[1][4] Diseased canes do not produce fruit, and as a result, this pathogen poses one of the largest threats to commercial blackberry production.

[6][1][5] The hosts of C. rubi are limited to the genus Rubus, which encompasses blackberries (both erect and trailing varieties), raspberries, dewberries, and boysenberries.

[1][4][7][8] In the United States, rosette disease of blackberry is commonly found in the southeast parts of the country encompassed by New Jersey, Illinois, and Texas.

[1] The disease spreads to new areas through infected nursery stock or the dispersion of wind borne spores.

[1] The first-year non-flowering canes, known as primocanes, are infected by conidia that are dispersed by C. rubi fruiting bodies.

In the case of severely infected plants, one can cut both the primocanes and floricanes down to the ground immediately after harvest.
