Disease incidence of radish yellows caused by Fusarium oxysporum f. sp. raphani Kend et Snyder. , was influenced by change of temperature. In our experiments, we found that the optimum temperature for disease development was 25±3℃, and the disease severity was significantly decreased by lower or higher of temperature. The pathogens grow on Czapek's agar at 8-36℃, with optimum at 20-28℃. It was found that survival of the pathogen in soil gave longer period in lower temperature than higher temperature. The optimum temperature (28℃) for germination of conidia and chlamydospore was hardly any different in soil or on water agar, except 24℃ was better for germination of chlamydospore on agar, but 28℃ still was best for germ tube development.
