Many homeowners want “organic” choices when it comes to selecting weed killers. Fortunately, there are several choices for both selective and non-selective weed control.
Vinegar has been touted as a herbicide but the kitchen version is too weak to do much damage. Industrial acetic acid will kill weeds but I consider it too dangerous to recommend.
There are other products from which to choose:
Non-selective (kills anything it touches);
ammonium nonanoate BioSafe (click for sources)
citrus oil Avenger (click for sources)
citric acid and clove oil Bonide BurnOut (click for sources)
Selective (kills broadleafed weeds but not grass)
