First report of leaf spot of hyacinth bean caused by Corynespora cassiicola in Sichuan, China
Plant Disease 100 (6), 1235-1235
Abstract: During 2014, hyacinth beans (Lablab purpureus) grown in Sichuan Province, China were observed with symptoms of red-brown, circular to irregular leaf spots on leaves which became ivory or dark brown with concentric rings. On pods, spots were irregular. The disease resulted in premature defoliation and pod rotting. The fungus Corynespora cassiicola was isolated from the diseased plants. The identification was based on morphological characteristics and DNA sequence analysis. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
