| Summary: | Basal stem rot (BSR) caused by Ganoderma spp. is a disease of
economic importance in oil palm in Malaysia. Although much is known
on the occurrence of this devastating disease, fundamental studies on
it and its pathogen are rather limited. At present, there appears to
be ambiguity in the identity of the causal organisms: there is
difficulty in getting oil palms to be artificially infected and that
control measures advocated are largely inadequate to contain the
disease. Present studies are thus focused on answering these issues.
An assessment of the BSR situation on selected estates was also carried
out to assist in the understanding of the disease.
The assessment carried out showed that serious incidence of the
disease was "confined to coastal and riverine estates. However, the
disease can now be seen to occur in a few in land estates albeit
sporadically and at very low incidence. It was demonstrated that
previous crops did not necessarily dict ate significant incidence of
BSR. The underplanting technique and certain soil types can predispose
plantings to much higher BSR incidence. |
