    Ocorrência de Meloidogyne coffeicola em cafeeiros do município de Coromandel, Região do Alto Paranaíba em Minas Gerais
    (Sociedade Brasileira de Fitopatologia (SBF), 2004-04-26) Castro, José M. C.; Campos, Vicente P.; Dutra, Marcos R.
    Coffee (Coffea arabica) plantations showing symptoms of decline, such as peeled and rough roots and fewer side rootlets were observed in the State of Minas Gerais, Brazil. Meloidogyne sp. females were obtained from thicker roots, and processed for perineal patterns and a-esterase electrophoresis analysis. It was concluded that M. coffeicola was the causal agent. The nematode incidence was occurring with field symptom patterns similar to those observed on coffee plantations of the State of Paraná, where most damage caused by M. coffeicola has been reported.

    (Sociedade Brasileira de Fitopatologia (SBF), 2003-03-24) Castro, José M. C.; Campos, Vicente P.; Naves, Rosemeire L.
    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.
