Ocurrence of Pseudomonas syringae in papaya seedlings (Carica papaya L.) in Rio Grande do Sul state
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.
