Over the past 100 years, devil weed (Chromolaena odorata) introductions have spread to India, Africa, SE Asia, and the South Pacific islands. It is now one of the world’s worst 100 invasive species! An aggressive invader of disturbed soils and open areas, toxic to livestock, it takes over pastures and farmlands.
First detected on O’ahu in 2011, devil weed has spread beyond existing resources for island-wide eradication.
This page had information to help guide farmers and ranchers on Oʻahu to stop devil weed from impacting their operations.
