Azaleas and Evergreens Fall Prey to Lace Bugs in May
Lace bug continues to be a problem for azaleas, rhododendron, sycamore and broad leafed evergreens, especially andromeda. The first signs of lace bugs are yellow spots on leaves, similar to mite damage, only much larger. As lace bugs feed, they produce brown varnish-like droppings that spot the underside of the leaves. Advanced damage from lace bugs results in a gray blotched appearance on leaves or leaves turning completely brown.
Plants should be treated in mid-May to early June when lace bugs are active. Using merit (imidacloprid) in the fall will help protect susceptable plants the following season. This can eliminate timing and weather related issues the following spring. While not lethal, lace bug injury inhibits the plants ability to produce chlorophyl which can allow the plant to become vulnerable to more damaging insects and disease. Heavy lace bug activity will also reduce a plants value aesthetically. To have your plants inspected for lace bug, contact a Tree Tech certified arborist today.
