tree service in Lake Orion, MI


Apple Scab is a foliar disease that affects many crabapple varieties in the southeast Michigan area. As the Apple Scab spores form, lesions develop a velvety brown appearance on the leaves of the crabapple tree. As leaves age and the disease progressed, they turn yellow and fall from the tree starting in early to mid summer. In some cases, susceptible crabapples and apples may be defoliated by late June. Although Apple Scab is not terribly injurious to trees, it can give the tree an unsightly appearance. However, yearly premature leaf drop on crabapple trees does cause stress. Apple Scab is highly dependent upon weather conditions, especially temperature and humidity. With our cool, wet spring weather we anticipate that there will be some degree of Apple Scab infection on susceptible cultivars every year.

Apple Scab Control

Control of Apple Scab is achieved through a series of fungicide treatments. Fungicide applications start soon after bud break and are repeated at 2 - 3 week intervals.  Removing the infected, fallen crabapple leaves can help reduce the spread of Apple Scab.  However, Apple Scab is so common, and spores so readily dispersed, that infection is still likely to occur. If you have a susceptible crabapple species in your landscape it will probably need to be sprayed every year to reduce the level of Apple Scab infection.

What Else Can Help Your Crabapple

When your crabapple tree loses its leaves too early in the summer the tree loses its ability to manufacture food for itself and it puts the tree under stress. Fertilizing your crabapple and spraying, when needed, to keep the tree free of insect pests will help keep your tree as healthy as possible
