Clethodim is a selective herbicide used to control annual and perennial grass species by inhibiting acetyl-CoA carboxylase activity. Clethodim is characterized by high water solubility, low volatility, and limited environmental persistence in soil and aquatic systems, with moderate toxicity to birds, fish, and pollinators such as honeybees, yet relatively low toxicity toward aquatic invertebrates and algae, thereby making it an effective yet environmentally manageable agrochemical.
