ABSTRACT
Blight of Colocasia (Colocasia esculanta L.) is caused by phytophthora colocasiae. This paper
describes the efficacy of Trichoderma spp against sensitive and resistant isolates of Phytophthora
colocasiae by dual culture method under in laboratory conditions. Trichoderma viride T. harzianum,
T. virens, T. koningii and T. pseudokoningii species were used for antagonistic study. Results
indicated that all Trichoderma species showed antagonistic combat, but among them, T. viride and
T. harzianum showed 77.77% antagonism than others. The inhibition percentage of Trichoderma
viride and T. harzianum was considerably affected and differed significantly (p<0.05). Resistant
isolate of pathogen was restricting the antagonism in some degree.
Keywords: Colocasia esculanta, Phytophthora colocasiae, Trichoderma species dual culture.
