Solid formulation of insecticidal mixtures having particularly good dispersion properties

A solid-state composition of water-dispersible granules comprising:

• a. tetramic acid derivatives of formula (I)
• in which
• W and Y are independently hydrogen, C1-C4-alkyl, chlorine, bromine, iodine or fluorine, X is C1-C4-alkyl, C1-C4-alkoxy, chlorine, bromine or iodine,
• A, B and the carbon atom to which they are bonded are C3-C6-cycloalkyl substituted by an C1-C4-alkyl- or C1-C4-alkoxy-C1-C2-alkyl-substituted alkylenedioxyl group that forms a 5-membered or 6-membered ketal together with the carbon atom to which it is bonded,
• G is hydrogen (a) or one of (b), (c), or (d) below:
• in which
• E is a metal ion or an ammonium ion,
• M is oxygen or sulfur,
• R1 is straight-chain or branched C1-C6-alkyl,
• R2 is straight-chain or branched C1-C6-alkyl;
• b. at least one basic salt;
• c. at least one further inorganic salt from the group of the carbonates and hydrogencarbonates;
• d. at least one dispersant;
• e. at least one wetting agent;
• f. at least one filler;
• and
• g. at least one structure former.
