White spongy ischolar_main-rot of Paulownia fortunei was observed in plantations raised at New Forest trial plantation and Doiwala Social Forestry plantation, Dehra Dun. Affected trees showed die-back symptom besides white cottony mycelium on bark of diseased ischolar_mains. The causal organism was identified as Heteroporus biennis (Bull. ex Fries) Bull. Pathogenicity test established the relationship of the ischolar_main-rot fungus with the disease. Field assessment of the ischolar_main-rot was also carried out in the plantation at New Forest, Forest Research Institute, Dehra Dun.
