ABSTRACT Novel 3(2H)-pyridazinone derivatives having the general formula (I): 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: Image when A is a straight or branched C1 to C6 alkyl, and Q denotes a group: Image 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-, -CR6R7O- or Image (wherein, R6 and R7 denote each independently hydrogen or a C1 to C3 alkyl); m is 0 or 1; Y denotes hydrogen, a halogen, a C1 to C6 alkyl, a cycloalkyl, a cycloalkyloxy, a C1 to C6 alkyloxy, a C1 to C6 alkylthio, a C1 to C6 alkylsulfinyl, a C1 to C6 alkylsulfonyl, a lower haloalkyl, a lower haloalkyloxy, a lower haloalkylthio, a lower alkenyloxy, trimethylsilyl, a lower alkoxycarbonyl, dimethylamino, nitro, cyano, SCN, Image wherein, Z denotes a halogen, a lower alkyl, a lower alkoxy, a cycloalkyl, a lower haloalkyl, a lower alkoxycarbonyl or nitro and ? is 0 or an integer of from 1 to 5, said Z being the same or different when / is an integer of 2 to 5); n is an integer of from 1 to 5, said Y being the same or different when n is an integer of 2 to 5; R 3 and R4 denote each independently hydrogen, a halogen, a lower alkyl or 4-methoxyphenyl, or R3 and R4 together form a direct bond so as to form a triple bond between the carbon atoms to which they are linking; and R5 denotes a C1 to C6 alkyl, a C2 to C6 alkenyl, Image , or a halogen (wherein, Y and n are as defined in the above). 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.
