FIELD: agriculture; chemistry.

SUBSTANCE: group of inventions relates to agricultural chemicals and includes a compound of the formula (1), a compound of the formula (2), which is an intermediate for obtaining the compound of the formula (1), an agricultural fungicidal composition and methods for the prevention or treatment of a fungal plant disease. In the formula (1), R1 is C1-C6 alkyl group optionally substituted with A, C1-C6 haloalkyl group or RaRbN- (where Ra and Rb, each independently, is a hydrogen atom, C1-C6 alkyl group optionally substituted with B, C1-C6 haloalkyl group or C3-C8 cycloalkyl group, or Ra and Rb, together with a nitrogen atom, to which they are bound, form an aziridinyl group, azetidinyl group, pyrrolidinyl group, piperidinyl group, homopiperidinyl group or azocanyl group); R2 is a hydrogen atom, halogen atom, C1-C6 alkyl group optionally substituted with A, C1-C6 haloalkyl group, C2-C6 alkynyl group optionally substituted with A, C1-C6 alkoxy group optionally substituted with A or Rx1C(=O)- (where Rx1 is a hydrogen atom, C1-C6 alkyl group optionally substituted with B, C1-C6 haloalkyl group, C3-C8 cycloalkyl group, C1-C6 alkoxy group, C1-C6 haloalkoxy group, C3-C8 cycloalkoxy group or RaRbN-); Het is a pyridyl group, thienyl group, pyrrolyl group, pyrazolyl group, imidazolyl group, triazolyl group, tetrazolyl group, oxazolyl group, or 3-6-element ring group containing from 1 to 2 oxygen atoms, and Het can be substituted with substituents specified in the claims; R3 is a cyano group, nitro group, halogen atom, C1-C6 alkyl group optionally substituted with C, C1-C6 haloalkyl group, C1-C6 alkoxy group optionally substituted with C, RaRbN-, Rx1C(=O)-, Rx2C(=O)N(Rx3)- (where Rx2 and Rx3 are as indicated in the claims); Y is a phenyl group substituted with R4 in an ortho position and additionally optionally substituted with 0-4 of R5; R4 is a cyano group, nitro group, halogen atom, C1-C6 alkyl group optionally substituted with C, C1-C6 haloalkyl group or C1-C6 alkoxyl group optionally substituted with C; R5 is a hydroxy group, cyano group, halogen atom, C1-C6 alkyl group optionally substituted with C, C1-C6 alkoxy group optionally substituted with C, C2-C6 alkenyloxy group optionally substituted with C, C3-C6 alkynyloxy group optionally substituted with C, RaRbN-, Rc-L- (where Rc is C1-C6 alkyl group or C1-C6 haloalkyl group, and L is S, SO or SO₂) or Rx1C(=O)O-; X is an oxygen atom or a sulfur atom; a bond containing a dashed line is a double or single bond; and substituents are as specified in the claims.

EFFECT: compound of the formula (1) with fungicidal activity.
