Pasture Weed Control Database
This weed is an indicator of poor soil fertility and weak, thin pastures. Spray Bitterweed before it flowers. Bitterweed is readily controlled with 2,4-D amine at 1 to 2 pt/A applied in May or early June. Cimarron Plus, metsulfuron 60 DF, Grazon P+D, GrazonNext HL and Dicamba + 2,4-D also control Bitterweed.
