| Abstract: | Mango anthracnose is one of the most serious diseases on mango. In this study, the sensitivity of Colletotrichum spp. collected from different mango production areas to difenoconazole was determined with mycelium growth rate method. The result showed that the mean EC50 value of 136 isolates was (1.46±0.14) mg/L, and the minimum and maximum EC50 values were 0.09 mg/L and 9.74 mg/L, respectively. The sensitivity frequency was not normally distributed. There was no significant difference in mean EC50 values among Colletotrichum spp. from different regions. The mean EC50 value of strains isolated from Guizhou was the highest, while that from Hainan was the lowest. The tested isolates contained 13 species, of which C. cordylinicola had the lowest mean EC50 value, and C. gloeosporioides had the highest mean EC50 value. |
