A novel substituted thiophene derivatives represented by the formula (1) in the invention: ##STR1## 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.
本发明提供一种用公式(1)表示的新型替代噻吩衍生物:##STR1##其中R是直链或支链烷基,具有3-12个碳原子,直链或支链卤代烷基,具有3-12个碳原子,直链或支链烯基,具有3-10个碳原子,直链或支链卤代烯基,具有3-10个碳原子,或有3-10个碳原子的环烷基,该环烷基未取代或被取代为具有1-4个碳原子的烷基,R和--NHCOAr相邻,Ar是杂环基;这些衍生物对各种植物病害如灰霉病、白粉病、枯萎病和锈病具有优异的控制活性,并且由于对灰霉菌具有杰出的残留效果和对赤霉病菌具有优异的效果,因此可用作植物病害防治剂。
