Ten herbicide treatments were applied to two sites containing high infestation levels of Sweet Resinbush (Euryops subcarnosus sub. Vulgaris, originally known as Euryops multifidus). Granular or pelleted materials were applied prior to monsoonal rainstorms and foliar materials were applied after the rains had promoted foliar growth. The most effective treatment was a 25 pound per acre rate of Pronone 10G granules with an average control of 98.8% one year after application.
