Control of currant bush (Carissa ovata) in developed brigalow (Acacia harpophylla) country

Abstract

Currant bush (Carissa ovata) is the major native woody weed invading sown buffel grass pastures in cleared brigalow (Acacia harpophylla) forests in Queensland. Stickraking followed by chisel ploughing is a viable alternative to and is more economical than herbicide treatment and blade ploughing for controlling currant bush. Chisel ploughing following stickraking gives good control of currant bush with no detrimental effect on existing buffel grass pasture. Stickraking alone is not sufficient to control currant bush.
