Abstract [Objective] In order to control Curvularia Leaf Blight on Curcuma wenyujin. [Method] Five fungicides were used to screen by mycelia growth rate method and inhibition zone method. [Result] The results showed that the effect of 80% Mancozeb WP was the best to Curvularia clavata， 50% prochlorazmanganese chloride complex WP was lower. However， WG 50% carbendazim， 75% chlorothalonil WP and 70% thiophanatemethyl WP have no effect on the pathogen of Curvularia Leaf Blight. [Conclusion] 80% Mancozeb WP and 50% prochlorazmanganese chloride complex WP had obvious inhibitory effect on the pathogen of Curvularia Leaf Blight.
