A 3(2H)-pyridazinone derivative of the general formula (I): ##STR1## wherein R is a straight or branched C.sub.2 -C.sub.6 alkyl, A is a straight or branched C.sub.1 -C.sub.6 alkyl or a halogen atom, X is --O-- or --S--, R.sup.1 and R.sup.2 are each independently hydrogen atom or C.sub.1 -C.sub.3 alkyl, B is --CH.dbd.CH--, --N.dbd.CH--, --N.dbd.N--, --S--, --O-- or ##STR2## wherein R.sup.3 is hydrogen or C.sub.1 -C.sub.3 alkyl, Y is a halogen atom, a straight or branched C.sub.1 -C.sub.6 alkyl, a C.sub.3 -C.sub.6 cycloalkyl or cycloalkoxy, and other substituents, n is 0 or an integer of 1 to 3, and when n is 2 or 3, Y may be same or different, with the proviso that when B is --CH.dbd.CH--, n is an integer of 1 to 3 and at least one of Y is --O--W, as this term is defined in the specification. A process for the preparation of said derivatives is also provided. These derivatives are useful as an active ingredient of insecticidal, acaricidal, nematicidal and/or fungicidal compositions for agricultural and horticultural uses as well as of expellent compositions for ticks parasitic on animals.
一种通式为(I)的3(2H)-吡啶酮衍生物:##STR1##
其中,R是直链或支链C.sub.2-C.sub.6烷基,A是直链或支链C.sub.1-C.sub.6烷基或卤素原子,X是--O--或--S--,R.sup.1和R.sup.2各自独立地是氢原子或C.sub.1-C.sub.3烷基,B是--CH.dbd.CH--,--N.dbd.CH--,--N.dbd.N--,--S--,--O--或##STR2##
其中,R.sup.3是氢或C.sub.1-C.sub.3烷基,Y是卤素原子,直链或支链C.sub.1-C.sub.6烷基,C.sub.3-C.sub.6环烷基或环烷氧基,以及其他取代基,n为0或1至3的整数,当n为2或3时,Y可以相同或不同,但当B为--CH.dbd.CH--时,n为1至3的整数,并且至少一个Y为--O--W,如在说明书中定义的那样。还提供了制备该衍生物的方法。这些衍生物可用作农业和园艺用杀虫剂、杀螨剂、杀线虫剂和/或杀真菌剂组合物的活性成分,以及用于驱除寄生在动物身上的蜱的驱虫剂组合物。
