Two pathogens were isolated from root rot of kiwifruit in Heping county, Guangdong Province. According to their cultural characters and morphology, they were identified as Phytophthora cinnamomi Rands ( mating type A1 )and Fusarium solani (Mart.) Sacc.. By artificial inoculation in greenhouse, it was showed that P.cinnamomi possessed higher pathogenicity, and F.solani was the second invader which could not attack the kiwifruit alone, but might accelerate the root rot together with P.cinnamomi.
