How to Manage Pests

Pests in Gardens and Landscapes

Cherry leaf spot—Blumeriella jaapii

Cherry leaf spot causes spots to appear on the upper surfaces of leaves. Spots may range in color from a light gray or brown to a dark purplish color and an overall yellowing of the leaf may occur. As the affected tissue dries, the internal tissue may fall out, giving the leaf a tattered appearance. The undersides of leaves may be covered with spores. Leaves may dry and fall off the tree. Fruit may be spotted and soft.

Solutions

Remove diseased leaves as soon as they appear and destroy them. Removing all older leaves at the end of each season also may be helpful in reducing carryover of the pathogens. Some fungicides, such as flowable sulfur, are available to the home gardener, but are rarely needed.
