Late Summer/Fall Tree and Shrub Care

Lacebugs, whitefly, aphids, mites, and weevils are serious pests of many ornamentals. Today’s treatment will control these pests for a limited time. We did not treat plants that are pest free; only the plantings that need help are treated. Rainfall or overhead irrigation will not affect this spray after it has dried.

Webworms are a common late summer pest, identifiable by the silky nests they build on the branches of numerous species of trees. This pest overwinters in a cocoon that is concealed in ground litter, cracks and crevices of the tree, or in the soil. Adult Webworm moths first appear in Summer, and deposit their egg masses on the undersurface of the leaves. After about 7 days, the larvae hatch and immediately make a web over the foliage on which they feed. Webworms build their nest around their food supply; they do not go looking for food. As they grow, they enlarge the web. These webs may sometimes surround 2-3 feet of infested branch. After about 6 weeks, mature larvae leave the web and build a cocoon.

Mites can attack almost any plant in autumn, and can be very damaging. Mite damage shows as bleaching on foliage. Our treatments target two species of mites, the Two-Spotted Mite and the European Red Mite. Predator mites and other beneficial insects are not harmed by this treatment.

Cherry Bark Tortrix

Cherry Bark Tortrix attacks practically all rosaceous trees in the Northwest. This includes apples, cherries, plums, apricots, almonds, peaches, laurels, quince, firethorns, photinia and hawthorns. Damage to the tree is noticeable by dieback and premature wilting of the canopy. High populations can girdle and kill trees. The larvae of the CBT construct and visit their frass tubes with diligence in the spring and fall seasons. Your technician will inspect any susceptible trees in your landscape and treat for CBT if necessary.

Fruit Tree Treatments

We treat fruit trees with EverGreen EC 60-6®, a biological insecticide that is safe for use on all ornamentals and fruit trees without restriction. European and bacterial cankers infect fruit and flowering trees in our area. These diseases are spread by airborne spores, rainfall, or overhead irrigation. Their attack weakens limbs and branches, and can spread to the leaves and fruit. Infected trees should be pruned to eliminate as many of the cankers as possible. Treatment with copper sulfate may have been applied today to help limit the spread of some of these diseases. It is safe to harvest, wash and eat treated fruit after 24 hours.
