Butafenacil

Butafenacil is a herbicide that is used to control a wide range of weed species. It is a member of the pyrimidinedione class of herbicides, which work by inhibiting the process of photosynthesis in target plants.

Chemistry

Butafenacil is a synthetic compound that is not naturally occurring. It is a white, crystalline solid with a slight odor. The chemical formula for butafenacil is C19H16F3N3O2. It is soluble in water and most organic solvents.

Mode of Action

Butafenacil works by inhibiting the process of photosynthesis in plants. It does this by binding to the quinone-binding protein in the chloroplast, which prevents the transfer of electrons from the quinone to the cytochrome complex. This stops the production of ATP and NADPH, which are essential for the growth and survival of the plant.

Uses

Butafenacil is used to control a wide range of weed species, including both broadleaf and grass weeds. It is used in a variety of settings, including agricultural, horticultural, and landscaping applications. It can be applied as a pre-emergent or post-emergent herbicide, depending on the specific weed species and growth stage.

Safety

Like all herbicides, butafenacil should be used with caution. It can be harmful if swallowed, inhaled, or absorbed through the skin. It can also cause eye irritation. Appropriate personal protective equipment should be worn when handling or applying this herbicide.

Environmental Impact

Butafenacil is considered to be moderately persistent in the environment, with a half-life in soil of between 30 and 60 days. It has low mobility in soil, which means it is unlikely to leach into groundwater. However, it is highly toxic to aquatic organisms and should not be applied near water bodies.
