  • 2,4-dichlorophenoxyacetic acid (2,4-D)
  • 2,4-dichlorophenoxy butyric acid (2,4-DB)
  • 2,4-dichlorophenoxy propionic acid (2,4-DP)
  • 2-methyl-4-chlorophenoxyacetic acid (MCPA)
  • 3,6-dichloro-o-anisic acid (dicamba)
  • 3,4-dichloropropionanilide (propanil)
  • 5-bromo-3-sec-butyl-6-methyluracil (bromacil)
  • 2,4-bis(isopropylamino)-6-methoxy-s-triazine (prometon)
  • 3,7-dichloro-8-quinolinecarboxylic acid (quinclorac)
  • devices using the active ingredients sodium fluoroacetate (Compound 1080) and sodium cyanide (M44), in any quantity, for livestock predation
