Documented Uses

• Used as a plant growth regulator and herbicide; [Merck Index] Used as an anilide post-emergence plant growth regulator to suppress seed heads and fruiting and to slow plant growth to reduce maintenance; Registered for non-crop land (i.e. industrial, roadside, and public areas) and residential turf; Multiple products also contain additional plant growth regulators or herbicides (i.e. Paclobutrazol and Imazapyr); [Reference #1] Used to accelerate sugar cane ripening; [HSDB]
• No registered food/feed uses and no food tolerances in the US; [Reference #1]
• Mefluidide is a plant growth regulator that is applied postemergence when needed, and is a member of the anilide class of compounds. It is used to suppress seed heads and fruiting, as well as retarding growth to reduce mowing and trimming. It is also registered for growth control of low maintenance turf on rights-of-ways, airports, public and industrial sites. Mefluidide products can also be used on residential lawns. There are no registered food/feed uses, and no food tolerances exist for mefluidide.
• Plant growth regulator; herbicide.
• Plant growth regulator, used for turf and ornamentals.
• Mefluidide can be synthesized by reaction of 2,4-dimethyl-5-nitroaniline with acetyl chloride, reduction of the nitro group, and treatment of the resulting product with trifluoromethylsulfonyl chloride.
