Compounds of the general formula I wherein A is a radical of the formulas A¹, A² or A³ R¹ to R³ each independently of one another are hydrogen or halogen, R⁴ each independently of one another halogen, (C₁-C₃) haloalkyl, or nitro, R⁵ (C₁-C₅) alkyl, which can be halogenated, X oxygen or sulfur, n is a number from 0 to 2 and m is a number from 1 to 4 mean, with the proviso that (R⁴) m is not halogen by itself, or nitro by itself, and in the case A = A¹ their agricultural salts have advantageous acaricidal and insecticidal properties.n n n Processes for the preparation of the compounds of the formula I are also described. |
