Abstract
: Fungal diseases are one of the major risks in chilli production. Plant diseases are being controlled commonly by the application of synthetic fungicides. Trichoderma species found to be most effective antagonism of foliar and soil borne pathogens. In the present study, dual culture assay was conducted against phytopathogenic fungi of chilli in vitro and examined percent inhibition by the potential biocontrol agent. Dual culture plate test revealed that the percentage growth inhibition of Colletotrichum gleosporoides, Fusarium oxysporum, Pythium apanidermatum, Curvularia lunata and Alternaria sp by Trichoderma asperellum were in the range of 26.4 to 83.5 %.T. asperellum, a less studied fungus, is also a successful biological control agent against a wide range of plant pathogens. Thus, the aim of this research is to assess the antagonistic ability of T. asperellum towards chilli phytopathogenic fungi under in vitro conditions. The antagonistic efficacy of T. asperellum can be exploited in the disease management of chilli in field conditions.
