| 摘 要： | Isolate PD1 of Phytophthora was isolated from diseased black pericarp wax gourd in Guangxi in 2005. The morphological and biological characters of the isolate were examined, and its sequence of ribosomal DNA-ITS was analyzed. The range of growth temperature of the isolate was 10-37℃ and the optimal one was 31℃. The pathogen was sensitive to 10 mg/kg of malachite green, and its ability for starch utilization was weak. A wide host range of the pathogen was confirmed by artificial inoculation. The sizes of sporangia were (37.5-71.7) μm×(20.8-47.5) μm (av. 55.0 μm×30.4 μm). Microcycle conidiation of the pathogen was observed. The pathogen was identified as Phytophthora drechsleri Tucker based on its morphological and biological characters as well as ribosomal DNA-ITS sequence.
