The present invention relates to novel 4′4′-dioxaspiro-spirocyclically substituted tetramates of the formula (I) in which A, B, G, m, n, W, X, Y and Z to a plurality of processes for their preparation and to their use as pesticides and/or herbicides. The invention also provides selectively herbicidal compositions comprising firstly the 4′4′-dioxaspiro-spirocyclically substituted tetramates and secondly a crop plant compatibility-improving compound. The present invention also relates to novel water-soluble concentrates of 4′4′-dioxaspiro-spirocyclically substituted tetramates and their enols, to processes for preparing these formulations and to their use as pesticides and/or herbicides. The present invention furthermore relates to increasing the activity of crop protection compositions comprising in particular 4′4′-dioxaspiro-spirocyclically substituted tetramates by adding ammonium salts or phosphonium salts and, if appropriate, penetrants, to the corresponding compositions, to processes for their preparation and to their use in crop protection as insecticides and/or acaricides and/or for preventing unwanted plant growth.
