Abstract:

Studies on the varied physiological requirements of Sarocladium oryzae, which causes sheath rot of rice, were undertaken in the Department of Plant Pathology of the Annamalai University, Chidambaram. It was revealed that Potato dextrose agar medium,Czapeks Dox agar medium and Carrot agar mediumsupported significantly maximal radial growth (83.50mm, 78.50mm and 77.00mm, respectively) and with bio-mass production (774.09 mg; 734.87 mg and 710.89mg, respectively). Significantly, exposure of pathogen to acidic pH (4.0) recorded maximum mycelial growth (82.68 mm), mycelial dry weight (767.00 mg) which was followed by exposing the pathogen to pH 4.5 under in vitro.The highest radial growth of 66.10mm in 12 hr light and 12 hr darkness closely followed by 8 hr light and 16 hr darkness (59.50mm). The least mycelial growth was observed under exposing sunlight for 4 h (3.70 mm). S. oryzae experienced its greatest radial growth at 30°C was found to be more conducive for the mycelial growth of S. oryzae (73.00 mm) under in vitro recording the highest mycelial dry weight of 764.704 mg, which was followed by 35°C.
