摘要
2021 年 2 月,巴西巴伊亚州 Vitória da Conquista 市普遍发生芫荽(Coriandrum sativum L.)的枯萎病和根颈腐烂病。从受害秧苗的根部和领部分离出一种卵菌,该卵菌在接种的秧苗上也会引起同样的症状。根据形态特征以及 ITS 和 cox2 区域的 DNA 序列,确定病原体为 Pythium aphanidermatum。据我们所知,这是巴西首次报道在芫荽植株上出现 P. aphanidermatum。
First report of Pythium aphanidermatum causing damping off, collar and root rot of coriander in Brazil
In February 2021, damping off and collar and root rot on coriander (Coriandrum sativum L.) became widespread in the municipality of Vitória da Conquista, Bahia, Brazil. An oomycete was isolated from root and collar segments of affected seedlings and caused the same symptoms in inoculated seedlings. Based on morphological features and DNA sequences from the ITS and cox2 region, the pathogen was identified as Pythium aphanidermatum. To the best of our knowledge, this is the first report of the occurrence of P. aphanidermatum on coriander plants in Brazil.
