Abstract: Leaf blight of tomato caused by a complex mycoflora viz., Alternaria solani, Fusarium oxysporum and Curvularia lunata. The disease complex causes considerable yield as well as post-harvest losses. In vitro screening of nine different contact, systemic and combi-products against three fungal pathogens was done employing poison food technique. Cent percent radial growth inhibition of A. solani and F. oxysporum was found in case of Carboxin + Thiram 0.2%, Hexaconazole 0.1% and Carbendazim + Mancozeb 0.2%. Propineb 0.2% recorded least percentage inhibition (49.66%) among all the chemicals against Alternaria solani and Fusarium oxysporum. Carbendazim 0.15%, Difenoconazole 1.5%, Carboxin + Thiram 0.2% recorded 100% growth inhibition of Curvularia lunata, While Thiophanate methyl 0.1% was least effective only reducing 45.76% growth of the C. lunata. The study will be helpful for further investigation and selection for best Agro chemicals for management of fungal leaf blight of tomato.
