- ABSTRACT The experiment was aimed to isolate and determine the pathogen of white root rot of Acacia mangium Rrilld., and to select Trichoderma isolates for suppressing the pathogen biologically. Crotalaria juncea L. was used as indicator plant in the pathogenicity test. Identification of the pathogen was done by comparing the morphological characteristic of the pathogen with those of the same disease isolated from rubber tree. The results showed that the pathogen of white root rot disease of A. mangium is Rigidoporus microporus. Of the 15 Trichoderma isolates showing ability to inhibit the pathogen in vitro, three isolates were found as promising agent for biological control of the pathogen. They were T27 isolate (T harzicznum) from elephant dunk, T7 (Trichoderma sp.) from Silva Gama Jambi and T79 (Trichoderma sp.) from PROMOT product. Additional experiments, including ecobiology studies, formulation of the inoculum, and the compatibility of the biological agents with other method for controlling the disease, are needed before the biological agent can be tested for their ability to control the disease in field condition. Key words : Trichoderma, white root-rot die:Pace, biological control.
