Abstract: Fusarium wilt has become a serious problem in recent years in all chilli growing irrigated tracts of India. Wilt of chilli (Capsicum annuum) caused by Fusarium oxysporum f.sp. capsici. In present investigation bio-agents, botanicals and fungicide were evaluated in-vitro and in vivo condition against Fusarium oxysporum. Among all the treatments Trichoderma viride was found most effective in inhibiting (80.87%) of mycelial growth of Fusarium oxysporum f.sp. capsici followed by Pseudomonas fluorescens (78.00%), T. harzianum (76.08%), neem leaf extract @ 10% (53.11%) and jatropha leaf extract @ 10% (33.50%) as compared to treated check carbendazim 50 WP (91.87%) and untreated check (0%) under in vitro laboratory condition. A total of seven treatments, replicated three times were taken up in randomized block design. All treatments were significantly increased plant height, root length, fresh and dry shoot-root weight and yield per plant. Among all the treatments the minimum wilt incidence was recorded in treatment T1- carbendazim 50 WP seed treatment (ST) (8.33%), followed by T3 – Trichoderma viride (ST) (13.88%), T2- T. harzinum (ST) (19.44%), T4- P. fluerscence (ST) (16.66%), T5- Neem leaf extract (ST) @ 10% (25.00%), T6- Jatropha leaf extract (ST) @ 10% (33.33%) and maximum percent disease incidence was found in T0- control (44.44%).
