Title: Oxyfluorfen safe to use engelmann spruce seedbeds. Forest Service research note

Technical Report ·
OSTI ID:6174361

Oxyfluorfen, a diphenylether herbicide, can be applied to Engelmann spruce nursery beds without significant damage to seedlings. Oxyfluorfen, applied at 0.5 lb/acre with preemergence timing for two years, reduced seedling dry mass. When the rate of herbicide application was reduced, the timing was delayed, or the applications were discontinued the second year, there was little damage to seedlings. Five of 10 herbicide treatments significantly reduced seedling densities compared to the no-treatment plots.
