The present invention relates to microbicides for agricultural or horticultural use containing sulfonamide derivative of, for example, a formula (I):
or a salt thereof,
[wherein A1 is (1) an aryl group which may be substituted or (2) a heterocyclic group which may be substituted, X1 is (1) a chemical bond, (2) a methylene group which may be substituted, or (3) a vinylene group which may be substituted, B1 is a five-membered heterocyclic group comprising nitrogen or sulfur atoms as the ring-constructing atoms except for carbon atoms and may be substituted or a condensed heterocyclic group which may be substituted, Z1 is (1) a hydrocarbon group which may be substituted, (2) an acyl group which may be substituted, (3) formyl group, (4) an amino group which may be substituted, (5) a group represented by -N=CR1R2 (wherein each of R1 and R2 is a hydrogen atom or a hydrocarbon group which may be substituted), (6) a cyclic amino group, (7) a group represented by -OR3 (wherein R3 is a hydrogen atom, a hydrocarbon group which may be substituted, an acyl group which may be substituted, formyl group or an alkylsulfonyl group which may be substituted) or (8) -S(O)nR4 (wherein n stands for an integer from 0 to 2, R4 stands for a hydrogen atom or a hydrocarbon group which may be substituted). The said compounds or the salts thereof are sulfonamide derivatives with microbicidal action, are useful as excellent microbicides for agricultural or horticultural use, because they are safe, and they have little influence on human beings, farm animals, natural enemies, or the environment, and exert excellent control effects even on resistant microbes.
本发明涉及含有例如式(I)的磺酰胺衍生物的农业或园艺用杀微生物剂:
或其盐、
[其中 A1 是(1)可被取代的芳基,或(2)可被取代的杂环基,X1 是(1)化学键,(2)可被取代的亚甲基,或(3)可被取代的亚乙烯基、Z1 是 (1) 可被取代的烃基,(2) 可被取代的酰基,(3) 甲酰基、(4) 可被取代的氨基; (5) 由 -N=CR1R2 表示的基团(其中 R1 和 R2 各为氢原子或可被取代的烃基); (6) 环状氨基; (7) 由 -OR3 表示的基团(其中 R3 为氢原子、(8) -S(O)nR4(其中 n 代表 0 至 2 的整数,R4 代表氢原子或可被取代的烃基)。上述化合物或其盐类是具有杀微生物作用的磺酰胺衍生物,是农业或园艺用途的优良杀微生物剂,因为它们安全,对人类、农场动物、天敌或环境的影响很小,甚至对抗性微生物也有很好的控制效果。
