Strychnos potatorum L.f., is a well-known medicinal plant found in peninsular India and Sri Lanka, which is widely used in traditional and modern medicines for curing various kinds of diseases. In January 2020, while conducting a foliar fungal disease investigation in Kerala, India, a leaf spot and blight disease was spotted on S. potatorum. The pathogen was isolated and identified as Curvularia verruculosa based on symptomatic studies, culture characteristics, conidial morphology, multigene (ITS-LSU-GAPDH-TEF1-α) molecular sequences analysis, and concatenate multigene (ITS-GAPDH-TEF1-α) phylogeny. Koch's postulates were evaluated in vitro, and similar symptoms and re-isolation of the pathogen confirmed the association of C. verruculosa with leaf spot and blight disease. To our knowledge, this is the first report of C. verruculosa causing foliar disease on S. potatorum in India.

马钱子是一种著名的药用植物，发现于印度半岛和斯里兰卡，广泛用于传统和现代药物中治疗各种疾病。2020年1月，在印度喀拉拉邦进行叶部真菌病害调查时，在马铃薯链球菌上发现叶斑病和枯萎病。根据症状研究、培养特征、分生孢子形态、多基因（ITS- LSU-GAPDH-TEF1-α）分子序列分析和串联多基因（ITS -GAPDH-TEF1-α）系统发育，分离并鉴定该病原体为疣状弯孢霉（Curvularia verruculosa）。科赫假设在体外进行了评估，相似的症状和病原体的重新分离证实了C. verruculosa与叶斑病和枯萎病的关联。据我们所知，这是首次报道C. verruculosa引起S. verruculosa 叶部病害。印度的马铃薯。
