Abstract: The serious fungi disease of Radix pseudostellariae annually occur in Guizhou Qiandongnan from March to May. The main pathogen was Rhizoctonia solani which was obtained by field investigation, tissue isolation and microscopic identification. It could cause the damping- off disease of Radix pseudostellariae. Alternaria alternate was found in disease soil which had pathogenic ability to seedlings of Radix pseudostellariae. The results of primary bio- control study showed that GH18 strain of Bacillus spp. had significant effect on Rhizoctonia solani and Alternaria alternate, respectively.
