Abstract

Antagonistic effect of the fungus Trichoderma asperellum to the pathogenic fungus Phytophthora parasitica var. nicotianae in vitro and in vivo was investigated in this paper. Trichoderma asperellum, grown on nutrient medium in dual culture with pathogenic fungus Phytophthora parasitica var. nicotianae inhibits the growth of the pathogen and continues to develop on its colony. Development of the fungus grown in presence of the antagonist was reduced by 32.14%, and the percentage of inhibition was 67.86%. T. asperellum - biological agent for control of the soil-borne pathogen P. parasitica var. nicotianae, was investigated on tobacco seedlings in a protected area. Seedlings were inoculated both with pure culture of the pathogen and with dual culture grown in presence of the antagonist. In the seedlings treated with culture of the pathogen high percentage of infection was observed, while the seedlings treated with dual culture developed healthier and better.
