| Abstract: | A new leaf disease on Chinese quince (Chaenomeles sinensis) was recently noted in Mount Maoshan, Jurong City, Jiangsu Province, China. Symptoms began with irregular lesions on tips or margins of the leaves, which gradually developed into concentric rings. The lesions eventually spread to cover one half or the entire leaf, leading to eventual desiccation and defoliation. Disease survey and responsible agent isolation was conducted in this study. Based on morphological characteristics, combined gene sequence analysis of ITS, G3PDH, HSP60 and RPB2, and Koch’s postulation, the causal agent of this new disease was identified as Botrytis cinerea. |
