Abstract

The exotic invasive plant Parthenium hysterophorus is invading rangelands in Africa while causing negative effects on the biodiversity, environment, economy, and human and animal health because eco-friendly control methods are lacking.

We conducted experiments to investigate the suppressive effects of forage legume plant species; Desmodium intortum (Fabaceae), Lablab purpureus (Fabaceae), and Medicago sativa (Fabaceae) in suppressing the growth of Parthenium hysterophorus.

Parthenium hysterophorus growth was suppressed when grown with fodder plant species at high density. However, the effect was mediated by the presence of Lablab purpureus.

Our work highlights the importance of competitive native plant diversity and density in rangeland management.

Moreover, this control method could be part of an integrated control toolkit being deployed in a community-based approach in other countries.
