| abstract |
The present invention relates to novel tetramic acid and tetronic acid derivatives substituted with spiro-phenoxyrocyl cyclic of formula (I), wherein A and B and the carbon atom to which they are attached represent a tetrahydrofuran ring or a ring of tetrahydropyran respectively substituted, where appropriate, with alkyl, halogenoalkyl, alkoxy, alkoxyalkyl or phenyl, if the case substituted, and W, X, Y, Z, D, Q1, Q2 and G have the meanings given above, to various processes for their preparation and its use as pesticides and / or herbicides. The subject of the invention are also selective herbicidal agents that contain, on the one hand, derivatives of tetramic acid and tetronic acid substituted with spiro-phenoxy oxoespirocyclics and, on the other hand, a compound for improving tolerance in crop plants. The invention further relates to the increase in the effect of phytosanitary agents containing compounds of formula (I) by the addition of ammonium or phosphonium salts and, if necessary, penetration enhancers. |
