Embodiment A

[0131] Horseradish ape leaf beetle (Phaedoncochleariae) – spray test

[0132] Solvent: 78.0 parts by weight of acetone

[0133] 1.5 parts by weight of dimethylformamide

[0134] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0135] To prepare a suitable preparation of the active compound, 1 part by weight of the 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. To prepare a suitable spore suspension, the spores are diluted to the desired concentration with water containing an emulsifying agent.

[0136] Chinese cabbage ( Brassica pekinensis ) leaves are sprayed with the preparation of active ingredient of the desired concentration. Once dry, the leaves are infested with larvae of the mustard beetle (horseradish beetle).

[0137] After a specified period of time, the mortality in % is determined. 100% means that all beetle ...

[0145] 1.5 parts by weight of dimethylformamide

[0146] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0147] To prepare a suitable preparation of the active compound, 1 part by weight of the 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. To prepare a suitable spore suspension formulation, the spores are diluted to the desired concentration with water containing an emulsifying agent.

[0148] Maize (Zeamais) leaf parts are sprayed with the preparation of active ingredient of the desired concentration. Once dry, the leaf sections are infested with Spodoptera frugiperda larvae.

[0149] After a specified period of time, the mortality in % is determined. 100% means that all caterpillars have been killed and 0% mea...

Embodiment C

[0155] Green peach aphid (Myzuspersicae) – spray test

[0156] Solvent: dimethylformamide of 7 parts by weight

[0157] Emulsifier: Alkyl aryl polyglycol ether

[0158] To prepare a suitable active compound formulation, 1 part by weight of active compound is mixed with the abovementioned amount of solvent and diluted to the desired concentration with water containing emulsifier at a concentration of 1000 ppm. Other test concentrations were prepared by dilution with water containing emulsifier. If necessary, ammonium salts and / or penetration enhancers are added at a dose of 1000 ppm to the desired concentration.

[0159] Cabbage ( Brassica oleracea ) which is heavily infested by the green peach aphid ( Myzus persicae ) is treated by spraying with a preparation of active compound of the desired concentration.

[0160] After a specified period of time, the mortality in % is determined. 100% means that all aphids have been killed; 0% means that none of the aphids have been k...

Abstract

The present invention relates to novel active compound combinations comprising at least one known compound of the formula (I) (I) in which X, R1 to R4, A, n, Y, and m are as defined in the description, and at least one further known active compound from the class of avermectins / milbemycins, which combinations are highly suitable for controlling animal pests such as insects and unwanted acarids.

Description

[0001] The present invention relates to novel active compound combinations, which firstly comprise at least one known compound of formula (I) and secondly comprise at least one active compound selected from the group consisting of avermectin / milbemycin Compounds, said combinations are extremely suitable for controlling animal pests, such as insects and unwanted mites. Background technique [0002] Phthalic acid amides (Ryanodine receptor inhibitors) are known to have insecticidal activity (see eg EP0919542, WO2004 / 018410 or WO2010 / 012442). Phthalic acid amides containing cyano groups and their preparation are also disclosed in WO2012 / 034472. [0003] In addition, many heterocyclic compounds, organotin compounds, benzoylureas and pyrethroids are known to have insecticidal and acaricidal properties. However, the activity of these compounds is not always satisfactory. Contents of the invention [0004] The first aspect relates to an active compound combination comprising at l...
