Chemical Control
Biosecurity Queensland (2013) lists permitted herbicides for control of C. grandiflorum as glyphosate as a cut stump treatment, and fluroxypyr and 2-4, D amine for spot spraying. Plants can be cut at waist height for glyphosate treatment in dense infestations, leaving supporting vegetation in place to rot away, and any resprout can then also be sprayed. However, management with herbicides is often made difficult because of their close proximity to water sources, and native species can be affected (PIER, 2015).
