We measured the toxicity of nine fungicides on Phomopsis vexans by using the mycelium growth rate method. The results showed that all the nine fungicides could inhibit the growth of P. vexans, among them, 25% prochloraz emulsifiable concentrate (EC) had the strongest fungistasis, with the EC50 value of 0.025 2 mg/L, while 20%thiazole zinc suspension concentrate (SC) had the weakest fungistasis, with the EC50 value of 63.933 9 mg/L. Among the rest seven fungicides, the inhibition effect decreased successively as follows:30%difenoconazole·propiconazol SC, 70%thiophanate-methyl wettable powder (WP), 30% difenoconazole·azoxystrobin SC, 25% propiconazol EC, 70% propineb·thiophanate-methyl WP, 40%difenoconazole SC, 80%thiram·ziram WP.
