Using Aminopyralid Preemergent in Pastures for Western Ragweed Control
Western ragweed (Ambrosia psilostachya) is considered one of the most common weeds in pastures and rangeland in the Southern Great Plains. It is an aggressive competitor with grasses and is generally considered unpalatable to cattle (Vermeire et al., 2013). It is found in abundance in at least 30 states, Canada and Mexico (Pavek, 1992).
