Bacterial blight of coffee: the inoculum supply and avenues of infection
Epiphytic survival of Pseudomonas syringae pathovar garcae on coffee was clearly established. Field inoculation experiments clearly showed dispersal of inoculum occurs by rain splash. Secondary spread in the inoculation experiments resulted in leaf and twig blight, and entry into twigs occurred through unfolded expanding leaves (2 mm to 3 mm long) on sub-apical nodes. Such leaves enclose the apical bud. Secondary infection of mature leaves resulted in localized necrotic lesions, which did not spread into twigs. Post-inoculation rainfall pattern was an important weather variable that determined dispersal of inoculum, production of inoculum by infected twigs, and entry of bacteria into twigs
