Have a hedge of Brush cherrys that has a black sticky substance on the leaf. What is it and how can I spray to get rid of it?

The sticky black substance is called sooty mold and it is an indication that your brush cherry shrubs are being attacked by a sucking insect. Mealybugs, scales and aphids are the usual culprits. When they feed they exude a sticky substance called honeydew which in time turns black. Look at the foliage just above the sticky leaves and you'll probably find a colony of insects. The control depends upon the insects you find: Insecticidal Soap or a Neem oil based insecticide are both effective against these insect pests. Be sure to apply according to label directions.
