Papaya' Papaya', bacterial disease, symptoms, etiology.Abstract
This is the first report of occurrence of Pseudomonas syringae in papaya in Rio Grande do Sul State. The disease was verified on seedlings with 5 to 7 cm of height and 4 to 6 definitive leaves, about 15 days after the emergency, initially on 'Golden' and after on Sunrise Solo, S. Solo - Diva and S. Solo - M5 cultivars. Disease shows up as small water-soaking leaf spot, begins in the borders of the leaves, and increases in size and develops to brown necrotic lesion and irregular shape. Very often a chlorotic halo is formed between the necrotic and healthy tissue.
