摘要:
A 1,2,3-thiadiazole derivative represented by general formula (I) or a salt thereof: wherein R 1 is H, (halo) C 1 -C 4 alkyl, 5- or 6-membered heterocycle containing 1 to 3 same or different O, N or S or the like, A is a group of the following formulas: wherein R 2 and R 3 are H, halogen, cyano, formyl, alkylthio, alkoxycarbonyl, substituted or unsubstituted phenyl, or the like, or R 2 and R 3 , taken conjointly, may form a 3- to 7-membered ring including a C 2 -C 6 alkylene group which may be intercepted by -O-, -S(O) n - (n is 0-2), -CO- or -NR 8 - (R 8 is H, halogen or the like), B is cyano or an unsubstituted or substituted 5- or 6-membered heterocycle containing 1-3 hetero atoms selected from O, N and S, and m is 0-4; salts thereof; an agrohorticultural disease controller containing said derivative or salt; and method for using said disease controller.
摘要:
1,2,3-Thiadiazole derivatives of general formula (I) and salts thereof, disease controlling agents containing the derivatives or salts as the active ingredients, and a method for the use of the same, wherein R1 is H, C¿1?-C4 (halo)alkyl, a 5- or 6-membered heterocyclic group containing 1 to 3 heteroatoms which may be the same or different from each other and are selected from among O, N and S, or the like; A is (a), (b), (c), (d) (wherein R?2 and R3¿ are each H, halogeno, cyano, formyl, alkylthio, alkoxycarbonyl, substituted or unsubstituted phenyl or the like, or alternatively R?2 and R3¿ may be united to form a C¿2?-C6 alkylene which is optionally interrupted by -O-, -S(O)n- (wherein n is 0 to 2), -CO- or -NR?8¿- (wherein R8 is H, halogeno or the like), thus forming a 3- to 7-membered ring); B is cyano, an optionally substituted 5- or 6-membered heteroxyclic group containing 1 to 3 heteroatoms selected from among O, N and S, or the like; and m is 0 to 4.
