Abstract
Effect of light and pH on mycelial growth and sporangium formation of Phytophthora capsici Leon, causal fungus of fruit rot of red pepper was carried out on culture media. The maximum mycelial growth occurred at and pH 6.0 on potato sucrose agar. The fungus did not produce sporangia readily in dark condition. However, abundant sporulation occurred by illuminating continuous cool white fluorescent light with 2000 lux for 48 hrs. at . Oat meal agar was one of the best media for sporangia formation.
