发明名称 PYRIDAZINONE DERIVATIVES, PREPARATION THEREOF AND INSECTICIDAL, ACARICIDAL, FUNGICIDAL COMPOSITIONS
摘要 <p>Novel 3(2H)-pyridazinone derivatives having the formula I: (I) wherein, R is a straight or branched C2 to C6 alkyl, R1 and R2 are each independently hydrogen or a lower alkyl, R4 is a halogen, R3 is a halogen, an alkyl, a cycloalkyl, an alkoxy, a haloalkyl, a haloalkoxy, -CN, -NO2, a phenyl, a benzyloxyy, a benzyl, a phenoxy, a phenylthio, a pyridyloxy, a quinoxalyloxy, a lower alkenyloxy, a lower alkylthio, a lower haloalkylthio, Si(CH3)3, -OH, -N(CH3)2, -SCN, -COOCH3 or -OCH(CH3)COOC2H5, and n is an integer of 1 to 5, said R3 being the same or different when n is an integer of 2 to 5. 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.</p>
