Efficacy of different isolates of Trichoderma against early blight of tomato
A Ramakrishna, S Desai, G Uma Devi and T Uma Maheswari
(Ellis and Martin) is a pathogen causing early blight of tomato resulting in heavy yield losses. Thirteen isolates of Trichoderma tested against Alternaria solani
and considered for assessment of variation as well as for management. Out of 13 Trichoderma isolates tested, T4 exhibited maximum inhibition (66.72%) against A. solani
followed by T6 (65.57%). The isolates varied in their antagonistic ability against A. solani
. While, T4 and T6 showed >65% inhibition, all remaining isolates exhibited >50% antagonism showing their potential as biocotnrol agents.
