1. Agents for combating pests, characterised in that they contain substituted malonic acid derivatives of the general formula I see diagramm : EP0108351,P24,F3 wherein R**1 = phenyl which is mono- to trisubstituted in the 3,4,5-position by identical or different halogen substituents, R**2 = hydrogen, C1-4 -alkyl, optionally halogen-substituted C1-4 -alkyl, aminosulphonyl, C1-4 -alkylcarbonyl, optionally halogen-substituted phenylcarbonyl, phenylsulphenyl, optionally halogen-substituted C1-4 -alkylsulphenyl, trialkylsilyl or a radical of the formula see diagramm : EP0108351,P24,F4 wherein R**5 represents hydrogen and R**6 represents optionally halogen-substituted phenyl or phenylcarbonyl or C1-4 -alkyl or C1-4 -alkylcarbonyl, R**3 and R**4 are identical or different and represent amino, trimethylsilylamino, formylamino, C1 -C4 -alkylcarbonylamino, alkylamino, or trialkylsilyl-alkylamino, and, if R**2 represents hydrogen, R**3 and R**4 may not simultaneously represent amino. |
