Prostrate Knotweed
Metsulfuron at 0.5 oz per acre or dicamba (Banvel, Vanquish) at 0.5 lb per acre will control prostrate knotweed. Celsius WG (thiencarbazone + iodosulfuron + dicamba) should be effective on lespedeza. There are many combination products that contain 2, 4-D and dicamba including Trimec 992 and Speedzone.
