Claims8
A composition for controlling a plant disease, comprising:
- a compound represented by formula (I);
- and
- at least one sterol biosynthetic enzyme inhibitor selected from the group consisting of prothioconazole and mefentrifluconazole,
- where
- E represents (i) an ethynyl group substituted with a C1-C4 alkyl group, (ii) a R2ON—C(CH3)—, or (iii) a phenyl group optionally substituted with a halogen atom;
- R1 represents a methyl group or a chlorine atom;
- R2 represents a C1-C4 alkyl group optionally substituted with a substituent selected from the group consisting of a phenyl group {wherein said phenyl group is optionally substituted with a methyl group} and a cyclopropyl group;
- A represents a CH or a nitrogen atom;
- and
- L represents a CH2 or an oxygen atom;
- wherein when A represents a nitrogen atom, then L does not represent an oxygen atom,
- wherein the weight ratio of the compound represented by formula (I) to the sterol biosynthetic enzyme inhibitor is within the range of 1:0.01 to 1:100.
