OXASPIROCYCLIC SPIRO-SUBSTITUTED TETRAMIC ACID AND TETRONIC ACID DERIVATIVES

摘要

The present invention relates to novel oxaspirocyclic spiro-phenyl-substituted tetramic acid and tetronic acid derivatives of the formula (I), in which W, X, Y, Z, A, B, D, Q1, Q2, and G have the meanings given above, to several processes for their preparation and to their use as pesticides and/or herbicides. The invention also relates to selectively herbicidal compositions which comprise oxaspirocyclic spiro-phenyl-substituted tetramic acid and tetronic acid derivatives on the one hand and a compound that improves cultivated plant compatibility on the other hand. The invention further relates to the increase in the effect of crop protection compositions comprising compounds of the formula (I) through the additions of ammonium or phosphonium salts and optionally penetration promoters.
