Herbicide treatments are completed and Peavy Arboretum is now open.

The OSU Research Forests also applied herbicides along the Highway 99 powerline right-of-way. All herbicide treatments were applied using backpack sprayers to target invasive plants.

Signs are posted at the treatment units and contain the application time, herbicide active ingredients, and re-entry interval. Signs will remain in place for one week.
