Biocontrol of Yellow Toadflax using Rhinusa pilosa, in Prince Albert National Park

Yellow toadflax is a widely distributed perennial invasive plant that reproduces by seed and extensive creeping rhizome. The plant is extremely hardy and  has the ability to densely infest large areas and crowd out native vegetation, making it a threat to ecological integrity in Prince Albert National Park. Herbicide spraying of yellow toadflax has occurred in several locations in Prince Albert National Park with limited success. Using a biological control agent offers an additional option for control of this species in a manner that is not nearly so labour intensive.  Prince Albert National Park will be working with Agriculture and Agri-food Canada to carry out trials of Rhinusa pilosa in up to three affected locations - Prospect Point, Rabbit Cabin area and 12 Mile Meadow. Weevils will be obtained from Agriculture and Agri-foods Canada at no charge and will be released at the sites in late summer.
