Trifluoromethoxy-phenyl substituted tetramic acid-derivatives (I), are new. Trifluoromethoxy-phenyl substituted tetramic acid-derivatives of formula (I), are new. J1a : trifluoromethoxy; X : H, alkyl, halo, haloalkyl, alkoxy or haloalkoxy; Y1a : H, alkyl or halo, where at least one of J1a, X or Y1a is present at position-2 of the phenyl residue and is at the same time unequally hydrogen; either A : alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl, optionally saturated cycloalkyl (all optionally substituted by halo and at least a ring atom is optionally substituted by a heteroatom), aryl, arylalkyl, hetaryl (all optionally substituted by halo, (halo)alkyl, (halo)alkoxy, cyano or nitro) or H; and B1a : H or alkoxyalkyl; and D : H or a residue optionally substituted by alkyl, alkenyl, alkynyl, alkoxyalkyl, optionally saturated cycloalkyl, in which optionally one or more ring members are substituted by heteroatom, arylalkyl, aryl, hetarylalkyl or hetaryl; or C+A+B1a : optionally saturated, substituted and heteroatom containing cyclic group; or A+D : optionally saturated and at least a heteroatom containing, in A, D-parts optionally substituted cyclic group; G : H, carboxy group of formula (-CO-R 1>) or (-C(=L)-M-R 2>), sulfur dioxide group of formula (-SO 2-R 3>), phosphorus group of formula (-P(R 4>)(R 5>)(=L)), E or (-C(=L)-N(R 6>)(R 7>)); E : an equivalent metal ion or an ammonium ion; L, M : O or S; R 1>optionally halo substituted alkyl, alkenyl, alkoxyalkyl, alkylthioalkyl or polyalkoxyalkyl, optionally halo-, alkyl- or alkoxy substituted cycloalkyl, which is interrupted by at least a heteroatom, optionally substituted phenyl, phenylalkyl, hetaryl, phenoxyalkyl or hetaryloxyalkyl; R 2>optionally halo substituted alkyl, alkenyl, alkoxyalkyl or polyalkoxyalkyl, optionally substituted cycloalkyl, phenyl or benzyl; R 3>-R 5>optionally halo substituted alkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkenylthio or cycloalkylthio, or optionally substituted phenyl, benzyl, phenoxy or phenylthio; and either R 6>, R 7>optionally halo substituted alkyl, cycloalkyl, alkenyl, alkoxy or alkoxyalkyl, optionally substituted phenyl or benzyl, or H; or NR 6>R 7>cyclic group interrupted optionally by O or S. Independent claims are included for: (1) the preparation of (I); (2) the preparation of an agent to combat parasite and/or undesirable plant growth comprising mixing (I) with a diluent and/or a surface active material; (3) an agent comprising an active agent combination
