Flazasulfuron

Flazasulfuron is a sulfonylurea herbicide that is used for the control of a wide range of weed species. It is a systemic herbicide, absorbed by the roots and foliage, with translocation throughout the plant.

Chemistry

Flazasulfuron is a sulfonylurea compound, a group of herbicides that inhibit the enzyme acetolactate synthase (ALS). This enzyme is involved in the production of the amino acids valine, leucine, and isoleucine. By inhibiting this enzyme, flazasulfuron prevents the plant from synthesizing these essential amino acids, leading to plant death.

Use

Flazasulfuron is used for the control of a wide range of weed species, including broadleaf weeds, grass weeds, and some sedge species. It is used in a variety of settings, including turf, orchards, and non-crop areas.

Toxicity

Flazasulfuron has low toxicity to mammals, birds, and fish. However, it can be harmful to non-target plants if it is applied inappropriately. It is classified as a Category III pesticide by the Environmental Protection Agency (EPA), indicating that it has a low potential for causing acute harm to humans.

Environmental Fate

Flazasulfuron is moderately persistent in the environment, with a half-life in soil of between 30 and 60 days. It is highly soluble in water and can potentially leach into groundwater. It is not volatile, so it is unlikely to be transported in the air.
