To control this disease, spray with a labeled fungicide in the spring and repeat until dry weather arrives or plant resistant cultivars such as 'Mojave', 'Shawnee' or'Teton'. This summer I conducted a fungicide trial to protect flowering dogwood against powdery mildew infection. I can report that all the labeled fungicides tested including Eagle, Banner MAXX, Cleary's 3336, and Bayleton, win provide excellent control. The treated trees are just now beginning to show normal red fall color, as opposed to the blotchy reddening from powdery mildew infection and have a full complement of leaves. What's Hot Oak lace bug has been especially common this season.
Leaves look pale yellow or scorched.
You will see the lace bugs on underneath leaf surfaces on closer inspection. Banded woolly bears are migrating. We hope you have found the information timely and of use in your business or job. In a few weeks we will be sending an evaluation and resubscription form. We appreciate your comments.
