Antagonistic bio-control potentiality of Trichoderma harzianum in controlling the growth of Fusarium solani and Sclerotium rolfsii under in-vitro conditions

Abstract

In this study, antagonistic bio-control potentiality of Trichoderma harzianum on the growth damping-off pathogens Fusarium solani and Sclerotium rolfsii was evaluated under in- vitro condition on Potato Dextrose Agar (PDA) medium. Results showed the growth inhibition of Fusarium solani and Sclerotium rolfsii to the extent of 77.8% and 66.7%, respectively in comparison with solo culture plate of test pathogen which exhibited 0% inhibition. Thus Trichoderma harzianum can be a best tool for the biological control of test pathogens.
