There are disclosed novel substituted 2-phenoxyphenoxyethylcarbamic acid esters of the formula I <IMAGE> in which R1 represents C1-C4-alkyl or C3-C4-alkenyl, R2 represents C1-C4-alkyl or a radical of the formula <IMAGE> -C(CH3)2-CN or -N(R9)-COO-C1-C4-alkyl, R3 and R4 independently of each other represent hydrogen or methyl, R5 represents fluorine or chlorine, R6 represents either the same substituents as R5 or hydrogen, R7 and R8 independently of each other represent hydrogen, halogen, C1-C4-alkyl, C1-C4-alkoxy or nitro, R9 represents C1-C4-alkyl and n represents zero, one or two, their preparation, their use in pest control, and pesticides which contain these carbamic acid esters as active substance. The preferred field of application is the control of pests on animals and plants, in particular eggs and larvae of phytophagous harmful insects and phytophagous harmful mites. |
