Colletotrichum fragariae, which causes strawberry anthracnose, has been found attacking Cassia obtusifolia in Florida. Isolates from this weed produced typical anthracnose symptoms on potted strawberry plants, and isolates from strawberry infected potted Cassia seedlings. Cassia obtusifolia is widely distributed in central Florida and may be a principal source of primary inoculum of C. fragariae.
