Ganoderma boninense Pat. is the causative agent of root and bole rot disease of coconut. Hyphae of Trichoderma viridae were always present in the basidiocarp tissue of G. boninense. Attempts to separate T. viridae from G. boninense by culturing basidiocarp tissue on agar media in the laboratory were not successful. Investigations using slide culture techniques clearly showed that T. viridae formed coils around the hyphae of G. boninense and at the points of coil formation hyphal deformations were observed. These suggest that T. viridae may have potential as a bio-control agent against G. boninense.
