Stinger™ herbicide at 20 g 100 L-1 of water for blackberry (Rubus fruticosus L. agg.) and 30 g 100 L-1 of water for gorse (Ulex europaeus L.), applied by high volume handgun equipment, gave good regrowth suppression two seasons after the initial application when compared to the equivalent rate of metsulfuron-methyl alone. Stinger also gave residual control of secondary broadleaf weeds such as broom (Genista sp.) and thistles (e.g. Cirsium vulgare (Savi) Ten.), two seasons after the initial application with no effect on grass pastures.
