Bean rust is a disease of the green bean that causes rust-colored pustules on the leaves. These pustules eventually rupture and eject thousands of spores into the air to be carried to other plants. [64] Each individual spore can produce a fresh pustule on a plant within a week; therefore untreated rust can rapidly reach epidemic levels. [64]
Rust fungi grow intracellularly, and make spore-producing fruiting bodies within or, more often, on the surfaces of affected plant parts. [3] Some rust species form perennial systemic infections that may cause plant deformities such as growth retardation, witch's broom, stem canker, galls, or hypertrophy of affected plant parts.
