Abstract
Novel 3(2H)-pyridazinone derivatives of the formula (I): ##STR1## wherein, X represents a halogen, an alkyl, a haloalkyl, a haloalkoxy atoms, NO.sub.2, an alkoxy or ##STR2## (wherein, R represents an alkyl); n is 1 to 4; PA0 A represents hydrogen, a halogen, an alkyl or an alkoxy; PA0 B represents CX.sub.1 (wherein, X.sub.1 represents H or a halogen) or N; PA0 R.sup.1 and R.sup.2 represent each independently H or an alkyl; PA0 E represents H, a halogen, an alkoxy or --OH; and PA0 Q represents: ##STR3## (wherein, Y represents a halogen, an alkyl, an alkoxy, a haloalkyl, a haloalkoxy, CN, ##STR4## (wherein, Z represents a halogen, an alkyl, an alkoxy or a haloalkyl atoms, and l is 0, 1 to 5, said Z being the same or different when l is 2 to 5); and m is 1 to 5, said Y being the same or different when n is 2 to 4. A process for preparation of said derivatives is also provided. These derivatives are useful as an active ingredient of insecticidal composition.
