Abstract

Phialospores of four isolates of Gliocladium virens viz., 15GV1, 26GV1, 1AGV2 and IAGV6 responded differentially to soil fungistasis in different soils of West Bengal according to the properties of soils explored. The pH of soil appeared to be the cardinal factor. The effect of soil fungistasis was more pronounced in alkaline soil followed by neutral soil but gradually decreased due to reduction of soil pH to acidic level. Fungistasis was more in unsterilized soil compared to sterilised one.
