Leaf rust usually is not a singular fungal infection, but a collection of fungi that grow on the foliar portion of a plant. The most common sign of leaf rust is the development of brown spots on the back side of leaves. While most of the time these spots may appear to be brown, they can also be reddish, white, yellow, orange or black, depending on the type of plant and the rust fungi growing on it.
To get rid of it....Treat the plant or plants with a copper or sulfur-based fungicide every 10 to 14 days. Be aware, though, that fungi sometimes develop a tolerance when exposed to the same fungicide after awhile. If it seems to you that this may be happening, switch to another fungicide for a few weeks.
The simplest homemade fungicide is simply mixing two aspirin per quart of plain water. Baking soda, too.
Remove leaves, but don't throw in compost....spreads like wild fire!!
Avoid watering plants too much or too often. Rust fungus is much more prevalent in hot, humid environments or in conditions where there is excessive moisture from over watering.
Increase the circulation of air around your plants by providing plenty of space between individual plantings. Prune flowering plants and shrubs regularly to prevent pockets of dense growth that can block the flow of air.
Hope that helps!
