Abstract:

This paper is about the preliminary research on anthracnose of Holboellio latifolia wall in kaili college botanical gardens, and briefly puts forward its prevention about this disease. The pathogen can be gained 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 12.5-20 μm×3.75-7.5 μm through size determination. Based on host and pathogenic feature, the disease of Holboellio latifolia wall is caused by Colletotrichum gloeosporioides in kaili college botanical gardens, we can reduce the disease through agricultural measures and chemical control.
