Ash Plant Bug
The ash plant bug attacks green ash in the prairie provinces. These sucking insects overwinter in egg stage, which are laid in the bark of the tree in autumn. They emerge in the spring and feed on the underside of the leaves. The first adults appear in midsummer. They are light in color with pinkish margins and are approximately 5 mm long. These insects damage the tree, causing a mottling of the foliage, and a premature leaf drop.
To control these plant bugs one can paint Cygon 2-E around the trunk of the green ash trees. An one inch band can be painted on young trees (up to ten years).
