Leaf blight disease caused by pathogenic fungus Phytophthora infestans is the major disease in potato that can reduce its production up to 100%. The use of biological agent Trichoderma viride as an inducing potato resistance against leaf blight disease has been considered potential method. The purpose of this study was to evaluate the use of biological agent Trichoderma viride in inducing potato plant resistance. The parameters observed were the growth of the potato plant and leaf blight intensity. Experimental research with complete randomized design with 6 treatments was applied. The results showed that the application of Trichoderma viride could reduce the intensity of leaf blight disease and increase the growth of the potato plant. Trichoderma viride application could improve the systemic resistance of potato plants.
Key words: Trichoderma viride / leaf blight intensity / Phytophthora infestans
