The Forest Pest Management Institute conducted preliminary laboratory and field trials in 1981 assessing the environmental hazards of point source applications of aminocarb flowable (MATACIL 180F) formulations to streams (Holmes, 1981). In 1982 the evaluation of the flowable formulation was expanded to include impact assessment of double 70.0 g/ha MATACIL 180F + ATLOX 3409F + water and MATACIL 180F + Insecticide Diluent 585 applications under operational conditions to streams within forested areas in New Brunswick. The effects of these applications on stream benthos and indigenous salmonids are presented in this report. Effects on forest song birds in the same areas are presented in a separate report (Millikin 1982).
