Insect and Disease Conditions Report, 2004. Northeastern Area/Region 9

摘要

Populations of these perennial pests of arborvitae caused varying degrees of damage across the State of Maine. Arborvitae in northwestern Maine and eastern Washington County sustained the heaviest damage again in 2004. Many infested native stands as well as ornamentals showed signs of stress and increased mortality especially on sites affected by past drought. Damage was reported on 1,030 acres in central Vermont.
