Abstract:

The aim was to prevent anthracnose of Sargentodoxa cuneata in Qian Dongnan State of Guizhou Province. The pathogen was obtained by tissue isolation, and identified by separation, spores size determination and cultivation in this experiment. The microscopic examination method showed that the disease was caused by Colletotrichum sp., and the spores were 5.2-6.5 μm×13.0-33.8 μm through size determination. Based on host and pathogenic feature, the pathogen was Colletotrichum gloeosporioides. The disease of Sargentodoxa cuneata was caused by Colletotrichum gloeosporioides. in Qian Dongnan State of Guizhou Province, and the disease could be reduced through agricultural measures and chemical control.
