Uses and applications

What the substance is used for, by industry and function

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.

How it is made

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.

Preparation: T.L. Fridinger, Germany patent 2406475, idem, United States of America patent 3894073 (1974, 1975 to 3M).
