Injection Methods for Controlling Albizia

Dr. James Leary, CTAHR Invasive Weed Specialist, conducts field trials at Maunawili Experiment Station, Oahu, targeting the invasive tree Albizia (Falcataria moluccana; syn. Albizia moluccana, Albizia falcata, Albizia falcataria, Adenanthera falcataria, Paraserianthes falcataria). Using Milestone® VM (active ingredient: aminopyralid), he researches two application methods: drill application vs. frill cut.
A second trial compares the effects of three different herbicides on albizia: 2,4-D® (active ingredient: 2,4-Dichlorophenol), Garlon®4 Plus (active ingredient: triclopyr), and Milestone® VM (active ingredient: aminopyralid).
Preliminary results are shown after 1 week, 2 weeks, and 5 weeks. Partial funding provided by the USDA via the RREA and TSTAR programs.
