| Abstract: | Cassia corymbosa is an introduced ornamental shrub in the Yangtze River Delta area. Severe powdery mildew occurred on C. corymbosa from late August to mid-November. It caused early defoliation and some infected plants failed to survive in the following year. The powdery mildew is caused by Oidium cassiae-siameae. The pathogen did not develop teleomorph under field observation in the last three years. This is the first report of C. corymbosa, as a new host of powdery mildew caused by Oidium cassiae-siameae. This fungus is a newly reported species in mainland China. |
