Abstract
In vitro bioassays were carried out to evaluate the antagonistic potential of Trichoderma harzianum Rifai against Fusarium solani, individually as well as in combination with aqueous leaf extracts of Terminalia arjuna (Roxb.) W. & A., Mangifera indica L. and Azadirchta indica (L.) A. Juss. T. harzianum exhibited significant antifungal activity against F. solani resulting in a significant reduction of 70% in radial growth. Among the three test plant species, aqueous extract of T. aurjuna showed the maximum antifungal activity resulting in 74% reduction in colony diameter of F. solani followed by M. indica that induced 67% decline. Lowest affectivity i.e. 54% was observed in case of A. indica. Any of the three test plant species failed to enhance the efficacy of the T. harzianum in suppressing the mycelia growth of F. solani as compared to its individual competence.
