The black wattle (Acacia mearnsii ) is cultivated in Brazil for bark tannin, paper, cellulose, plywood, charcoal and firewood production. Gummosis of Phytophthora, caused by P. nicotianae and P. boehmeriae is the main disease problem on black wattle. The existence of two distinct symptom patterns observed on plants in the commercial fields are: butt gummosis which is associated with P. nicotianae and general gummosis more related to P. boehmeriae. Etiological, epidemiological and control aspects of this disease are presented and discussed on this review.
