Curvularia lunata is a fungal pathogen that causes leaf spot, leaf blight and root rot diseases in plants, and sinusitis, mycotic keratitis, asthma and conjunctivitis in human. This in vitro study was conducted to assess the potential of three synthetic fungicides to control C. linata. The fungicides evaluated in this study were thiophenate methyl 70% WP, metalaxyl+mencozeb 72% WP and fosetyl-Al 80% WP. The concentrations of these fungicides used in food poisoning technique were 50, 100, 150, 200 and 250 ppm, which were compared with a control having 0 ppm concentration. Metalaxyl+mencozeb proved the best fungicide in inhibiting the fungal growth by 26–67% over control. Thiophenate methyl and fosetyl-Al showed poor activity against the targeted pathogen by suppressing its radial growth by just 15–26% and 8–12%, respectively.
