Circular brown spots begin occurring on the older, lower leaves in late June and July. The leaves begin to turn bright yellow, orange or red with dark small spots and fall off the tree. As the summer progresses, many infected trees will have dropped all but their newest leaves.
Fungicide treatments should be started in early summer when the spots are first noticed and continued every one to two week or every 7 to 14 days when the weather is warm and wet.
