Antagonistic Potential of Endophytic Chaetomium Against Phytophthora infestans (Mont.) De Bary Causing Late Blight Disease on Potato Srinivasan. V.M., Krishnamoorthy A.S. Department of Plant Pathology, Tamil Nadu Agricultural University, Coimbatore-3, Tamil Nadu, India Online published on 2 January, 2017. Abstract The present research was carried out to study the diversity of endophytic fungi from the solanaceous plants such as Solanum tuberosum, Capsicum annum, Nicotiana tabacum, Solanum lycopersicum, Solanum melongena, Solanum torvum, Solanum nigrum, Datura alba, Solanum trilobatum, Solanum surattense and investigate their antagonistic potency against Phytophthora infestans causing late blight disease on potato. Abundance of each fungal species from leave samples was determined by calculating frequency of isolation. The fungal endophytes viz., Alternaria, Aspergillus, Fusarium, Colletotrichum, Chaetomium, Nigrospora, Penicillium, were isolated from the solanaceous plants. Among the endophytes isolated Chaetomium was most predominant. Totally four chaetomium isolates were obtained and their antagonistic activity were tested against Phytophthora infestans causing late blight disease on potato. The Chaetomium isolate Ch-1 was found to be more effective than other three isolates which was recorded 60.67 percent inhibition over control.
