Brief description of what a "mode of action" is and why it is significant in choosing pesticides (especially herbicides)

Pages with information on each mode of action

  • Acetolactate synthase (ALS) or Acetohydroxy acid synthase (AHAS) inhibitors
  • Acetyl CoA carboxylase (ACCase) inhibitors
  • Carotenoid biosynthesis inhibitors
  • Cellulose inhibitors (Cell wall synthesis)
  • EPSP synthase inhibitors
  • Glutamine synthesis inhibitors
  • Lipid synthesis inhibitors (not ACCase)
  • Long-chain fatty acid inhibitors
  • Microtubule inhibitors
  • Photosystem I (PSI) electron diverter
  • Photosysytem II inhibitors
  • PPO inhibitors (protoporphyrinogen oxidase)
  • Synthetic auxins
  • Unknown mode of action
