Novel 3(2H)-pyridazinone derivatives having the general formula (I): STR1 wherein, R denotes a straight or branched C1 to C6 alkyl; A denotes a straight or branched C1 to C6 alkyl or a halogen; X denotes oxygen or sulfur atom; Q denotes a group; STR2 when A is a straight or branched C1 to C6 alkyl, and Q denotes a group: STR3 when A is a halogen atom; R1 and R2 denote each independently hydrogen, a lower alkyl, a lower haloalkyl, or 4-tert-butylphenyl; B denotes --CR6 =CR7 --, --CR6 R7 O--, or STR4 (wherein, R6 and R7 denote various specific organic radicals. A process for 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.
