There are five weeds declared noxious which are located in Riley County: Musk Thistle, Field Bindweed, Johnsongrass, Hoary Cress and Sericea Lespedeza.
No, Riley County can only sell herbicides for noxious weed control. We can make recommendations, but you must purchase the herbicides from your local dealer.
You only need a license to apply a restricted use pesticide (RUP). The only RUP that we sell is Tordon 22K. You must have a private applicator license to apply Tordon, but you may purchase the product and have a commercial applicator apply it for you if you are not licensed.
