• Orange hawkweed is a Priority 2A state listed noxious weed in the state of Montana. This species is difficult to control because of its ability to spread by rhizomatous or above ground ‘runners’ that start new plants.
    UAF Cooperative Extension Archive, University of Alaska - Fairbanks, Bugwood.org

  • Canada thistle is difficult to control because it is a creeping perennial plant that reproduces through vegetative buds in its root system and from the seeds it produces each year.
    Bonsak Hammeraas, Bioforsk - Norwegian Institute for Agricultural and Environmental Research, Bugwood.org

  • The larva of the leafy spurge hawk moth (Hyles euphorbiae) is an introduced biological control agent that feeds on leafy spurge. Biological control agents are natural predators or enemies of a plant species that feed on those plants and help to reduce or control populations helping to prevent their spread.
    Whitney Cranshaw, Colorado State University, Bugwood.org

  • Yellow toadflax is a Priority 2B state listed noxious weed in Montana.  Priority 2B weeds 'are abundant in Montana and widespread in many counties.'
