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.
