ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to pyridazinone derivatives and the use of the said pyridazinone.
The object of the present invention is to provide compounds having excellent herbicidal activity.
SUMMARY OF THE INVENTION
The present inventor has intensely studied to seek out compounds that have excellent herbicidal activity, as a result, and has found that the pyridazinone derivatives encompassed by Chemical Formula 3 below, possess an excellent herbicidal activity, and arrived at the present invention. Accordingly, the present invention provides pyridazinone derivatives (hereinafter, the present invention compound) encompassed by the formula:
