Abstract :Interactions between Trichoderma harzianum strains and some soilborne plant pathogens insert ignore into journalissuearticles values(Gaeumannomyces graminis var. tritici, Fusarium culmorum and F. moniliforme); were studied on PDA medium. All T. harzianum strains tested produced a metabolite that inhibited growth of plant pathogenic fungi on PDA medium. When grown in liquid cultures containing laminarin, chitin or fungal cell walls as sole carbon sources, 2 strains of T. harzianum produced 1,3-b-glucanase and chitinase in the medium. Higher levels of these enzymes were induced by T. harzianum T15.
