A novel substituted thiophene derivatives represented by the formula (1) in the invention:
wherein R is a straight or branched alkyl group having 3-12 carbon atoms, straight or branched halogenoalkyl group having 3-12 carbon atoms, straight or branched alkenyl group having 3-10 carbon atoms, straight or branched halogenoalkenyl group having 3-10 carbon atoms, or cycloalkyl group having 3-10 carbon atoms, the cycloalkyl group being unsubstituted or substituted with an alkyl group having 1-4 carbon atoms, R and -NHCOAr are adjacent to each other, and Ar is a heterocyclic group;
have excellent control activity on various plant disease such as Gray mold, Powdery mildew, Blast and Rust, and are useful as a plant disease control agent due to outstanding residual effect on Botrytis cinerea and excellent effect on Gibberella zeae.
一种由本发明中式(1)代表的新型取代噻吩衍生物:
其中 R 是具有 3-12 个碳原子的直链或支链烷基、具有 3-12 个碳原子的直链或支链卤代烷基、具有 3-10 个碳原子的直链或支链烯基、具有 3-10 个碳原子的直链或支链卤代烯基或具有 3-10 个碳原子的环烷基,环烷基未被取代或被具有 1-4 个碳原子的烷基取代,R 和 -NHCOAr 相邻,Ar 是杂环基团;
对灰霉病、白粉病、疫病和锈病等多种植物病害具有优异的防治活性,由于对灰霉病菌(Botrytis cinerea)具有突出的残留效果,对赤霉病菌(Gibberella zeae)具有优异的效果,因此可用作植物病害防治剂。
