Cercosporella rubi
Cercosporella rubi (commonly called double blossom[1] or witches' broom[2]) is a plant pathogen which causes rosette disease of blackberry. The disease is particularly prevalent in the southeast of the USA, where it poses one of the largest threats to commercial blackberry production.[3][4][1] The disease causes witch's broom symptoms as well as double blossoms, and can severely reduce yield.[3]
