Vegetation control trials in Alberta and Manitoba in 1980–85 tested nine herbicides to determine their capabilities for conifer release, chemical thinning, and site preparation. The herbicides tested were hexazinone in liquid, grid ball (10 and 20%), and granular (10 and 20%) formulations, metsulfuron methyl, fluazifop–butyl, bromacil, and fosamine ammonium. Data were obtained on conifer growth and tolerance to the herbicides, weed control, optimum timing of application, techniques, and equipment performance.
