Synanthedon exitiosa
Peachtree Borer can be found throughout the United States and Canada east of the Rocky Mountains wherever trees in the Prunus species are grown. The larvae of the Peachtree borer feed on the cambium near the base of tree trunks and in the upper roots. The feeding damage disrupts the flow of water and nutrients within the tree. The result is a structurally weakened tree with reduced vigor. Young trees may be completely girdled and killed by Peachtree Borer.
TREES AND SHRUBS ATTACKED BY PEACHTREE BORER
Any tree in the Prunus genus can be a host to Peachtree Borer. This includes Apricot, Cherry, Nectarine, Peach, Plum, and Prune trees.
SYMPTOMS OF PEACHTREE BORER INFESTATION
Due to the reduced flow of water to the upper canopy tree leaves may be wilted or brown. Brown leaves will temporarily remain on the tree. Sap may be seen coming from borer exit holes near the base of the tree trunk or on larger exposed tree roots. A high level of Peachtree Borer infestation may cause a tree to break off near the base in high winds.
HOW TO CONTROL PEACHTREE BORER
Cultural Options
Like many borer insects, Peachtree Borers are attracted to stressed trees. Tree fertilization and watering during drought will minimize plant stress. Peachtree Borers are attracted to wounds, so keep mowing equipment away from tree trunks by mulching around trees.
Pesticide Options
Protective tree spraying can be done just before or during egg hatch to prevent the larvae from entering the tree. Tree spraying should be directed to the lower trunk and the ground in the immediate vicinity of the tree. More than one tree spraying treatment should be applied for optimum effectiveness.
