The isolate Rhizoctonia solani AG-1 IB collected from the diseased leaves of soybean were identified by the method of internal transcribed spacer sequence analysis. In this study, we focus on the biological characteristics and infection process of AG-1IB. Morphological, nucleus, chromosome, and infection process were observed. Typical infectious structures as infection cushion and appressorium were observed during the infection process.
