摘要:
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 .
摘要:
A substituted carboxanilide derivative provided by the invention and represented by the formula (1): wherein A is is a hydrogen atom or methyl, B is a methyl or ethyl, and Het is 1-methyl-3-substituted-4-pyrazolyl or 2-methyl-4-substituted-5-triazoyl group, exhibits a disease control effect against Botrytis cinerea , Powdery mildew, Pyricularia oryzae of rice plant and other various plant diseases, is excellent in residual effect, has also activity against resistant strain for conventional chemicals, particularly exerts control effect against Botrytis cinerea at a lower dosage as compared with a prior art, is also safe for crops, and thus is useful as a plant disease control agent.
