The efficacy and tolerance of the herbicide oxyfluorfen (Goal) were evaluated for use in British Columbia's forest nurseries. This report details trials conducted in 1987 to assess the effectiveness of oxyfluorfen in controlling herbaceous weeds, which pose a significant threat to seedling growth and survival by competing for resources and harboring pests. The study focused on the tolerance of bareroot Douglas-fir and lodgepole pine seedlings (both 1+0 and 2+0 stock) to this herbicide, building upon its established use in U.S. forest nurseries. The research aimed to gather data for the potential registration of oxyfluorfen in Canada, following a standardized trial design coordinated by the Canadian Forest Nursery Weed Management Association.

This report presents technical findings from a specific agricultural trial, likely intended for forestry professionals and researchers involved in nursery management and herbicide application. The data generated would inform decisions regarding the registration and practical use of oxyfluorfen in Canadian forest nurseries, particularly in British Columbia. Its focus on efficacy and seedling tolerance suggests a practical, evidence-based approach to weed control challenges.
