If you think your trees have Apple Scab, WE CAN HELP! Contact us today for an estimate!
Leaf spot and Apple Scab are common problems seen in Crabapple trees. They are diseases caused by fungi that first affect emerging leaves in the spring during moist conditions. Although neither disease usually kills crabapples, they can cause heavy defoliation by mid-summer. Leaves and fruit become covered in brown spots and the tree becomes unsightly as it drops leaves and thins out. The best way to treat leaf spot and apple scab is to spray the trees with a fungicide in early spring when the leaves first emerge, often followed up with a second application 14-21 days later. After the tree has leafed out it becomes difficult to control either fungus. Both can be prevented with the same fungicide.
