摘要

Capsicum (Capsicum annum var. grossum Sendt.) is a popular and widely cultivated vegetable crop. The leaves showing white to grey irregular spots were collected. The organism was isolated and cultured on potato dextrose agar from the diseased samples. The pathogenicity was proved on capsicum seedlings by inoculating hyphal suspension of the organism and koch’s postulates were proved by re-isolating the pathogen. The pathogen was identified as Stemphylium lycopersici based on morphological, cultural and molecular investigation (ITS, gapdh and cmdA). This is the first report of Stemphylium lycopersici causing leaf spot of capsicum in India.
