Once the leaves have rust spores it will be difficult to control but you can use a fungicide to keep the disease from spreading. Then next year, just as the trees begin to flower and leaf out, a spray program will help keep them disease-free. This year, rake the fallen leaves and remove them from the garden. In winter use a lime-sulfur (bordeaux) spray and follow the label directions for the necessary repeat treatments. Next summer your apple trees should be rust-free.

Best wishes with your garden!
