Cowpea is a very consumed legume in Brazil, mainly in the regions North and Northeast of Brazil, where it is considered as a source of basic protein for the local population. The average yield of the crop is 484 kg/ha, but it may be reduced by phytosanitary problems. The Embrapa Cowpea Breeding Program released a cultivar called BRS Novaera, aiming to improve productivity and resistance to plant pathogens. It is considered as highly resistant to the diseased known as coffee stain, moderately resistant to golden mosaic and susceptible to thread blight, powdery mildew and other viruses, with no references to the disease cercospora spot. In the monitoring carried out at the Demonstration Unit for the Production of Bean Seeds of Embrapa Amazônia Oriental, in Belém, PA, plants with symptoms of leaf spots similar to the cercospora spot were detected, which were analyzed in the Laboratory of Plant Pathology at Embrapa Amazônia Oriental. The causal agent of the leaf spots was the fungus Pseudocercospora cruenta.Keywords: leaf spot; Vigna unguiculata.
