AR115871A1 - METHOD FOR CONTROLLING SOYBEAN ROY FUNGUS THAT HAS RESISTANCE TO SITE INHIBITOR Qₒ - Google Patents

Abstract

Claim 1: A method for controlling a soybean rust fungus that has an amino acid substitution of F129L in the mitochondrial cytochrome b protein, characterized in that it comprises the application of an effective amount of a compound represented by the formula (1) , [where Q represents a group represented by the compounds Q1 or Q2 of the group of formulas (2) (in the formulas, · represents a binding site with the benzene ring), R¹ represents a group of hydrocarbon chain C₁₋₃, n is 1, 2, 3, 4 or 5, when n is 2, 3, 4 or 5, a plural of R² may be the same or different from each other, R² represents a C₁₋₆ hydrocarbon chain group optionally substituted with one or plus substituents selected from group A, a C₃₋₆ cycloalkyl group optionally substituted with one or more substituents selected from group B, OR³, S (O) ₘR⁵, OS (O) ₂R⁵, C (O) R³, C (O) OR³ , NR³R⁴, C (O) NR³R⁴, S (O) ₂NR³R⁴, NR⁴C (O) R³, NR⁴C (O) OR⁵, NR⁴S (O) ₂R⁵, CR⁴ = N-OR³, a cyano group, a nitro group or a halogen atom, when R² is attached at position 2, R¹ and R² combine with each other with the carbon atom to which they are attached and the carbon atom at position 1, to form a carbocycle of five, six, or seven members {the carbocycle can be optionally substituted with one or more R⁶ and when a plural of R⁶ is present, the plural of R⁶ can be the same or different from each other}, when two R² are adjacent to each other, two of the R² can be combined together with the carbon atom to which they are attached to form a five-, six- or seven-membered aromatic or partially unsaturated ring {the aromatic or partially unsaturated ring may be optionally substituted with one or more R⁷ and when a plural of R⁷ is present, a plural of R⁷ may be the same or different from each other and furthermore the partially unsaturated or aromatic ring may be a carbocycle or a heterocycle and the ring atoms in the heterocycle may contain, in addition to the carbon atoms, one, two or three heteroatoms selected from the group consisting of N, O and S}, R³ and R⁴ are the same or different from each other and represent a C₁₋₆ hydrocarbon chain group optionally substituted with one or more substituents selected from group A, a cycloalkyl group C₃₋₆ optionally substituted with one or more substituents selected from group B or a hydrogen atom, R⁵ represents a C₁₋₆ hydrocarbon chain group optionally substituted with one or more substituents selected from group A or an optionally substituted C₃₋₆ cycloalkyl group with one or more substituents selected from group B, R⁶ and R⁷ are the same or different from each other and represent a C₁₋₆ hydrocarbon chain group optionally substituted with one or more substituents selected from group A, a C₃₋₆ cycloalkyl group optionally substituted with one or more substituents selected from group B, a halogen atom, a cyano group, or a nitro group, Group A: a group selected from the group that consists of a halogen atom, a C₃₋₆ cycloalkyl group, a C₁₋₄ alkoxy group, a C₁₋₄ alkyl-thio group {the C₃₋₆ cycloalkyl group, the C₁₋₄ alkoxy group and the C₁₋ alkyl group ₄-thio may each be optionally substituted with one or more substituents selected from the group consisting of a halogen atom and a cyano group}, a cyano group, a nitro group, and a hydroxy group, Group B: a group consisting of a halogen atom, a C₁₋₆ hydrocarbon chain group, a C₃₋₆ cycloalkyl group, a C₁₋₄ alkoxy group, a C₁₋₄ alkyl-thio group {the C₁₋₆ hydrocarbon chain group, the C₃ cycloalkyl group ₋₆, the C₁₋₄ alkoxy group and the C₁₋₄ alkylthio group may each be optionally substituted with one or more substituents selected from the group consisting of a halogen atom and a cyano group}, a cyano group, a nitro group and a hydroxy group] to the soybean or the soil where the soybean grows. Claim 5: Use of the compound represented by formula (1) described in any of claims 1 to 4, characterized in that it is to control a soybean rust fungus that had an amino acid substitution of F129L in the cytochrome b protein mitochondrial.
