What is the primary host range for strawberry anthracnose?

The primary host range for strawberry anthracnose is indeed strawberries and raspberries. This fungal disease, caused primarily by the pathogen Colletotrichum species, specifically targets these crops, leading to characteristic symptoms such as dark, sunken lesions on the fruit and foliage.

The specificity of this pathogen to strawberries and raspberries highlights its importance in these crops' cultivation and disease management strategies, emphasizing the need for careful monitoring and control measures in areas where these fruits are grown. Effective disease management practices include crop rotation, using resistant varieties, and proper sanitation, all tailored specifically to these hosts, thereby minimizing the impact of this pathogen on strawberry and raspberry production.

Considering the other options, while some fungi can have a wide host range, strawberry anthracnose is particularly focused on the aforementioned berries, rather than a broad spectrum of fruits or species like apples, pears, or crabapples which do not serve as primary hosts for this pathogen.
