Acetochlor

Acetochlor is a herbicide primarily used for weed control in the production of corn, soybeans, and other crops. It belongs to the class of chemical compounds known as chloroacetanilides, which are amides with a chlorine atom attached to the acetanilide portion of the molecule.

Chemical Properties

Acetochlor has the chemical formula C14H20ClNO2 and a molecular weight of 269.77 g/mol. It is a brown liquid with a mild, sweet odor. It is not soluble in water and has a low volatility.

Mode of Action

Acetochlor works by inhibiting the growth of weeds by disrupting protein synthesis. It is absorbed by the plants through their shoots and roots and transported to the growth points of the weeds.

Environmental Impact

Acetochlor is classified as a persistent organic pollutant due to its potential to persist in the environment, bioaccumulate, and have potential adverse effects on human health and the environment. It can contaminate groundwater and may be toxic to aquatic organisms.

Health Effects

Exposure to acetochlor can cause irritation to the eyes, skin, and respiratory tract. Long-term exposure can lead to more serious health effects such as damage to the liver, kidneys, and lungs.

Regulation

In the United States, acetochlor is regulated by the Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). It is classified as a Restricted Use Pesticide (RUP).
