| Abstract: | By the mycelium growth rate methods, the toxicities of five fungicides to Fusarium osyspontm f. sp. niveum and Fusarium osysporum f. sp. Cucumerinum were tested. The results showed that carbendazim and flusilazole had the best toxicity against Fusarium osysporum f. sp. niveum and the ECho were 2.6280 mg/L and 3.3268 mg/L, respectively. Carbendazim and difenoconazole had the best toxicity against Fusarium osysporum f. sp. Cucumerinum and the EC50 owere 0.6660 mg/L and 1.9343 mg/L, respectively. In addition, two fungi were highly sensitive to carbendazim and flusilazole. |
