Embodiment A

[0290] Cotton bollworm (Heliothis armigera) test

[0291] Solvent: 7 parts by weight dimethylformamide

[0292] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0293] To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the abovementioned amounts of solvent and emulsifier, and the concentrate is diluted to the desired concentration with water containing the emulsifier.

[0294] Soybean shoots (Glycine max) are treated by being dipped into the preparation of active compound of the desired concentration and populated with caterpillars of the cotton bollworm (Heliothis armigera) while the soya leaf is still moist.

[0295] The kill in % is determined after the desired time. Where 100% means that all caterpillars have been killed; 0% means that no caterpillars have been killed. The measured kill rate was used for calculation in the Carpenter formula (see previous page).

[0296] In this test, the following combinat...

Embodiment B

[0310] Myzus test

[0311] Solvent: 7 parts by weight dimethylformamide

[0312] Emulsifier: 2 parts by weight alkyl aryl polyglycol ether

[0313]To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the abovementioned amounts of solvent and emulsifier, and the concentrate is diluted to the desired concentration with water containing the emulsifier.

[0314] Cabbage leaves ( Brassica oleracea ) heavily infested with green peach aphid ( Myzus persicae ) are treated by being dipped into the preparation of active compound of the desired concentration.

[0315] The kill in % is determined after the desired time. 100% of these indicated that all aphids were killed. The measured kill rate was used for calculation in the Carpenter formula.

[0316] In this test, the following combinations of active compounds according to the invention exhibit enhanced synergistic activity compared to the active compounds administered alone.

Embodiment C

[0330] Plutella test, susceptible species

[0331] Solvent: 7 parts by weight dimethylformamide

[0332] Emulsifier: 2 parts by weight alkyl aryl polyglycol ether

[0333] To prepare a suitable active compound preparation, 1 part by weight of active compound is mixed with the abovementioned amounts of solvent and emulsifier, and the concentrate is diluted to the desired concentration with water containing the emulsifier.

[0334] Cabbage leaves (Brassica oleracea) are treated by being dipped into the preparation of active compound of the desired concentration and populated with caterpillars of the diamondback moth (Plutellaxylostella, a sensitive species) while the leaves are still moist.

[0335] The kill in % is determined after the desired time. Where 100% means that all caterpillars have been killed; 0% means that no caterpillars have been killed. The measured kill rate was used for calculation in the Carpenter formula.

[0336] In this test, the following combinations...

Abstract

The invention relates to insecticidal mixtures containing a compound of formula (I) and at least one other known agent from the series abamectin, emamectin or emamectin benzoate, methiocarb, ss-cyfluthrin, and lambda-cyhalothrin. Also disclosed is the use of said mixtures for protecting plants from infestations by parasites.

Description

technical field [0001] The present invention relates to novel active compound combinations comprising firstly the known active compound Clothianidin and secondly at least one further known insecticidally active compound, said combinations having very good insecticidal and acaricidal properties. Background technique [0002] Known Clothianidin shown in the following formula [0003] [0004] Useful for controlling animal pests, especially insects (see EP-A-376279 and EP 375907). This compound has good activity; however, it is sometimes unsatisfactory at low application rates or against individual pests. [0005] Also known compounds are abamectin (II) (DE 2717040), Emamectin (III) or Emamectin benzoate (IIIa) (EP 089202), methiocarb (IV) (US3,313,684), β-cyfluthrin (V) (EP 206149) and lambda-cyhalothrin (VI) (EP106469) are useful for controlling insects and / or mites. Contents of the invention [0006] It has been found now that Clothianidin shown in the formula (I) is...
