A ac{\'a}cia-negra (Acacia mearnsii) {\'e} cultivada no Brasil, especialmente no Estado do Rio Grande do Sul, visando tanto {\`a} produ{\c c}{\~a}o de tanino, a partir da casca, quanto o uso da madeira para papel, celulose, carv{\~a}o, lenha e chapas de aglomerados. A gomose causada por Phytophthora nicotianae e P. boehmeriae, {\'e} o seu principal problema fitossanit{\'a}rio. Discute-se nesta revis{\~a}o a exist{\^e}ncia de dois padr{\~o}es distintos de sintomatologia da gomose de Phytophthora que t{\^e}m sido observados nas planta{\c c}{\~o}es brasileiras: gomose basal, associada a P. nicotianae, e gomose generalizada, mais associada a P. boehmeriae. S{\~a}o discutidos aspectos relacionados {\`a} etiologia, {\`a} epidemiologia e {\`a}s estrat{\'e}gias de controle.

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.
