Summary Shisham ( D albergia sissoo ) is an important multipurpose tree with great economic importance, but this tree has been devastated by dieback disease. Seedlings and asexually propagated (cuttings) plants were artificially inoculated with four fungi ( F usarium solani , B otryodiplodia theobromae , C urvularia lunata and G anoderma lucidum ) to evaluate the potential role of these fungi in shisham dieback disease. Results at 2 years revealed that highest disease was caused by inoculation of F . solani (31.39%), followed by B . theobromae (19.042%) and C . lunata (12.22%), but no dieback disease was caused by G . lucidum . During both years, seedlings exhibited greater susceptibility to disease (17.24%) compared to cuttings (7.83%). In particular, F . solani caused more disease in seedlings (46.18%) compared to cuttings (16.61%). With the F . solani inoculations, maximum disease rate was observed at 8 weeks post‐inoculation both in seedlings (77%) and in cuttings (31%), but the maximum disease increase was observed at 4–5 weeks post‐inoculation. Analysis of variance showed significant differences among the different fungi and also between seedlings and cuttings. F . solani can be considered as a major fungal pathogen contributing to dieback disease of shisham, and asexual propagation can reduce the severity of dieback.
