We have a really bad sand burr problem that came in with the seed planting. Pasture is 4 yrs estAblished.
Unfortunately, Rezilon Pre Emergent Herbicide is not labeled or safe to spray bluestem or Bdahl but it does not include them either. Rezilon Pre-emergent can be used on pastures or hayfields that have been established for over a year but it is not "for use on intensively managed cool season (C3) grass pastures or hayfields such as timothy (Phleum pratense), fescues (Festuca species), bluegrass (Poa spp.) and perennnial ryegrass (Lolium perenne). Some cool season grass species may be injured or killed by Rezilon" per the product label. We recommend contacting your local extension office or department of agriculture.
