Lentil (Lens culinaris Medik) is an important crop for farming systems in India, the major states producing lentil are Madhya Pradesh, Uttar Pradesh, Bihar and Punjab. It is one of the most important and nutritious Rabi pulse crop. The lentil crop is mostly affected by various fungal diseases e.g. vascular wilt (Fusarium oxysporum f.sp. lentis), Sclerotinia stem rot (Sclerotinia sclerotiorum) and collar rot (Sclerotium rolfsii Sacc.), in which vascular wilt is most destructive soil borne diseases of lentil growing area worldwide. In the present investigation the eight commercially available fungicides were tested in vitro for their efficacy in inhibiting the growth of the pathogen and evaluated the antagonistic efficacy of potent bio- control agents against Fusarium oxysporoum f.sp. lentis. It was observed that the 100 per cent inhibition of mycelial growth of pathogen was found in the treatment with Carbendazim 50 %WP, Cymoxanil 8%+ Mancozeb 64%, Tebuconazole 25.9% EC and Propiconazole 25% EC at all three concentrations (50ppm, 75ppm and 100ppm). The least inhibition per cent of mycelial growth was recorded (50.00%, 54.17% and 60.42%) in Mancozeb 75 % WP at all three concentrations (50ppm, 75ppm and 100 ppm) after 144 hrs. incubation. In the tested bio-agents, the maximum mycelial growth inhibition was recorded by Trichoderma viride (76.25 %)) which was significantly superior from all the tested bio-agents followed by Chaetomium globosum (75.00%) and Pseudomonas fluorescens (71.25%). The minimum mycelial growth inhibition was recorded by Bacillus subtilis (55.00%) followed by Trichoderma harzianum (68.75%) at 144 hours.
