I've been out of the farm supply business for several years and things do change but I can not think of any product that will help. The problem is that both Timothy and Orchard Grass are members of the grass family so anything you use will kill your lawn grass too.
Having said that,contact your local Agricultural Extension office or County agent or Farm Coop. They should be able to help you.
