Abstract

To investigate the antagonistic potentiality of Trichoderma harzianum against Fusarium oxysporum, Bipolaris sorokiniana and Sclerotium rolfsii.Dual culture technique was followed to evaluate the effect of antagonist.The inhibition percentage of Trichoderma harzianum was substantially affected and differed significantly (p<0.01).In case of antagonist the highest percent inhibition of Trichoderma harzianum was found 89.20% against Bipolaris sorokiniana followed by 88.69% in Fusarium oxysporum but statistically dissimilar with Sclerotium rolfsii 76.76%.In every case inhibition was more than 75%.
