An object of the present invention is to provide compounds represented by the formula (1) or salts thereof that are effective as agricultural and horticultural fungicides.

Compounds having a nitrogen-containing unsaturated six-membered ring and agricultural and horticultural fungicides containing the same as active ingredients

A compound of formula (1) or a salt thereof, which is effective as a parasitic pest control agent, is provided. In the formula, R1 represents, for example an optionally substituted C1-C6 alkyl group, a C1-C6 haloalkyl group, R2 represents, for example a halogen atom, an optionally substituted C1-C6 alkyl group, an optionally substituted C1-C6 alkoxy group, R3 represents, for example a hydrogen atom, a halogen atom, an optionally substituted C1-C6 alkyl group, n represents an integer of 0 to 5, X represents an oxygen atom or sulfur atom, Y represents, for example phenyl substituted at an ortho position, pyridyl, and the bond with a broken line represents a double bond or a single bond. 

Parasitic pest control agents comprising pyridone compounds as active ingredients and methods for using the same

Pyridine compounds of Formula (1) are provided: wherein R1, R2, X, Y and Het are defined. The pyridine compounds can be used to treat or prevent plant diseases.

Pyridone compounds and agricultural and horticultural fungicides containing the same as active ingredients

Pyridone compounds of formula (1) and salts thereof: wherein R1, R2, R3, X, Y1, Y2, Y3 and n are defined. The pyridone compounds can control plant diseases.

Pyridone compounds and agricultural and horticultural fungicides comprising the same as active ingredients

Provided are a pyridone compound represented by Formula (1): wherein

An object of the invention is to provide compounds of formula (1) or salts thereof which are effective as agricultural and horticultural fungicides. In the formula, R1 represents, for example, a hydroxy group or a cyano group, R2, R3 and R4 are independent of one another and each represent, for example, a hydrogen atom or a halogen atom, R5 represents, for example, a hydrogen atom or a halogen atom, X represents an oxygen atom or a sulfur atom, Y represents, for example, a phenyl group or a pyridyl group, and the bond including the broken line represents a double bond or a single bond.

A pyridone compound represented by Formula (1): wherein R1, R2, X, Y and Z are defined. The pyridone compound can control plant diseases.

A compound represented by Formula (1) or a salt thereof is provided. R1 represents a C1-C6 alkyl group optionally substituted, a C1-C6 haloalkyl group or the like, R2 represents a halogen atom, a C1-C6 alkyl group optionally substituted, a C1-C6 alkyloxy group optionally substituted or the like, R3 represents a hydrogen atom, a halgenatom, C1-C6 alkyl group optionally substituted or the like, n represents an integer of 0 to 5, X represents an oxygen atom or a sulfur atom, Y represents a phenyl group or a pyridyl group that is substituted with substituent at an ortho position, and the bond with a broken line indicates a double bond or a single bond.
