What causes black and orange marks on my plum leaves?

Our Advice:

A fungal disease called plum rust but there are very few fungicides available for use on edible plants now. Rake up all of the fallen leaves and get rid of them. Apply a Winter Wash. Next year, sprays of Copper Mixture from Vitax after flowering may help.
