Abstract
Basal stem rot BSR caused by species of Ganoderma has been recognised as a serious disease of oil palm Elaeis guineensis for over 80 years and has caused severe economic loss in Malaysia and North Sumatra especially during the last 30 years. It is also becoming increasingly important in the newer plantings of Papua New Guinea and the Soloman Islands. One estimate of 38 million US has been quoted to be lost annually to the Indonesian economy alone assuming only 1 disease incidence but in reality incidence of the disease is much higher. The symptoms of BSR are well known but the biology and epidemiology of the pathogen less so -the actual mechanisms of infection the origin and longevity of inoculum within the soil and the role of basidiospores in the disease cycle remain unclear. In addition the taxonomy of the whole genus is currently regarded as somewhat chaotic with poor species identification in the past resulting in the description of over 250 species. Use of stable morphological criteria and increasingly the use of molecular techniques should help clarify this situation. Management of the disease currently involves cultural practices especially at replanting time which are very costly. In the future the use of resistant material is likely to become important part of an integrated approach but in the shorter term understanding more of the biology and spread of the pathogen is important to the industry to allow them to make decisions about control methods. Management of this disease is crucial to any agenda for sustainable oil palm growing in this region.
