Abstract

A composition for controlling a plant disease is provided, containing a tetrazolinone compound represented by formula (1), wherein X 1 represents a halogen atom, a C1-C6 alkyl group, or a C1-C6 alkoxy group, and X 2 represents a C1-C3 alkyl group, a C3-C4 cycloalkyl group, a halogen atom, or a C1-C3 alkoxy group, and a carboxamide compound represented by formula (2). A method for controlling a plant disease is also provided, containing a step of applying an effective amount of the tetrazolinone compound represented by formula (1) and an effective amount of the carboxamide compound represented by formula (2) to a plant or soil for cultivating the plant. Both the composition and the method have excellent control efficacies against plant diseases.

First claim

The invention claimed is:

1. A composition for controlling a plant disease comprising a tetrazolinone compound represented by formula (1):

wherein
X 1 represents a chlorine atom, and
X 2 represents a methyl group, and

a carboxamide compound represented by formula (2):

2. The composition for controlling a plant according to claim 1 , wherein a weight ratio of the tetrazolinone compound to the carboxamide compound is 1:0.0125 to 1:500.

3. A method for controlling a plant disease, comprising applying an effective amount of a tetrazolinone compound represented by formula (1):

wherein
X 1 represents a chlorine atom, and
X 2 represents a methyl group, and

an effective amount of a carboxamide compound represented by formula (2):

to a plant or soil for cultivating the plant.

4. A method for controlling a plant disease, comprising applying an effective amount of a tetrazolinone compound represented by formula (1):

wherein
X 1 represents a chlorine atom, and
X 2 represents a methyl group, and

an effective amount of a carboxamide compound represented by formula (2):

to a seed.
