Japanese barberry ‘Crimson Pygmy’, Crape myrtle ‘Byers Hardy Lavender’ and azalea ‘Girard Scarlet’ were treated with either Southern weedgrass control (pendimethalin) at 3.4 kg a.i./ha (3.3 a.i.lb/A) or Ornamental Herbicide-2 (oxyfluorfen + pendimethalin) at 3.4 kg a.i./ha (3.3 lb a.i./A) or 6.7 kg a.i./ha (6.6 lb a.i./A) prior to simulated shipping in an enclosed environment. No injury was observed on any plants as a result of herbicide treatments.
