Abstract: Herbicidal compositions are provided that include a herbicidally synergistic amount of at least one at least one photosynthesis II inhibitor and a herbicidally synergistic amount of at least one protoporphyrinogen oxidase (PPO). The herbicidal composition is synergistically effective against annual and perennial broadleaf weeds, grassy weeds, and sedges. Methods of burndown treatment and control of undesirable vegetation are also provided.

Abstract: The invention provides herbicidal compositions and methods for weed control with the herbicidal compositions comprising auxin or auxin-like herbicide and ethoxylated lecithin. The undesired vegetation may be controlled using the herbicidal compositions and methods within and without damage to agricultural crops, turf grasses, or ornamental plants. The herbicidal compositions and methods of use disclosed provide for the improvement in post-emergence undesired vegetation control.
