The bio-agents viz. Trichoderma viride, T. harzianum, Pseudomonas fluorescens, plant extracts viz. neem oil @ 10% and neem seed kernel extract @ 10% and Neen leaf extract @ 10% against F. oxisporum under In vitro experiment was analyzed by using CRD with six treatments and three replication viz. Trichoderma viride, T. harzianum, Pseudomonas fluorescens, Neem leaf extract, neem oil, and neem seed kernel extract. Observations recorded at 24, 48, 72, 96, 120, 144 and 168 hrs., respectively. T. viride was inoculated directly in PDA poured plate in a dual culture technique which gave the best results among all the treatments (1.475) followed by Trichoderma harzianum (1.765). Whereas in case of neem products neem oil @ 10% was best effective (5.450) followed by neem leaf extract (6.375) followed by NSKE (6.625). It was seen that all the treatments were significant over control (8.285).
