The relative susceptibility of 19 strawberry cultivars (Fragaria × ananassa) to Colletotrichum fragariae was evaluated. F. virginiana and Potentilla canadensis were susceptible to C. fragariae; however, Duchesnea indica did not become infected after repeated inoculations. The fungus spread 450 m from an inoculum source to infect healthy strawberry plants.
