Skeletonweed..the silent invasion
Rush Skeletonweed, a perennial weed, continues to invade new areas in Umatilla County. I looked at a small patch of Skeletonweed near Athena, Oregon this week. Almost 25 years has passed since I was involved in the first sighting of Skeletonweed in our county. While it has not spread as quickly as we first thought it would, it has continued to move into new areas over the years.
Perennial weeds will likely be an increasing threat as we reduce the amount of tillage in our production system. Also as we plant perennial buffers along waterways and streams, perennial weeds like Canada Thistle, Russian Knapweed and Skeletonweed will likely get established and require more attention.
