摘要:
The substituted thiophene derivative of the invention which is represented by the general formula (1) has a broad disease spectrum for a pathogenic fungus of various crops, exhibits an excellent controlling effect on disease such as gray mold, powdery mildew and rust in particular, and is also effective for a resistant fungus of conventional fungicides which has become a serious problem, and consequently is useful for an agricultural and horticultural fungicide. ##STR1##
摘要:
A substituted anilide derivative represented by the formula (2): ##STR1## wherein A and B are methyl, and X is a hydrogen atom. The substituted anilide can be used to prepare a substituted carboxanilide derivative that 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 activity against strains that are resistant to conventional chemicals, is safe for crops, and thus is useful as a plant disease control agent.
摘要:
A substituted carboxanilide derivative represented by the formula (1): ##STR1## wherein A 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 effects 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 control agent.
摘要:
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.
摘要:
The invention provides a plant disease control composition including active ingredients of (RS)-N-[2-(1,3-dimethylbutyl)thiophene-3-yl]-1-methyl-3-trifluoromethyl-1H-pyrazole-4-carboxamide (common name: penthiopyrad) and at least one fungicidal compound other than penthiopyrad, and a plant disease prevention method wherein such a compound is applied to plant seeds or soil. According to the invention, a composition and a prevention method are provided which demonstrate a prevention effect against plural types of disease pathogenic microbes, and also demonstrate a preventing effect to currently emerging resistant pathogenic microbes, when applied to plant seed or soil.
