Chemical control of Ligustrum lucidum.
Metsulfuron methyl, triclopyr, glyphosate, hexazinone, 2,4-D amine and 2,4-D acid were applied to L. lucidum of mixed maturity by stem injection, wet stem or cut stump methods, during trials in bushland at Toowoomba, Queensland. After 14 months stem injection of 1.2% a.i. metsulfuron and cut stump applications of 0.06% metsulfuron, 4.8% triclopyr and 3% 2,4-D and all gave >90% plant mortality. Of these treatments, stem injection of 1.2% metsulfuron methyl had the lowest cost and 0.06% metsulfuron methyl was the lowest cost cut stump treatment.
