Field and laboratory studies were conducted by the Environmental Impact Section of the Forest Pest Management Institute in 1981 to assess the effects on Aquatic ecosystems of exposure to Matacil formulation either currently in use, or proposed for use, in spruce budworm control operations. The field studies were conducted in a small, headwater trout stream in the Goulais River watershed approximately 50 km northeast of Sault ste. Marie, Ontario. A preliminary analysis of the results of these field studies is presented in this report.
