Abstract:Phytophthora capsici is a important pathogen to sweet pepper in Shan-ghai Suburbs. It produces a lot of sporangia, shuttlelike, ellipsoidal, oncarrot agar or in water. It has resistans to malachite green, when theconcentration of malachite green in PDA is 1 ppm it begins to grow. Itcan not only utilize nitratenitrogen as the only nitrogen source, but alsostarch as the only carbon source. It produces visible brown coloration inthe medium which containscasein hydrolysate-tyrosine. Its maximum growthtemperation is between 34-37℃.
Keywords:sweet pepper  phytophthora capsici  morphology  physiology
