If you spot new gorse plants on your property, immediate pull or treat to prevent a large infestation. Note control has been successful and to re-treat if necessary. Biological controlTwo biological controls for gorse, approved for release in Oregon, are a seed weevil and a spider mite.

Unfortunately, the seed weevil and the spider mite have not been effective for controlling gorse.Chemical controlOregon Department of Agriculture representative for follow the herbicide label carefully.
