A total of 196 isolates of Colletotrichum were obtained from leaves, stolons, and crowns of strawberry plants with anthracnose symptoms in eastern China, and were characterized based on morphology, ITS, and TUB2 gene sequences. All 196 isolates were identified as C. gloeosporioides species complex. 62 strains were chosen for further identification to the species level via phylogenetic analyses of multi-locus sequences of ITS, GAPDH, ACT, ApMAT, CAL, and TUB2. Three species from the C. gloeosporioides species complex were identified: C. siamense, C. fructicola, and C. aenigma. Isolates of C. siamense were tolerant to high temperatures, with a significantly larger colony diameter than the other two species when grown at temperatures above 36℃. Inoculation of strawberry plants confirmed the pathogenicity of all three species. Isolates of C. siamense resulted in the highest disease severity. The in vitro sensitivity of C. siamense and C. fructicola isolates to azoxystrobin and three DMI fungicides (difenoconazole, tebuconazole, and prochloraz) was determined. Both the species were sensitive to prochloraz, tebuconazole, and difenoconazole, but not to azoxystrobin. C. siamense isolates were more sensitive to prochloraz (mean EC50 values of 0.122) than C. fructicola isolates (mean EC50 values of 0.140) (P<0.05). C. fructicola isolates were more sensitive to difenoconazole and tebuconazole (mean EC50 values of 0.003 and 6.305, respectively) than C. siamense isolates (mean EC50 values of 0.056 and 8.885, respectively) (P<0.05). The present study provides valuable information for effective management of strawberry anthracnose.} }
