摘要：
Cassava (Manihot esculenta) plants were observed in the Amazon region showing extensive leaf blight. The identity of the pathogen was confirmed based on morphological characteristics and the sequence of ITS region of the rDNA. Koch's postulates were fulfilled and pathogenicity was demonstrated. Cassava leaf blight, caused by Rhizoctonia solani AG-1 IA, is reported for the fast time in Brazil.
