Modes of Action

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
