DESCRIPTION
WHO CAUSES IT?
Rust is a fungal disease that affects a wide variety of plants, including rose bushes. This disease is caused by fungi of the genus Puccinia, which infect the leaves and other tissues of the plant, causing significant damage if not properly controlled.

In rose bushes, rust produces a series of characteristic symptoms. These include the appearance of yellow, orange or brown Taches on the leaves of the plant, often accompanied by a fine rust-colored powder on the underside of the leaves. Over time, the Taches can expand and merge, causing defoliation and weakening of the plant.
