Colonies of Trichoderma harzianum were inhibitory of strains of Fusarium culmorum in different environmental conditions. The degree of inhibition was dependent on the temperature and water activity treatments. Nearly all macroscopic analysis of the Petri plates revealed that Trichoderma harzianum against F. culmorum was a competitor for space and nutrients. In these conditions the microscopic study showed that Trichoderma harzianum was a mycoparasite. The possible production of cell-wall degrading enzymes by Trichoderma harzianum and its effect on mycelia of F. culmorum are discussed.
