Acetochlor is a pre-emergence and early post-emergence herbicide belonging to the chloroacetanilide class. It is widely used to control annual grasses and broadleaf weeds in crops such as corn, soybean, cotton, sorghum, and peanuts.Acetochlor is valued for its broad-spectrum control, long residual activity, and crop safety, making it a reliable solution for modern weed management.
Acetochlor works as a VLCFA (Very Long Chain Fatty Acid) synthesis inhibitor:
Inhibits the synthesis of very long chain fatty acids in weed seedlings
Disrupts cell membrane formation and root development
Leads to growth inhibition and eventual death of young weeds
Most effective when applied to pre-emergence or early post-emergence seedlings
👉 Visible symptoms usually appear within 7–14 days, depending on weed species and environmental conditions.
✔ Broad-spectrum control – Effective against grasses and many broadleaf weeds
✔ Residual soil activity – Suppresses new weed emergence for several weeks
✔ Crop safety – Compatible with major crops like corn, soybean, cotton, and peanuts
✔ Flexible application – Can be applied pre-emergence or early post-emergence
✔ Low resistance risk – Different mode of action from ALS or ACCase inhibitors
⚠ Apply pre-emergence or at early seedling stage for optimal results
⚠ Avoid applying to crops under stress conditions (drought, waterlogging, high temperatures)
⚠ Prevent drift to sensitive crops
⚠ Always follow registered crops, dosage, and local regulations
⚠ Wear proper personal protective equipment (PPE) during application
Rotation with herbicides of different modes of action is recommended to reduce resistance risk.
