Compounds of the general formula I <IMAGE> (I) in which A denotes a radical of the formula A1, A2 or A3 <IMAGE> (A1) <IMAGE> (A2) <IMAGE> (A3) R1 to R3 in each case independently of one another denote hydrogen or halogen, the radicals R4 in each case independently of one another denote halogen, (C1-C3)halogenoalkyl or nitro, R5 denotes (C1-C5)alkyl, which can be halogenated, X denotes oxygen or sulfur, n denotes a number from 0 to 2 and m denotes a number from 1 to 4 with the proviso that (R4)m does not by itself denote halogen or by itself denote nitro, and where A=A1, salts thereof which can be used in agriculture, have advantageous acaricidal and insecticidal properties. Processes for the preparation of the compounds of the formula I are furthermore described. |
