Conteúdo: 	The incidence, economic importance and symptoms of leaf spot diseases is reviewed, with particular reference to their status in East Africa. Particular emphasis is given to sigatoka (Mycosphaerella musicola) and black leaf streak ("black sigatoka", M. fijiensis) but pathogens causing leaf freckle and Cordana leaf spot are also discussed. Mixed infections of pathogens are common and leaf spot diseases must be distinguished from leaf symptoms reflecting stress caused by other diseases, pests and poor soil conditions. Assessment techniques, based on leaf area affecccted by disease, have been well developed in plantation crops of dessert bananas where leaf area reduction relates directly to yield depression. In East Africa other stress factors may be limiting and the incidence of leaf spot diseases interacts with agronomic factors and the incidence of other pests and diseases.
