ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a 5,6-dihydrouracil compound, a herbicidal composition comprising it as an active ingredient, a process for producing it and an intermediate compound for producing it.
BACKGROUND ARTS
At the present time, numerous herbicides are commercially available and they are used. There are, however, many species of weeds to be controlled and their growth extends over a long time. For this reason, requested are herbicides with higher herbicidal activity, wide herbicidal spectrum, and without causing a phytotoxicity problem to crops.
Japanese laid-open patent publication No. Hei06-092943 and U.S. Pat. No. 4,927,451 specification describe a sort of 5,6-dihydrouracil compounds below having a herbicidal activity.
However, the compounds described thereof do not always have sufficient character.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a compound having excellent character as a herbicide.
The present inventors intensively studied to find out compounds having excellent character for herbicides. As a result, they have found that the 5,6-dihydrouracil compounds given by the formula [I] below have excellent character for herbicides, and completed the present invention. Namely, the present invention provides the 5,6-dihydrouracil compound [hereinafter, referred to as the present compound(s)] given by the formula [I]:
