  • Project Description:
    The proponent (Dow AgroSciences) in conjunction with the Canadian Forest Service (CFS) propose to carry out an experimental research application of a biological control agent Spinosad (the active ingredient in Entrust 80W) against the balsam fir sawfly. Applications would be made aerially on three plots of 15 hectares each (45 hectares total) of selected silviculturally treated forest stands, forecast to receive moderate to severe balsam fir sawfly defoliation.
