First report of mixed infection by Pseudomonas syringae pathovars garcae and tabaci on coffee plantations

ABSTRACT: The bacterial-halo-blight ( Pseudomonas syringae pv. garcae ) is disseminated by the main coffee areas in the producing states of Brazil.

In mid-2015, samples of coffee leaves with symptoms of foliar lesions surrounded by yellow halo, were collected in coffee plantations in the State of Parana and fluorescent bacteria producing or not brown pigment in culture medium were isolated and determined as belonging to the Group I PLANT PROTECTION - Article First report of mixed infection by Pseudomonas syringae pathovars garcae and tabaci on coffee plantations Lucas Mateus Rivero Rodrigues 1 *, Gustavo Hiroshi Sera 2 , Oliveiro Guerreiro Filho 1 , Luis Otavio Saggion Beriam 3 , Irene Maria Gatti de Almeida 1.Instituto Agronomico - Centro de Cafe - Campinas (SP), Brazil.2.Instituto Agronomico do Parana - Area de Melhoramento e Genetica Vegetal - Londrina (PR), Brazil.3.Instituto Biologico - Laboratorio de Bacteriologia Vegetal - Campinas (SP), Brazil.
