Pinoxaden is a new phenylpyrazoline herbicide classified as an acetyl-CoA carboxylase (ACC) inhibitor. Its mechanism of action involves inhibiting fatty acid synthesis, stopping cell growth and division, and disrupting the lipid structure of cell membranes, leading to weed death. It has systemic activity and is primarily used for controlling annual grassy weeds in barley fields.
Features and Application of Pinoxaden
Mode of Action:
- Systemic Absorption: Absorbed and translocated within the plant.
- ACC Inhibition: Inhibits acetyl-CoA carboxylase, disrupting fatty acid synthesis and cell membrane integrity.
Effective Against:
- Wild oats (Avena fatua)
- Foxtail (Setaria spp.)
- Barnyard grass (Echinochloa crus-galli)
Research and Efficacy
- Laboratory and Field Trials: Show excellent control of annual grassy weeds in barley fields, such as wild oats, foxtail, and barnyard grass.
