Descripción:	In early 1998, symptoms of stem canker and necrotic spots on leaves, leaf veins, petioles, rachis, penduncles, capstems and berries were observed on plants in vineyards in the Submedio of the Sao Francisco Valley. Initially, the symptoms were observed on Red Globe and seedless grape cultivars up to three years old, during the flowering and beginnig of fruit bearing stages. The incidence of disease symptoms was 100% and in some cases yield losses were nearly total. Isolations from diseased plants yielded a bacterium which was identified as Xanthomonas campestris pv. viticola, after biochemical, physiological and pathogenicity tests. The disease has already been detected in vineyards in Petrolina country of Pernambuco State, Piaui State and also in Curaca, Casa Nova, Sento Se and Juazeiro countries in Bahia State.
