A Cooperative Pilot Study of the Insecticide Sumithion

Problem Addressed: Insecticide effects

Goal(s)/Objective(s): Evaluate the effectiveness of a selected treatment of Sumithion in controlling the spruce budworm and the effect of Sumithion on birds, fish, and aquatic invertebrates

Distribution and presistence of fenitrothion residues in foliage, soil and water in larose forest.

Problem Addressed: Insecticide residues in Larose forest.

Goal(s)/Objective(s): Summarize an operational experiment carried out in Larose Forest to study the persistence of aerially applied fenitrothion and its metabolites (the oxon analgue and 4-nitro-cresol) in white spruce foliage, soil and water samples collected from sprayed areas.

Key Findings: Degradation and persistence of fenitrothion findings are in reasonable agreement with those for the same chemical used in N.B. forests.
