During the year 2018–19, collar rot symptoms on Sugandh mantri plants were observed in fields in Agartala district of West Tripura state of India with a disease incidence of 20%. In the early stages of disease development, typical collar rot symptoms exhibited were dark brown necrotic lesions on the stem base. Later, the affected plants completely rotted and died. The diseased samples plated on PDA medium showed abundant, fluffy, dense white mycelia with reddish brown spherical sclerotia matching with the morphology of Sclerotium delphinii. The internal transcribed spacer (ITS) region of rDNA of the fungus was amplified and sequenced. The sequences revealed 99–100% identity with Sclerotium delphinii. The Koch's postulates were performed on three-month-old Sugandh mantri plants to confirm the pathogenicity of the isolated fungus. To the best of our knowledge, this is the first report of Sclerotium delphinii causing collar rot disease on Sugandh mantri plants in India.

2018-19 年期间，在印度西特里普拉邦 Agartala 地区的田间观察到 Sugandh mantri 植物的颈腐病症状，发病率为 20%。在病害发展的早期，典型的颈腐病症状表现为茎基部出现黑褐色坏死病斑。后来，受影响的植物完全腐烂并死亡。接种于PDA培养基上的患病样品显示丰富、蓬松、致密的白色菌丝体和红棕色球形菌核，与海豚菌核的形态相符。对真菌 rDNA 的内部转录间隔区 (ITS) 进行了扩增和测序。序列显示与海豚菌核有 99-100% 的同一性。对三个月大的 Sugandh mantri 植物进行了科赫假设，以确认分离出的真菌的致病性。据我们所知，这是第一次报道海豚菌核在印度的 Sugandh mantri 植物上引起颈腐病。
