Hi-Yield Range and Pasture Dicamba + D will control Russian thistle in pasture areas. It can be used on hay grasses, although the label does not specifically list Timothy grass as tolerant. We would recommend testing application over a small area before treating a larger area. Since this product is now discontinued, we recommend Weedmaster instead.
