Abstract

Fungi of the genus Trichoderma are widely used in production of biological products which show high efficiency in the control of many soilborne pathogens. Laboratory tests with Trichoderma asperellum grown together with the pathogenic fungus Rhizoctonia solani as dual culture showed high inhibitory effect of this antagonist on the pathogenic fungi. It represses the growth of the pathogen and develops on its colony. The growth of pathogenic fungus grown in the presence of antagonist was reduced by 36.74%, with percentage of inhibition being 63.26%. Biological agent T. asperellum was tested for control of R. solani on tobacco seedlings in protected conditions. Tobacco seedlings were inoculated both with pure culture of the pathogen and with dual culture, where the pathogen was grown in the presence of the antagonist. Seedlings treated with dual culture were healthier and had a more rapid growth, while those treated with pure culture showed high percentage of infestation.
