Iminopropene compound and use thereof

TECHNICAL FIELD

The present invention relates to an iminopropene compound and pesticidal use thereof.

BACKGROUND ART

Heretofore, the development of pesticides has been carried out and many compounds which are effective for controlling pest have been found. However, their activity is not always sufficient. Accordingly, there are further demands for developing novel compounds having pest-controlling activity.

DISCLOSURE OF INVENTION

The present invention is intended to provide a compound having superior pest-controlling activity.

The present inventor has intensively studied in order to find a compound having superior pest-controlling activity and, as a result, has found that an iminopropene compound represented by the formula (I) has superior pest-controlling activity. Thus, the present invention has been completed.

That is, the present invention provides as follows:

An iminopropene compound given by the formula (I) or a salt thereof:
