Evaluation of antagonistic activity of potential soil fungi against pathogen
Vasantha Kumari MS, Latha V
The mycoflora were isolated by using soil dilution technique and soil plate technique on Potato Dextrose Agar medium supplemented by suitable antibiotics i.e streptomycin. Identification and characterization of the mycoflora were made with the help of authentic manuals of fungi. This particular study examined distribution and relative abundance of earthworms under different land use patterns and their influence on the physico-chemical properties of the soil. We measured the species composition communities across the ecosystems and effect of abiotic factors on them from various ecological regions of southern India. A simple dual culture agar plating technique has been developed and evaluated for its efficiency in determining the relationship of gut bacteria of sand fly with Leishmania donovani promastigotes. There are about fouteen morphologically distinct fungal colonies have been isolated from the gut homogenate of Phlebotomus argentipes. In dual culture method, each fungi isolate was inoculated in one half of the plate and the promastigotes of Leishmania was inculcated in the other half by poured. After incubation, the type of association was determined based on the presence or absence of promastigotes colonies. The efficient antagonistic fungi, also possessed in vitro multiple traits for plant growth promotion and improved rice seedling growth.
