Butachlor

Chemical structure of Butachlor

Butachlor is a herbicide belonging to the class of chloroacetanilides. It is primarily used for the control of annual grasses and broadleaf weeds in rice paddies. Butachlor is applied to the soil and is absorbed by the roots and shoots of germinating weeds, inhibiting their growth.

Chemical Properties

Butachlor is a systemic herbicide with the chemical formula C₁₇H₂₆ClNO₂. It is a selective herbicide, meaning it targets specific types of plants while leaving the desired crop relatively unharmed. The compound is a chloroacetanilide, characterized by the presence of a chloroacetyl group attached to an aniline moiety.

Mode of Action

Butachlor works by inhibiting the synthesis of proteins and lipids in susceptible plants. It interferes with the biosynthesis of fatty acids, which are essential components of cell membranes. This disruption leads to the death of the weed seedlings before they can emerge from the soil.

Application

Butachlor is typically applied as a pre-emergence herbicide, meaning it is applied before the weeds have emerged from the soil. It is often used in rice cultivation, where it is applied to flooded fields. The herbicide is absorbed by the roots and shoots of the weeds, preventing them from growing.

Environmental Impact

The use of Butachlor can have environmental implications. It is important to follow recommended application rates and guidelines to minimize the risk of water pollution and soil contamination. Butachlor can persist in the environment and may affect non-target organisms if not used properly.

Safety and Handling

When handling Butachlor, it is important to use appropriate personal protective equipment (PPE) to avoid exposure. This includes wearing gloves, goggles, and protective clothing. Users should follow all safety instructions provided by the manufacturer to ensure safe application and handling.
