Corm rot is an important disease of Gladiolus caused by a soil-borne fungal pathogen Fusarium 0xysporum f.sp. gladioli (Massey) Snyd & Hans. The present study was carried out to investigate the effect of inoculum density of F. oxysporum f.sp. gladioli on incidence and severity of disease, plant mortality and subsequent effect on plant growth of gladiolus (Gladiolus grandiflorus sect. Blandus) cv. Aarti. Treatments included a control and 2, 4 and 8 g chickpea carried fungal inoculum per 100 g of soil. Disease incidence of 100% was recorded in 4% treatment. However, highest wilt incidence (20%), mortality (20%), disease severity (rating scale 2-3) and number of infection lesions on corms were recorded in 8% treatment. Both root and shoot growth significantly declined in all the inoculated treatments as compared to control.
