Claims8
A method for the control of insect or acarid pests which comprises contacting said pests or their food supply, habitat or breeding grounds with a pesticidally effective amount of a compound having the structural formula I
- wherein
- A and B each independently represent an optionally substituted aryl group, with a proviso that A is not 4-nitrophenyl;
- R1 represents a hydrogen or halogen atom or an optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkoxyalkyl, alkoxyalkoxy group;
- or an alkylthio group, alkylsulphinyl or alkylsulphonyl group, an amino, alkylamino or dialkylamino group or a cyano, nitro, haloalkyl, haloalkoxy, haloalkylthio or SF5 group, one of Y and Z represents N and the other represents CR2, in which R2 has the meaning given for R1;
- X represents O or NR, in which R represents a hydrogen atom or an alkyl group.
A method for the control of insect or acarid pests which comprises contacting said pests or their food supply, habitat or breeding grounds with a pesticidally effective amount of a compound having structural formula I
- wherein A represents an optionally substituted aryl group and B represents a phenyl group being substituted by one or more of the same or different substituents selected from halogen atoms, alkyl, alkoxy, cyano, nitro, haloalkyl, haloalkoxy, alkylthio, haloalkylthio, alkylsulphinyl, alkylsulphonyl and SF5 groups;
- R1 represents a hydrogen or halogen atom or an optionally substituted alkyl, alkenyl, alkinyl, alkoxy, alkoxyalkyl, alkoxyalkoxy group;
- or an alkylthio group, alkylsulphinyl or alkylsulphonyl group, an amino, alkylamino or dialkylamino group or a cyano, nitro, haloalkyl haloalkoxy, haloalkylthio or SF5 group, one of Y and Z represents N and the other represents CR2, in which R2 has the meaning given for R1;
- X represents O or NR, in which R represents a hydrogen atom or an alkyl group.
