Dimension 2EW is also a pre-emergent herbicide like Surflan. Dimension 2EW is not specifically labeled for thistles and dandelion. Please click on the link for more information on treating these. If they are actively growing, you will want to apply a selective post-emergent herbicide. Battleship III is our most popular selective herbicide. The advanced "three-way" formulation contains Triclopyr, Fluroxypyr and MCPA in an easy-to-use liquid formulation. Battleship III controls annual and perennial broadleaf weeds including Dandelion, Chickweed, Black Medic, Knotweed, Plantain, Oxalis, Clover, Cocklebur, Thistle and many other species. Please refer to the product label to ensure it is safe to apply to your species of turfgrass.
