註釋Knowledge of the appropriate time period (the stage of growth or point in season) for herbicide treatments on cutover sites in the boreal forest is important for achieving optimum control of the competing species and minimizing physical damage to the conifer crop trees. This paper reviews suggested application times for 2,4-D, glyphosate (Vision) and hexazinone (Velpar L, Pronone) as documented in the literature. Emphasis was placed on those results relevant to boreal conditions. Maritime studies and others are discussed separately, since climate and species with potential for competition with conifers are different than in the boreal forest of northern Ontario.
