Abstract

The invention relates to novel compounds of the formula (I)in whichW, X, Y, Z, A, B, D, Q1, Q2 and G are as defined above, to a plurality of processes for their preparation and to their use as pesticides and/or herbicides and/or fungicides and also to selective herbicidal compositions comprising, firstly, the 3′-alkoxyspirocyclopentyl-substituted tetramic and tetronic acids of the formula (I) and, secondly, at least one crop plant compatibility-improving compound, and also to boosting the activity of crop protection compositions comprising active compounds from the class of the 3′-alkoxyspirocyclopentyl-substituted tetramic and tetronic acids of the formula (I) by adding ammonium salts and/or phosphonium salts or by adding ammonium salts and/or phosphonium salts and penetrants, to the corresponding compositions, to processes for their preparation and to their use in crop protection.
