The Q&A Archives: Euonymous Losing Leaves & Dying

Question: I have several euonymous bushes in my back and front yards. Some bushes seem to be coated with a white dust. On the leaves, there are small white lines that look like some type of fungus. Last year, almost all of the leaves dropped from the inside of the bush but not the outside except on the top. Each spring I prune the bushes to shape them and this spring it does appear that some of the leaves are growing back on the inside but I still see this white dust coating the stems. The top part is not growing any leaves at all. What can I use to kill this (what I believe to be some kind of fungus)? These bushes are important to my landscape.

Answer: Unfortunately the fortunei group of Euonymous is subject to a number of foliage problems including mildew, leaf spots and scale. You might wish to take a sample to your County Extension (863-0110) for a definite diagnosis of the problem(s) and the most up to date recommendations for control. In the meantime, clean up and remove and destroy any clippings and fallen plant debris to help decrease reinfection.
