Embodiment A

[0200] Green peach aphid (Myzus persicae) test

[0201] Solvent: acetone of 78 parts by weight

[0202] 1.5 parts by weight of dimethylformamide

[0203] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0204] To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and diluted to the desired concentration with water containing emulsifier.

[0205] Cabbage leaves (Brassica oleracea) which are heavily infested by the peach aphid (Myzus persicae) are treated by spraying with an active compound preparation of the desired concentration.

[0206] After the expected time, the killing effect in % is determined. 100% means that all green peach aphids have been killed; 0% means that none of the green peach aphids have been killed. The data were entered into the Colby formula to determine the kill rate.

[0207] In this test, for example, the following active compound complexes ...

Embodiment B

[0213] Mustard leaf beetle (Phaedon cochleariae) larval test

[0214] Solvent: acetone of 78 parts by weight

[0215] 1.5 parts by weight of dimethylformamide

[0216] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0217] To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and diluted to the desired concentration with water containing emulsifier. Cabbage leaves (Brassica oleracea) which are still moist and are colonized with larvae of the mustard leaf beetle (Phaedon cochleariae) are treated by spraying with the preparation of active compound of the desired concentration.

[0218] After the expected time, the killing effect in % is determined. 100% means that all beetle larvae have been killed; 0% means that none of the beetle larvae have been killed. The data were entered into the Colby formula to determine the kill rate.

[0219] In this test, the following ac...

Embodiment C

[0225] Fall armyworm (Spodoptera frugiperda) larva test

[0226] Solvent: acetone of 78 parts by weight

[0227] 1.5 parts by weight of dimethylformamide

[0228] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0229] To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and diluted to the desired concentration with water containing emulsifier.

[0230] Cabbage leaf leaves (Brassica oleracea), which are still moist and are colonized with larvae of the fall armyworm (Spodoptera frugiperda), are treated by spraying with the preparation of active compound of the desired concentration.

[0231] After the expected time, the killing effect in % is determined. 100% means that all caterpillars have been killed; 0% means that none of the caterpillars have been killed. The data were entered into the Colby formula to determine the kill rate.

Abstract

The invention relates to new compounds of the formula (I) comprising active substance combinations and to spinetoram having very good insecticidal and/or acaricidal properties.

Description

technical field [0001] The present invention relates to novel active compound complexes comprising: firstly, the known cyclic ketoenols and, secondly, other known insecticidally active compounds, said complexes being particularly suitable for controlling animal pests such as insects and / or or harmful mites. Background technique [0002] Certain ketoenols are known to have herbicidal and / or insecticidal and / or acaricidal properties. Although the activity of these compounds is good at low application rates, in some cases they are less effective. [0003] Compounds known to have herbicidal and / or insecticidal and / or acaricidal properties are 1H-3-arylpyrrolidine-2,4-dione derivatives (EP-A-456 063, EP-A-521 334, EP-A-596 298, EP-A-613 884, EP-A-613 885, WO 95 / 01 971, WO 95 / 26954, WO 95 / 20572, EP-A-0 668 267, WO 96 / 25395, WO 96 / 35664, WO 97 / 01 535, WO 97 / 02 243, WO 97 / 36 868, WO 97 / 43275, WO 98 / 05638, WO 98 / 06721, WO 98 / 25928, WO 99 / 24437, WO 99 / 43649 , WO 99 / 48869 and WO 99...
