Pyridylphosphates, a process for their preparation, agents containing them, and their use as pesticides compounds of the formula I <IMAGE> (I) where A is N or N->O, R1, R2 independently of one another are halogen, X=O or S, R3 and R4 independently of one another are H, halogen, phenyl, phenylthio, phenoxy, phenylsulfenyl, phenylsulfinyl, phenylsulfonyl, phenylsulfonylamino, phenylamino, phenylcarbonylamino, all of which can be substituted in the phenyl moiety by halogen, alkyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, haloalkoxy, haloalkyl, nitro, dialkylamino, alkylthio, cyano or carboxyl, or are alkyl, alkoxy, alkylthio, alkylcarbonyl, alkoxycarbonyl, haloalkoxy, haloalkyl, alkylsulfenyl, alkylsulfinyl, alkylsulfonyl, cyano, nitro, carboxyl, sulfo, heteroaryl, heteroaryloxy, alkenyl, alkinyl, both of which can optionally be mono- substituted or polysubstituted by halogen, or are amino, monoalkylamino, dialkylamino, it being possible for the two alkyl groups, together with the N atom, to form a 5- to 7-membered ring, or are alkylsulfonylamino, thiocyanato or cyanato and R5 and R6 independently of one another are alkyl, alkoxy, monoalkylamino, dialkylamino, it being possible for the two alkyl groups together with the N atom to form a 5- to 7-membered ring, or are phenyl, phenoxy, phenylthio, all of which can be substituted by halogen, alkyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, haloalkoxy, haloalkyl, nitro, dialkylamino, alkylthio, cyano or carboxyl, or denote alkylthio, have advantageous insecticidal, acaricidal or nematocidal properties.
