Powdery Mildew Tree Disease

I've taken the past few weeks to blog about some common tree diseases.  There are still a few left on  my list to cover.  I bet you never thought that our trees are susceptible to so many different fungi and diseases!
The next common tree disease on my list is called powdery mildew tree disease.  It is a common disease that appears as a white powdery substance on the leaf surface. The powdery appearance comes from millions of tiny fungal spores, which are spread in air currents to cause new infections. It attacks all kinds of trees. Trees most commonly affected by powdery mildew are linden, crabapple, catalpa and chokecherry, but almost any tree or shrub can get powdery mildew.


Powdery mildew is a product of moist conditions and is usually seen in the wetter spring and fall seasons. This humidity-loving fungi can be controlled if moisture can be controlled.
Don't plant trees in heavily-shaded areas and provide plenty of space for air movement and growing room. Prune the tree for effective air movement.


If necessary, spray with wettable sulfur at the recommended rate specified on the label. Sulfur may injure tender foliage, especially in hot weather so be careful. Do not use sulfur on walnuts, as injury may occur. Other fungicides can also be used under certain conditions. Check with your local tree service for more information.  If you are local to Chicagoland, Trees "R" Us, Inc. is the tree service for you!
