DESCRIPTION:

BRIEF SUMMARY
This application is a 371 of PCT/UP93/00273, filed Mar. 3, 1993.


FIELD OF THE INVENTION

The present invention relates to an N-sulfonyl carboxylic amide derivative including an N-containing 6-membered aromatic ring, or the salt of the same as well as a biocide containing the same as an active ingredient.


BACKGROUND OF THE INVENTION

Heretofore, some compounds possessing chemical structures similar to that of the N-sulfonyl carboxylic amide derivative according to the present invention have been known in Japanese Patent Application First Publication No. Hei 2-282371. The document discloses that such compounds possess effects as a plant growth modifier or as a herbicide.


DISCLOSURE OF THE INVENTION

In agricultural production, blight caused by plant pathogenic fungi belonging to Oomycetes such as downy mildew, late blight, or the like occurs on many plants and this is one of the most difficult blights to control. For this reason, it is desired that an improved control agent be developed.
The present inventors have synthesized various N-sulfonyl carboxylic amide derivatives including N-containing 6-membered aromatic rings and have carried out extensive research in connection with their effects on the physiological activities of fungi. As a result, we have found that the N-sulfonyl carboxylic amide derivatives according to the present invention exhibit anti-fungal activity. The compounds which are active ingredients of a biocide according to the present invention are novel and can control various weeds occurring in paddy fields and plowed fields.
The present invention provides a biocide containing an N-sulfonyl carboxylic amide derivative including an N-containing 6-membered aromatic ring represented by formula [I]: ##STR2## wherein R.sup.1 represents an alkyl group {optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen atom, a cycloalkyl group, an R.sup.7 O group [wherein R.sup.7 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, a phenyl group (optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, a haloalkyl group, and an alkoxycarbonyl group)], an R.sup.7 S(O).sub.n group (wherein R.sup.7 has the same meaning as defined above, n is an integer from 0 to 2), an R.sup.7 R.sup.8 N group [wherein R.sup.7 has the same meaning as defined above, R.sup.8 represents an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, an alkenyloxy group, alkynyloxy group, or a phenyl group (optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, a haloalkyl group, and an alkoxycarbonyl group)], a trimethylsilyl group, a cyano group, an oxiranyl group, an R.sup.8 CO group (wherein R.sup. 8 has the same meaning as defined above), and an R.sup.8 C.dbd.NOR.sup.9 group (wherein R.sup.8 has the same meaning as defined above, and R.sup.9 represents an alkyl group, an alkenyl group, or an alkynyl group)}, an alkenyl group {optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen atom, a phenyl group (optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, a haloalkyl group, and an alkoxycarbonyl group)], a cycloalkyl group, an R.sup.7 O group (wherein R.sup.7 has the same meaning as defined above), an R.sup.7 S(O)n group (wherein R.sup.7 and n have the same meanings as defined above), an R.sup.7 R.sup.8 N group (wherein R.sup.7 and R.sup.8 have the same meanings as defined above), a trimethylsilyl group, a cyano group, an R.sup.8 CO group (wherein R.sup.8 has the same meaning as defined above), and an R.sup.8 C=NOR.sup.9 group (wherein R.sup.8 and R.sup.9 have the same meanings as defined above)}, an alkynyl group, a cycloalkyl group {optionally having mono-substituent or poly-substituents selected from the group consisting of a halogen
