Effects of Spruce Budworm Outbreaks on the Productivity and Stability of Balsam Fir Forests

Goal(s)/Objective(s): Reviews the effects of spruce budworm caused defoliation on forest productivity, including radial and volume growth of both individual trees and stands, top-kill of trees, and rate of mortality in stands.

Key Findings: Spruce budworm outbreaks definitely disrupt the short-term stability of forest ecosystems by causing widespread tree mortality and loss of wood production, which in turn cause major forest management problems.

Reduced Application Rates of Orthene Forest Spray Give Less Effective Spruce Budworm Control in Maine – 1978

Problem Addressed: Spruce Budworm

Goal(s)/Objective(s): Compare 4 different concentrations of acephate (tank mixes) applied at different volume rates.
