Abstract
The population dynamics of fungi in banana field soil, antibiotic potentiality of
the soil fungi and antifungal ability of some plant extracts against Fusarium solani was studied.
Maximum number of colonies were isolated during the month of November. The genus
Aspergillus, Pencillium, Trichoderma, and Fusarium were isolated most frequently. Antibiotic
interaction of the soil fungi against F.solani was performed. The test pathogen varied in its
sensitivity to the metabolic growth products of antagonistic fungi. The maximum percentage of
inhibition of pathogen was 85% against T.viride and 75% of inhibition was against A.niger.
Culture filtrate of the soil fungi and the suppression of F.solani was observed. The maximum
percentage of suppression of pathogen was observed against T.viride and A.niger at 20 per cent
concentration level. The leaves of medicinal plant extract such as Adathoda vasica,
Azadirachta indica and Vitex negundo was more effective at 20% concentration against the
pathogen was reported. The leaf extracts (Adathoda vasica, Azadirachta indica and Vitex
negundo) with culture filtrate of Trichoderma viride in combination of 1:1 ratio was more
effective at 20 per cent level against the F.solani. However, the combined treatment of A.vasica
and T.viride was more effective in controlling the pathogen F.solani causing wilt disease of
banana.
