MEFLUIDIDE Usage And Synthesis

Chemical Properties

White crystalline solid. Some formulations are a dark brown liquid.

Uses

Plant growth regulator and herbicide used in lawns, turf, grassland, industrial areas and areas where grass cutting is difficult such as embankments. Also used to enhance sucrose content in sugarcane.

Uses

Mefluidide is a plant growth regulator that suppresses annual bluegrass seedheads on creeping bentgrass greens. An antiparasitic agent.

Uses

Plant growth regulator; herbicide.

Definition

ChEBI: Mefluidide is a sulfonamide.

Agricultural Uses

Herbicide; plant growth regulator: Not approved for use in EU countries . Mefluidide is used to control ornamental and non-ornamental woody plants, ground cover, hedges, trees, turfgrass and broadleaf weeds. Both the diethanolamine and potassium salts are actively used in the U.S.

Trade name

EMmHgK®; MBR 12325®; MBR 12325®; METHAFLUORIDAMID®; S 15733®; VEL 3973®; VISTAR® Herbicide

Potential Exposure

Mefluidide is an anilide herbicide and plant growth regulator used to control ornamental and nonornamental woody plants, ground cover, hedges, trees, turfgrass, and broadleaf weeds. Both the diethanolamine and potassium salts are actively used in the United States Not refistered for use in the EU.

Environmental Fate

Soil. Rapidly degrades in soil forming 5-amino-2,4-dimethyltrifluoromethane sulfone anilide as the major metabolite (half-life <1 week) (Hartley and Kidd, 1987).
