Description

Pest control composition containing pyridone compound and quinoline compound, pest control method, and novel quinoline compound

The present invention relates to a pest control composition containing a pyridone compound and one or more quinoline compounds as active ingredients, and a novel quinoline compound.

In agricultural and horticultural scenes, conventionally, in order to control pests such as pests, pathogens, and weeds, it is a common practice to use pesticides suitable for pest control.
Furthermore, for the purpose of controlling various pests at the same time, a mixed composition containing a plurality of active ingredients has been used.

On the other hand, the use of drugs over many years has led to the emergence of resistant pests and resistant bacteria that have acquired resistance to drugs, making it difficult to control with conventional drugs, so new pest control agents are constantly needed. It is said that. Moreover, using the mixed agent which combined the active ingredient which has a different action mechanism is performed in order to reduce the generation | occurrence | production risk of a resistant pest and a resistant microbe.

By the way, for 1,3,5,6-substituted-2-pyridone compounds, for example, 1,3,5,6-substituted-2 having an aryl group or heteroaryl group at the 3-position as a GABA alpha-2 / 3 ligand. -Pyridone compounds have been disclosed (see eg WO 98/55480). In addition, 1,3,5,6-substituted-2-pyridone compounds having a carboxyl group at the 3-position have been disclosed as therapeutic agents for bacterial infections (see, for example, European Patent No. 0308020). However, the uses of the compounds described in WO 98/55480 and EP 0308020 are all related to medicines and are different from the technical field to which the pest control composition according to the present invention belongs. To do.

Regarding the quinoline compounds represented by the formula (2a) or the formula (2b), Patent Documents 3 and 4 disclose that rice blasts of rice blast (Pyricularia oryzae) and tomato, cucumber and kidney beans are gray as quinoline compounds as fungicides. It has been disclosed that a disease control such as fungus disease (Botrytis cinerea), cucumber vine split disease (Fusarium oxysporum) and the like can be controlled by treatment methods such as foliage spraying, soil treatment, seed treatment, and the like. Patent Documents 5 and 6 disclose mixing of the quinoline compound represented by the formula (2a) or the formula (2b) with a certain fungicide, but mixing with the pyridone compound of the present invention. Is not disclosed.

However, in the mixed composition containing a plurality of active ingredients as described above, the effect on pests may be lower than when used alone, so it contains new active ingredients and is sufficient for pests. Therefore, a mixed composition that exhibits an excellent control effect is desired.
An object of the present invention is to provide a pest control composition having a useful control effect including a combination of a novel pyridone compound or a salt thereof and a quinoline compound, a method of using the same, and a novel quinoline compound having a useful control effect Is to provide.

In order to solve the above problems, the present inventors have conducted extensive studies on the 1,3,5,6-substituted-2-pyridone compound group and the 1,5,6-substituted-2-pyridone compound group. A pest control composition comprising, as active ingredients, a compound group having an aryl group or heteroaryl group having a substituent at the ortho position with respect to the 6-position in the 2-pyridone skeleton, and one or more quinoline compounds; The present inventors have found that a novel quinoline compound exhibits excellent pest control activity and has completed the present invention.
