    Some effects of isolates of Trichoderma on Rigidipourus lignosus
    (Rubber Research Institute. Agalawatta, 1991) Wijesundara, R.L.C.; Jeyanathan, S.; Liyanage, N.I.S.
    Seven forms of Tricoderma were isolated from soil obtained from rubber plantations. All the isolates secreted compounds inhibitory to the growth of Rigidiporus lignosus the causal agent of the white root disease of rubber. Further, the Trichoderma isolates interacted with the hypase of R. lignosus, the interaction resulting in harmfull effects on R. lignosus hyphae. Of the isolates examined T. Koningii isolate IV and T. harzianum appear to be very promising as potential biocontrol agents
