Chaetomium globosum, Gliocladium virens and Trichoderma viride, isolated from soil samples from the Kivu-region of Zaire, are antagonistic and mycoparasitic to four soil-borne Phytophthora spp. Radial growth of Phytophthora cinnamomi, Phytophthora cactorum, Phytophthora fragariae or Phytophthora nicotianae mycelia was inhibited in all antagonist-pathogen combinations; mycelial mats of Phytophthora colonies were overgrown by the antagonists and hyphae lysed. Samples of mycoparasited mycelium plated on benlate-amended PDA to inhibit the development of antagonists, showed severely reduced vitality after 77 days of dual culture.
