Effect of Nutrients on Biomass Production of Helminthosporium Tetramera A Leaf Spot Pathogen of Sugarcane (Saccharum Officinarum)

Abstract : Helminthosporium tetramera was a pathogen of Saccharum Officinarum, isolated from diseased leaves Nashik district and used for the present study. Pathogen grown on Czapek-Dox liquid medium substituting or adding different carbon, nitrogen to study biomass production. The growth as dry mycelial observed 8th day incubation period. A grate extent variation nitrogen. Among carbon source, fructose shows maximum while glucose with minimum biomass. From source cobalt nitrate barium control condition recorded.
