Toxicity and apply of 13 kinds of fungicides on Curuularia lunata

The toxicity of 13 kinds of fungicides on Curuularia lunata, like Tilt, Score, Celest, Amistar, Aomeiling, and so on, were measured by the method of growth ratio. Their regressive equations and EC_(50) were calculated. The results demonstrated that there were 4 kinds of fungicides, such as Score, Topsin-m,Ridomil and Aomeiling3, which could inhibit C. lunata very effectively; The toxicities of Celest, Tilt, AF-136, AF-137 and Amistar had also highly inhbitant, but they had less effect than the former 4 fungicides; The effects of Aomeiling2, Aomeiling1, 2116 and Aomeiling4 on C. lunata were not significant. The experimental results would be useful to the further studies on the selection of effective fungicides and the optimal mixture of fungicides on Curuularia lunata.
