stem of palm tree through colonization on the root surface. The gradual decay of roots, bole, and trunk tissue caused by BSR obstructs the flow of water and nutrients to the upper parts of mature oil palm trees. This leads to symptoms like frond wilting, yellowing, and eventually, the collapse of entire stands.
