Abstract

Phytophthora blight, caused by Phytophthora capsici, is a devastating disease threatening the bell pepper industry. This pathogen affects all parts of plants including causing rot, blight, significant harm and losses the Capsicum species. In the present study, symptoms of blight and damping off were noted during two years of field surveys, February–November 2021–2022. Seventy-two isolates were obtained from rhizosphere soil samples of the infected bell pepper (Capsicum annuum) plants. Phytophthora capsici Leonian was identified on the basis of morphological and cultural characteristics and culture being deposited in the Indian Type Culture Collection (ITCC) in New Delhi. The 18S rRNA ITS region was undertaken to confirm species identity. A phylogenetic tree confirmed that the obtained ITS region sequences were identical to Phytophthora capsici isolates. This is the first report of Phytophthora blight on bell peppers from the Haryana region of India.

引起印度哈里亚纳邦甜椒疫霉疫病的辣椒疫霉首次报道

辣椒疫霉（Phytophthora疫病）是一种威胁辣椒产业的毁灭性病害。这种病原菌影响植物的所有部位，包括引起腐烂，枯萎，严重危害和损失辣椒物种。在本研究中，在2021-2022年2月至11月的两年实地调查期间，发现了枯萎病和枯萎的症状。从侵染辣椒植株根际土壤样品中分离得到72株菌株。根据新德里印度模式文化收藏（ITCC）的形态和文化特征鉴定了辣椒疫霉（Phytophthora capsici Leonian）。采用18S rRNA ITS区进行物种鉴定。系统发育树分析证实，所获得的ITS区序列与辣椒疫霉菌分离株完全相同。这是印度哈里亚纳邦地区甜椒疫霉病的首次报道。
