Oxyfluorfen

Oxyfluorfen is a herbicide used in the control of broadleaf weeds and grasses in a variety of crops. It is a member of the diphenyl ether group of herbicides, which also includes acifluorfen and lactofen. Oxyfluorfen works by inhibiting the enzyme protoporphyrinogen oxidase, which is necessary for chlorophyll production. Without chlorophyll, plants are unable to carry out photosynthesis and eventually die.

Mode of Action

Oxyfluorfen is a contact herbicide, meaning it must come into direct contact with the plant in order to be effective. It is typically applied to the soil surface and is activated by sunlight. Once activated, oxyfluorfen disrupts the process of cell division in the plant, leading to its death.

Use and Application

Oxyfluorfen is used in a variety of crops, including fruit trees, vineyards, vegetables, and ornamental plants. It is typically applied as a pre-emergence herbicide, meaning it is used before the weeds have emerged from the soil. However, it can also be used as a post-emergence herbicide on certain crops.

Safety and Environmental Impact

Like all herbicides, oxyfluorfen must be used responsibly to minimize its impact on the environment. It is classified as a moderate hazard by the World Health Organization, and can be harmful to aquatic life if it enters water bodies. However, when used correctly, oxyfluorfen can be an effective tool in integrated pest management strategies.
