Trichoderma is well known for its antifungal and antibacterial activities. This microorganism is having application in agriculture as biofertilizer and biopesticide. During its growth it competes with the plant pathogen for the nutrients and other growth factors, during this process it can inhibit the growth of pathogens thus help in plant protection. Tomato is grown widely in Rayalaseema region, Andhra Pradesh, India. It is economically important crop grown during almost all seasons by local farmers. Tomato crop get infected with various bacteria and fungi resulting in crop loss. Our study was aimed to isolate fungi infecting the tomato crop and evaluate the antimicrobial activity of Trichoderma. Three different fungi were isolated from infected tomato plant leaves. The isolated fungi were tested for their susceptibility with bio control agent Trichoderma. It was able to inhibit the growth of tested fungi.
