Insecticide compositions of 2-cyanobenzolsulfonamides and their isomeric forms with improved properties

Composition (A) comprises at least an insecticidal and/or acaricidal active agent of the class of 2-cyanobenzolsulfonamide (I) and its isomeric form; and at least one ammonium- or phosphonium-salt (II). Composition (A) comprises at least an insecticidal and/or acaricidal active agent of the class of 2-cyanobenzolsulfonamide (I) and its isomeric form; and at least one ammonium- or phosphonium-salt of formula ((D +>(R 6>)(R 7>)(R 8>)(R 9>)) n(R 10>)(n ->)) (II). D : N or P; R 6>-R 9>1-8C-alkyl or unsaturated 1-8C-alkyl (both optionally substituted by halo, nitro or CN), or H; n : 1-4; and R 10>organic or inorganic anion. An independent claim is included for a method of increasing the effect of plant protective agent containing the active agent of class of 2-cyanobenzolsulfonamide of formula (I) and or its isomeric forms of formula (I-A) or (I-B), using ready-to-use agent (syringe broth), which is prepared using (II). A : H, 1-6C alkyl or 2-6C alkenyl; R 1>H, halo, 1-4C (halo)alkyl or 1-4C (halo)alkoxy; R 2>T or H; T : 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl, 3-8C cycloalkyl or 1-4C alkoxy (all partially or completely halogenated and optionally substituted by 1-3 groups of 1-4C alkylsulfinyl, 1-4C alkylsulfonyl, 1-4C (halo)alkoxy, 1-4C (halo)alkylthio, 1-4C alkoxycarbonyl, CN, amino, (1-4C alkyl)amino, di-(1-4C alkyl)amino, 3-8C cycloalkyl or phenyl (partially or completely halogenated and optionally substituted by 1-3 groups of 1-4C (halo)alkyl or 1-4C (halo)alkoxy)); and R 3>-R 5>H, halo, CN, nitro, 1-6C alkyl, 3-8C cycloalkyl, 1-4C haloalkyl, 1-4C (halo)alkoxy, 1-4C (halo)alkylthio, 1-4C alkylsulfinyl, 1-4C alkylsulfonyl, 2-6C alkenyl, 2-6C alkynyl, 1-4C alkoxycarbonyl, amino, (1-4C alkyl)amino, di-(1-4C alkyl)amino, aminocarbonyl, (1-4C alkyl)aminocarbonyl or di-(1-4C alkyl)aminocarbonyl. In formula (I-A), R 2>T. [Image] ACTIVITY : Insecticide; Acaricide. MECHANISM OF ACTION : None given. Die vorliegende Erfindung beinhaltet 2-Cyanobenzolsulfonsäureamide der Formel (I) und deren isomere Formen (I-A) und (I-B) wobei R 1 , R 2 , R 3 , R 4 , R 5 und A die oben angegebene Bedeutung haben- zur Bekämpfung von tierischen Schädlingen unter Verwendung von Penetrationsförderem und/oder Ammonium- oder Phosphoniumsalzen.
