Abstract: Tomato (Lycopersicon esculentum Mill.) is one of the most important vegetable crops grown all over the world. It is world’s 3rd largest vegetable crop after potato and sweet potato which is highly threatened by the Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici causing considerable economic losses in India as well as in the world. Six fungicides belonging to different groups and at different concentrations viz. 0.05%, 0.1%, 0.15% & 0.2% were screened, against the pathogen under in vitro condition to find out their relative efficacy in inhibiting the growth of the pathogen among which Benfil (Carbendazim 50% WP) was found effective at 0.1% concentration which inhibited the mycelial growth upto 92.5% as compared to control, followed by Matco (Metalaxyl (8%) + Mancozeb (74%). 72%WP) at 0.2% concentration with an inhibition of 84.64% and Blitox-50 (Copper oxy chloride 50%WP) at 0.2% with an inhibition of 83.92% over control. Fungicides like Manfil (Mancozeb 75% WG) and Daconil (Chlorothalonil) were found moderately effective. Among the treatments Srilaxyl (Metalaxyl 35% WS) was found least effective in inhibiting the mycelial growth of pathogen.
