• Controlling Bitterweed with Fall and Winter Applications of 2,4-D Amine

      Bitterweed can be effectively controlled in central Texas with 2,4-D (2,4-Dichlorophenoxyacetic acid) amine between November 1 and January 15. To minimize damage to associated annual forbs, 2,4-D should be applied in late December or January. A rate of 1/2 to 1 lb a.e./acre of 2,4-D will give excellent control of bitterweed. However, spraying with 2,4-D has no long-term benefits under a good range management program. Its primary value is to kill bitterweed during wet winters when it is abundant. This minimizes death losses of sheep and increases the vigor of perennial grasses for 1 or 2 years.
