Abstract:
Sclerotium rolfsii is a well-known soilborne fungus causes root rot, stem rot, collar rot, wilt and foot rot in several plants. The pathogen was exposed to various media, light conditions and temperatures in order to ascertain mycelial growth and the number of sclerotia of S. rolfsii. The results demonstrated that potato dextrose agar was the best solid media for S. rolfsii mycelial growth and sclerotia formation out of the six solid media evaluated. In the light experiment, alternate cycles of 13 hours light and 11 hours darkness resulted in the better mycelium growth as compared to the constant light and dark conditions. Among the different temperature six levels tested,the growth of S. rolfsii was maximum at 28 °C.
