Embodiment A1

[0176] Horseradish ape leaf beetle (Phaedoncochleariae) – spray test

[0177] Solvent: 78.0 parts by weight of acetone

[0178] 1.5 parts by weight of dimethylformamide

[0179] Emulsifier: 0.5 parts by weight of alkyl aryl polyglycol ether

[0180] To prepare a suitable active compound preparation, 1 part by weight of active compound is admixed with the abovementioned amounts of solvent and emulsifier, and the concentrate is diluted with water containing the emulsifier to the desired concentration. To prepare a suitable spore suspension, the spores are diluted to the desired concentration with water containing an emulsifier.

[0181] Disc leaves of Chinese cabbage ( Brassicapekinensi ) are sprayed with the preparation of active ingredient of the desired concentration. Once dry, the discs are infested with larvae of the mustard beetle (horseradish beetle).

Abstract

The present invention relates to novel active compound combinations comprising at least one known compound of the formula (I) in which X, R1 to R4, A, n, Y, and m areas defined in the description,and at least one further known active compound from the class of the of tetronic and tetramic acid derivatives, diacylhydrazines, benzoylureas and further classes, 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 comprising: firstly, at least one known compound of formula (I) and, secondly, at least one active compound from tetronic acid and tetramic acid (tetramicacid) derivatives, dihydrazides, benzoylureas or other active compounds, the combination is very suitable for controlling animal pests, such as insects and unwanted mites. Background technique [0002] Phthalamides (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, a number of heterocyclic compounds, organotin compounds, benzoylureas, pyrethroids and others 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...
