FIELD: chemistry.

SUBSTANCE: invention relates to a compound of formula (I) and an agriculturally acceptable salt thereof, where R¹ is C₁-C₂ haloalkyl; L¹ is a direct bond; L² is a direct bond; A is phenyl or pyridyl; and said phenyl or pyridyl is optionally substituted with one or more identical or different groups R^A; R^A is selected from the group consisting of hydrogen, halogen, cyano, amino, hydroxy, C₁-C₆alkyl, C₃-C₈cycloalkyl, C₁-C₆haloalkyl, C₁-C₆hydroxyalkyl, C₃-C₈halocycloalkyl, C₁-C₆alkoxy and C₁-C₆haloalkoxy; R^4b is independently selected from the group consisting of hydrogen, C₁-C₆alkyl, C₁-C₆haloalkyl, C₁-C₆alkoxy and C₁-C₆haloalkoxy; R^2d, R^3d, R^2f and R^3f are independently selected from the group consisting of hydrogen, halogen, C₁-C₄alkyl, C₁-C₄haloalkyl, C₁-C₄alkoxy and C₁-C₄haloalkoxy; W¹ is O; Q is O, S(=O)_0-2, S(=O)_0-1(=NR^4b), NR^4b, -N=S(=NR^8a)(R^8b)-; -N=S(=O)_0-1(R^8c)-; values of radical R¹⁰ are defined in cl. 1 of the claims. Invention also relates to methods of producing a compound of formula (I) and a composition based on the compound of formula (I).

EFFECT: novel compounds of formula (I) are obtained, which can be used in agriculture as agents for controlling or preventing infection of plants with phytopathogenic microorganisms.
