In vitro evaluation of antimicrobial bio-efficacy of different four organic formulations viz., Neem oil (@ 0.5, 1.0, 1.5% con.), Azadirachtin (@ 0.10, 0.15, 0.20% con.), Bijamrut (@ 5, 10, 15% con.) and Jivamrut (@ 5, 10, 15% con.) were evaluated at different three concentrations against Fusarium oxysporum f.sp. radicis-cucumerinum causing root and stem rot disease of cucumber. Among the four different organic formulations, Azadirachtin was found most effective by showing minimum mycelial growth of 47.48, 31.63 and 21.70 mm and 47.25, 64.86 and 75.89% per cent growth inhibition at 0.10, 0.15 and 0.20% concentrations respectively. The Jivamrut depicted highest mycelial growth 63.88, 55.83, 43.95 mm with 29.03, 37.97 and 51.17% lowest per cent growth inhibition of the pathogen at 5, 10 and 15% concentrations, respectively.
