Problem to be Solved It is intended to provide an industrially preferable fluoroalkylating agent and use thereof. Solution The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R^(1 )is a C1 to C8 fluoroalkyl group; R^(2 )and R^(3 )are each independently a C1 to C12 alkyl group or the like; Y^(1 )to Y^(4 )are each independently a hydrogen atom, a halogen atom, or the like; and X^() is a monovalent anion. A compound of the general formula (3): R^(4)SR^(1 )having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R^(4)SZ wherein R^(4 )is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).

Provided is an agrochemical composition for foliage treatment, which does not cause phytotoxicity to a cultivated crop due to adhesion thereto when foliage treatment of an upland field is performed with pyroxasulfone, but has a high level of safety and an herbicidal effect on a broad spectrum of weeds. The agrochemical composition for foliage treatment comprises pyroxasulfone and a masking material that masks the pyroxasulfone, wherein the pyroxasulfone is microencapsulated in or coated with the masking material such that phytotoxicity to a cultivated crop due to adhesion thereto when foliage spraying is performed is avoided.
