Insect & Disease Control

Sometimes trees, shrubs, and hedges can become overrun with pests and this can stress the trees.

Dutch elm disease is caused by a member of the sac fungi affecting elm trees, and is spread by the elm bark beetle. The disease has been accidentally introduced into America and Europe, where it has devastated native populations of Elms.

The first symptom of infection is usually an upper branch of the tree with leaves starting to wither and yellow in summer, months before the normal autumnal leaf shedding. This progressively spreads to the rest of the tree. Eventually, the roots die, starved of nutrients from the leaves.

Scab diseases of trees and shrubs can disfigure the plant by producing unsightly dark spots on the leaves.

Blossoms and fruit can also be attacked and the vigour of the plant reduced as a result of premature defoliation.

Leaf rollers, the larvae of certain Tortricid moths, often feed and pupate within the protection of rolled-up leaves. Several species can cause problems ornamental trees —including ash, birch, box elder, elm, maple, poplar, rose, and willow—and is particularly damaging to deciduous and live oaks.

It also attacks numerous fruit and nut trees including apple, cranberries, cherry, pear, plum, prune and walnut.
