Are a group of fungal diseases affecting the leaves and stems of plants. Leaves are most commonly affected most commonly, but rust can also be found occasionally on stems and even flowers and fruit.
Often pales markings will develop on the upper surfaces of leaves, which correspond with white, yellow, orange or dark-brown wart-like spots on the underside of the leaves. Yellow spores may be seen falling from the undersides of the affected leaves. Severely affected leaves often turn yellow, brown and fall prematurely often reducing the vigour of the plant. In some cases the plant can be killed.
Now you know what the problem is, and the damage it is doing, don't let your plant suffer.
