Prevention and Control Top of page Due to the variable regulations around de registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control.
Mechanical control must be practiced over a several year period as dormant seeds will continue to germinate. Seedlings and young plants should be hand-pulled and removed from treated areas, while large plants should be cut with specialized equipment due to the presence of thorns.
There is no information or data available on the biological or chemical control of this species. Further investigation is needed. Catalogue of the Seed Plants of the West Indies.
