## Abstract

The invention relates to insecticidal compositions which comprise A) inorganic or organic ammonium salts of the formula I ##STR1## in combination with at least one compound from the group consisting of the compounds silafluofen (4-ethoxyphenyl-›3-(4-fluoro-3-phenoxyphenyl)propyl!dimethylsilane), MTI-732, imidacloprid, ethofenprox (Trebon, MTI-500, (2-(4-ethoxyphenyl)-2-methylpropyl-3-phenoxybenzyl ether), PP 682 (ICI-A5682), TI304, natural or synthetic pyrethroids and phosphorothioates.

## Claims

### Claim 1

An insecticidal composition comprising synergistic insecticidally effective amounts of C.sub.10 -C.sub.18 alkyl benzyl dimethyl ammonium chloride, in combination with at least one compound selected from the group consisting of
C) MTI-732 (formula III), ##STR10## E) ethofenprox (Trebon, MTI-500, (2-(4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether, formula V), ##STR11## F) PP 682 (ICI-A5682, formula VI), ##STR12## wherein the compounds C), E) and F) and the ammonium salt are present in a ratio by weight of 20:1 to 1:10,000.

### Claim 2 (depends on 1)

The insecticidal composition of claim 1, wherein the ratio by weight is 20:1 to 1:5000.

### Claim 3 (depends on 3)

The insecticidal composition of claim 3, which comprises 0.1 to 50% by weight of the active insecticidal mixture and 99.5-50% by weight of customary formulation auxiliaries for preparations in the form of sprayable solutions.

### Claim 4 (depends on 1)

A method of controlling insects, which comprises applying a synergistic insecticidally effective amount of the composition of claim 1 to the insects or their wood, soil or plant habitats.

### Claim 5 (depends on 4)

The method of claim 4, wherein an application rate of 15 to 600 l of the synergistic mixtures is applied per m.sup.3 of wood.

### Claim 6 (depends on 4)

The method of claim 4, wherein spray mixtures are applied which contain 0.001 to 1000 g/l of the active insecticidal combination.

### Claim 7 (depends on 4)

The method of claim 4, wherein the active insecticidal ingredients are applied together or one shortly after the other.

### Claim 8

An insecticidal composition comprising synergistic insecticidally effective amounts of C.sub.10 -C.sub.18 alkyl benzyl dimethyl ammonium chloride, in combination with
E) ethofenprox (Trebon, MTI-500, (2-(4-ethyoxyphenyl)-2-methylpropyl 3-phenoxybenzyl ether, formula V), ##STR13## wherein the compound E and the ammonium salt are present in a ratio by weight of 20:1 to 1:10,000.
