The distribution of scentless chamomile was mapped for highways and municipal roads throughout the province. The weed grows on 867 miles of provincial highway and 2814 miles of municipal roads. In Saskatchewan, 98 rural municipalities do not have the weed. Scentless chamomile was reported in 199 rural municipalities. The weed should be controlled to prevent further spread throughout the province. The scentless chamomile seed weevil (Omphalapion hookeri) and gall midge (Rhopalomyia tripleurospermi) have successfully established in the province. Their populations are increasing.
