-Use a fungicide that lists Scab on the label.
Start spraying in late April before the leaves emerge. (Buds will have a pink tinge to them.)
Spray again 7-10 days after the first spray (just before the flowers start to open).
Do not spray during flower bloom. This can kill the bees which pollinate the flowers.
Apply a third spray when flower petal drop is 3/4 completed.
Continue spraying at 7-10 day intervals until mid-late June. (A total of about 6 times.)
Spraying can cease when warmer and dryer weather becomes the norm.
-Rake up and dispose of fallen leaves during the growing season. (These leaves may reinfect the tree).
