During the Kharif seasons of 2023–24 and 2024–25, leaf blight and stem rot symptoms were observed on mungbean (Vigna radiata) at Research Farm, ICAR-IIPR, Kanpur, India. Symptoms began as water-soaked lesions on leaf margins and stunted growth, progressing to necrotic stem and pod lesions. The causal pathogen was identified as Pythium catenulatum based on symptomatology, pathogenicity, and ITS-based molecular analysis. This is the first report of P. catenulatum causing stem rot in mungbean in India.
