DESCRIPTION:
BRIEF SUMMARY
This application claims priority under 35 U.S.C. .sctn.365(a) to International Patent Application PCT/JP91/01649 filed Nov. 29, 1991, and from thence under 35 U.S.C. .sctn.119 to Japanese patent application no. 330168/1990 filed Nov. 30, 1990.
TECHNICAL FIELD
The present invention relates to novel alkanoic acid amide derivatives and their salts, and herbicidal compositions containing them, which are useful for application to paddy fields, upland fields and non-agricultural fields.
BACKGROUND ART
In recent years, many herbicides have been developed, and have contributed to the improvement of productivity and to energy saving for agricultural works. However, since many of these herbicides work specifically on respective crop plants and weeds, it is necessary to selectively use depending on the individual types of cropplants and places to be applied, so as to be most effective. Therefore, it is always an important subject matter in this field to develop a novel compound having a herbicidal effect.
An object of the present invention is to provide a novel herbicidal composition containing a compound having a chemical structure different from those of conventional herbicides as an effective ingredient, which can be many-sidedly used for the cultivation of various crop plants.
As a result of the study for achieving the abovementioned object, the present inventors have discovered that a sort of an alkanoic acid amide derivative having a pyrimidine ring or a triazine ring or its salt is effective for killing various weeds, and is safe to crop plants. The present invention has been achieved on the basis of this discovery.
DISCLOSURE OF THE INVENTION
The present invention relates to an alkanoic acid amide derivative of the following formula (I) and its salt: ##STR2## wherein R.sup.1 is a hydrogen atom, a hydroxy group, a C.sub.1 -C.sub.8 alkyl group (which may be substituted with a C.sub.1 -C.sub.8 alkoxy group, a benzyloxy group, a C.sub.1 -C.sub.8 alkoxy C.sub.1 -C.sub.8 alkoxy group, a C.sub.1 -C.sub.8 alkoxycarbonyl group, a C.sub.1 -C.sub.3 alkylthio group or a phenyl group), a C.sub.2 -C.sub.6 alkenyl group, a C.sub.2 -C.sub.6 alkynyl group, a C.sub.1 -C.sub.8 alkoxy group, a benzyloxy group, a C.sub.2 -C.sub.6 alkenyloxy group, or a C.sub.2 -C.sub.6 alkynyloxy group; R.sup.2 is a hydroxy group, a C.sub.1 -C.sub.8 alkoxy group, a benzyloxy group, a C.sub.2 -C.sub.6 alkenyloxy group, a cyano group, a phenyl group (which may be substituted with a C.sub.1 -C.sub.8 alkyl group, a trifluoromethyl group, a halogen atom or a nitro group), an amino group, a C.sub.1 -C.sub.8 alkylsulfonylamino group or a group of -SO.sub.2 R.sup.5 (R.sup.5 is a C.sub.1 -C.sub.8 alkyl group (which may be substituted with a C.sub.1 -C.sub.8 alkoxy group or a halogen atom), a C.sub.2 -C.sub.6 alkenyl group, a C3-C.sub.8 cycloalkyl group, a C.sub.1 -C.sub.8 alkylamino group, a di-C.sub.1 -C.sub.8 alkylamino group, a 1-pyrrolidinyl group or an anilino group); R.sup.3 is a hydrogen atom, a C.sub.1 -C.sub.8 alkyl group (which may be substituted with a hydroxy group, a C.sub.1 -C.sub.8 alkoxy group, a phenoxy group, a C.sub.1 -C.sub.8 alkylthio group, a phenylthio group, a trimethylsilyl group, a C.sub.3 -C.sub.8 cycloalkyl group, a phenyl group or a di-C.sub.1 -C.sub.8 alkylamino group), a C.sub.2 -C.sub.6 alkenyl group (which may be substituted with a halogen atom), a C.sub.2 -C.sub.6 alkynyl group, a C.sub.3 -C.sub.8 cycloalkyl group (which may be substituted with a C.sub.1 -C.sub.3 alkyl group), a C.sub.3 -C.sub.6 cycloalkenyl group, a phenyl group (which may be substituted with a C.sub.1 -C.sub.8 alkyl group or a halogen atom), a tetrahydrothienyl group or a tetrahydrofuryl group; R.sup.4 is a hydrogen atom or a C.sub.1 -C.sub.8 alkyl group; X and Y may be the same or different, and are a hydroxy group, a halogen atom, a C.sub.1 -C.sub.8 alkyl group, a C.sub.1 -C.sub.8 haloalkyl group, a C.sub.1 C.sub.8 alkoxy C.sub.1 -C.sub.8 alkyl group, a C.sub.1 -C.sub.8 alkoxy group, a phenoxy group (which may be substituted with a C.sub.1 -C
