Clethodim is a selective, systemic herbicide belonging to the cyclohexanedione family, primarily used for post-emergence control of annual and perennial grass weeds in various broadleaf crops. It inhibits acetyl-coenzyme A carboxylase (ACCase), an essential enzyme in fatty acid synthesis, leading to the cessation of cell growth and eventual plant death. Clethodim is effective against a wide range of grass species, including those resistant to other herbicides.

Used for post-emergence control of grass weeds in soybeans, cotton, canola, sugar beets, and vegetables.
Applied to ornamental crops and nurseries to prevent grass weed infestations.
Incorporated into integrated pest management (IPM) programs to combat herbicide-resistant grasses.
Store in a cool, dry, and well-ventilated area between 5–30°C (41–86°F).
Keep away from heat, open flames, and strong oxidizers.
Store in tightly closed containers to prevent spills and vapor release.
Available in 1 L, 5 L, and 20 L HDPE drums.
Clethodim is effective against a broad spectrum of annual and perennial grass weeds, including barnyardgrass, crabgrass, goosegrass, johnsongrass, and wild oats.
Clethodim inhibits acetyl-coenzyme A carboxylase (ACCase), an essential enzyme in fatty acid synthesis, causing cell growth to cease and eventually killing the plant.
Clethodim is used on soybeans, cotton, canola, sugar beets, vegetables (onions, carrots, potatoes), and various broadleaf crops.
Yes, Clethodim is registered for use on food crops, with established residue limits ensuring safety when applied according to regulations.
The recommended dosage varies by crop and weed severity, typically ranging from 0.5 to 2.0 pints per acre.
Compared to other grass herbicides, Clethodim provides post-emergence control, is highly selective, and effectively controls grass weeds resistant to ALS and triazine herbicides.
Clethodim has low toxicity to non-target plants and animals but should be used with caution in aquatic environments due to potential runoff concerns.
The pre-harvest interval (PHI) varies by crop; for soybeans, it is typically 14 days, while for carrots and potatoes, it is around 30 days.
