What are the brown spots on my apple tree leaves?

The brown spots on your apple tree leaves are most likely due to a fungal infection called cedar-apple rust. This disease is caused by a fungus that spends part of its life cycle on cedar trees and the other part on apple trees. The fungus produces orange-brown galls on cedar trees in the spring, and these galls release spores that infect apple leaves in the summer. The infection causes small, brownish spots to form on the upper surface of the leaves. As the spots enlarge, they turn brown, and eventually the entire leaf may turn brown and fall off the tree.
