Environmental Monitoring of the 1982 Spruce Budworm Spraying Program in Newfoundland

Goal(s)/Objective(s): Determine the impact of the aerial application of the pesticide Matacil on terrestrial insect, songbird and aquatic invertebrate communities over the course of one biological season

Key Findings: Matacil levels on balsam fir in the sprayed areas were low thoughout the study. Six of the 29 samples of balsam fir had Matacil levels over 1.0 ppm (maximum of 5.8 ppm). Levels following the second spray were somewhat higher than following the first. This is attributed to rainfall shortly after the first spray undoubtedly washed some of the pesticie away and a cumulative effect.
