    In vitro interactions between Rigidoporus lignosus, the case of white root disease of rubber and some potentially antagonistic fungi
    (Rubber Research Institute of Sri Lanka. Agalawatte, 1995) Jayasuriya, K.E.; Deacon, J.W.
    The modes of aaction of fungi potentially antagonistic against R. lignosus were assessed in vitro by studying their ability (a)to cause pre- or post-contact damage to R. lignosus hyphae in video taped interactions on thin purified water agar films and, (b) to displace the established pathogen from woody inocula. The most fungi were Trichoderma spp. which produced volatile or non-volatile inhibitors. Basidiomycetes such as Trametes sp. caused hyphal interface similar to that of Phlebiopsis gigantea, a commercial biocontrol agent of Heterobasidion annosum in pine stumps. species of Trametes and Aspergillus partially or completely displaced R. lignosus from previousley colonized woody inocula.

    In vitro antagonism caused by some species of fungi on Rigidoporus lignosus
    (Rubber Research Institute. Agalawatte, 1996) Jayasuriya, K.E.; Deacon, J.W.; Fernando, T.H.P.S.
    Fungi potentially antagonistic to rigidoporus lignosus were isolated from a) by placing soil samples on agar plates previously colonized by R.lignosus, or on trichoderma selective agar and b) from basidiomycete fruit bodies in rubber plantations.Modes of action of potential antagonists against R. lignosus were evaluated by in vitro methods viz: production of volatile or non-volatile inhibitory compounds and ability to overgrow colonies of R. lignosus an agar. Some trichoderma spp. were strongly antagonistic to R. lignosus in most of the tests. T. longibrachiatum (isolate DZE10) completely inhibited R. lignosus an agar by producing volatile inhibitory metabolites. Trametes sp. producing volatile inhibitory metabolites. Trametes sp. (isolates ISO16 KIR8) antagonized R. lignosus on dual membered plates.
