摘要

辣椒（Capsicum annum var. grossum Sendt.）采集了出现白色至灰色不规则斑点的叶片。在马铃薯葡萄糖琼脂中分离并培养了病菌。通过接种该病菌的菌悬液，在辣椒幼苗上证明了其致病性。根据形态、培养和分子调查（ITS、gapdh 和 cmdA），确定病原体为 Stemphylium lycopersici。这是印度首次报道 Stemphylium lycopersici 引起辣椒叶斑病。

First report of Stemphylium lycopersici associated with leaf spot disease of Capsicum annum var. grossum Sendt. in India

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.

期刊介绍： Australasian Plant Disease Notes is an international journal for publication of short reports from all countries which describe original research that transcends national boundaries. All aspects of plant pathology are covered including new geographical records of diseases or pathogens, new pathogens or pathogen strains, taxonomic papers, quarantine notes, disease management and diagnostic methods. Australasian Plant Disease Notes is a publication of the Australasian Plant Pathology Society.
