Abstract
Of the problems confronted by commercial forestry in western Indonesia, root-rot diseases of
exotic plantation Acacia mangium and, more recently plantation Eucalyptus pellita, are the
most intractable and damaging for the industrial pulpwood industry. For both acacias and
eucalypts, identification of the main causal agent of red root-rot as Ganoderma philippii was
assisted by species-specific PCR tests for G. philippii and G. mastoporum. Phellinus noxius
was also found to be pathogenic on both. Extensive monitoring has shown that mortality
increases more or less linearly with time at an average rate of about 3% per month. Average
time from first observed infection to tree death was conservatively estimated at 10-11
months. Several options are potentially available for disease control, but as yet no reliable
system has materialised. Seeking ways of managing inoculum load currently offers the only
way forward for containing red root-rot until reliable biocontrols are developed.
