Distribution
Prevention and Control
Control
Cultural Control
In its native range, P. caespitosa occurs mainly on nutrient-poor soils. Thus, fertilizers can control these species by increasing the competitive ability of more desirable pasture species (Wilson and Callihan, 1999). The main method of control at present is to improve land by the application of fertilizer and over sowing with pasture species. However, these species remain a problem on areas with low economic growth potential, abandoned land, reserves and national parks (Grundy, 1989).
Mechanical Control
Mechanical control of P. caespitosa has had limited success. Digging the plants or otherwise disturbing the stolons, rhizomes, or roots only serves to spread and multiply the weed, since plants can grow from buds on small roots, stolons and rhizome fragments (Wilson and Callihan, 1999). Due to its mat-forming growth, mowing does not kill P. caespitosa.
Chemical Control
Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any specific chemical control recommendations. For further information, we recommend you visit the following resources:
