Two Acacia seed orchards, one each of A. mangium and A. auriculiformis, in Central Java have suffered high losses from root rot associated with a species of Ganoderma that is distinct from G. philippii, which causes extensive losses in A. mangium plantations in Sumatra and Kalimantan. Ganoderma steyaertanum was consistently isolated from roots of affected trees in the Javanese orchards and pathogenicity was confirmed by satisfying Koch's postulates. The mode of spread of the pathogen was examined by analysing the distribution of tree deaths in the A. mangium seed orchard and conducting somatic incompatibility tests among G. steyaertanum isolates from diseased trees. Spatial analyses indicate that, after an initially random disease distribution, the pattern of tree deaths was clustered. This is consistent with spore colonisation of thinned stumps followed by vegetative spread through root-to-root contact, as has been observed for other root pathogens such as Heterobasidion annosum. Somatic incompatibility tests demonstrated high genetic variability of the pathogen with root-to-root spread also confirmed.

This study describes and identifies the fungi associated with root-rot disease in Eucalyptus pellita, associated anecdotally with a species of Phellinus. Macro-and microscopic morphological observations and DNA analysis were used to identify sporocarps and fungal cultures growing from symptomatic root samples. Investigation of 12 sites in Central Sumatra revealed that red root-rot disease caused by species of Ganoderma (most commonly Ganoderma philippii) was as prevalent as root disease caused by Phellinus noxius. The study also detected the presence of several potential fungal agents of root rot at any one site. Fungal signs such as absence/presence of sporocarps were a poor indicator of root-rot incidence in stands. Instead, fungal isolation from infected roots was essential to obtain accurate identification of active pathogens.

The rapid emergence of Acacia mangium as the key industrial plantation species in Indonesia has been followed by the equally rapid emergence of red root rot (Ganoderma philippii) as its potential nemesis. As a consequence, and on severely affected mineral soils in equatorial tropical environments in particular, A. mangium may no longer be capable of producing commercial yields after three rotations. In this experiment, 100-tree plots were established in commercial plantings of A. mangium at five sites which represented the range of growing conditions used for plantation establishment in Indonesia. Repeated monitoring at approximately 6-month intervals of above-and below-ground variables was used to explore relationships between measures of tree health and root rot. Crown colour and density were poor predictors of either the presence or severity of infections. Tree mortality increased more or less linearly with time and led to the progressive coalescence of initially discrete disease gaps. The average rate of disease development was about 0.3% per month, and average time from infection to tree death was conservatively estimated at around 1 year. Trees with more than four dead/missing neighbours had a >50% chance of being dead by the following monitoring. By the end of the monitoring period >40% of trees were classified as dead/missing, although this value varied from 20 to 70% depending on site, tree age and rotation. Canonical discriminant analysis correctly allocated >90% trees into their correct group on the first monitoring and similarly classified whether trees would be dead or missing in the following monitoring.
