The results of an across-Canada survey into the past, present, and future use of herbicides in forestry are presented. Based on a response of more than 60% return of 250 questionaires sent, herbicide use potential is not being met. In Ontario, the most commonly used herbicides are simazine, mainly for grass control, and the low volatile esters 2,4-D and 2,4,5-T, used either alone or in combination for conifer release from overtopping hardwood vegetation, for site preparation and weed control in young hardwood and conifer plantations, and for the general control of brush along roadsides.It is suggested that greater communication is necessary between the field forester and the chemical manufacturer before herbicide versatility can be realized and, for their use in the environment to be accepted, communication must also include the general public.
