Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers.Clopyralid is in the picolinic acid family of herbicides, which also includes aminopyralid, picloram, triclopyr, and several less common herbicides.
The weevil was found to be very effective in reducing the spread of invasive thistles, particularly musk thistle, but also welted, Italian, bull, milk, and other thistles. However, the weevil will also readily attack native thistles of genus Cirsium , [ 1 ] in some cases contributing to population decline. [ 2 ]

The main threat to this species is probably biological pest control agents released to control non-native thistle species. For example, the weevil Rhinocyllus conicus was released to control musk thistle, Carduus nutans, but once in the wild it also attacked many native species, including native thistles such as C. perplexans.
