Ocorrência de Meloidogyne paranaensis em cafeeiros na região do Alto Paranaíba em Minas Gerais

Abstract

Coffee (Coffea arabica) plantations showing symptoms of decline, with peeled and rough roots and fewer side rootlets were observed in the State of Minas Gerais, Brazil. Meloidogyne spp. females were obtained from the thicker roots and processed for perineal patterns and α-esterase electrophoresis analysis. Meloidogyne paranaensis was determined to be the main cause of the decline. The incidende and field symptom patterns found were similar to those observed on coffee plantations in the State of São Paulo and Paraná, where most damage caused by M. paranaensis has been reported.
