The cut stump technology is probably the most effective means of killing mature Prosopis trees using the herbicide Triclon with active ingredients Triclopyr 480g/l . Stems are cut with a chainsaw as close to the ground as possible and the herbicide is applied to the stump within three minutes of cutting using a paintbrush. The young plants with less than 2 cm root collar diameter should be uprooted by hand. The treatment is repeated after three months on resprouting stumps.
