Embodiment A

[0159] Test on Apple Panonychus ulmi

[0160] Solvent: dimethylformamide of 7 parts by weight

[0161] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0162] To prepare a suitable active ingredient formulation, 1 part by weight of active ingredient is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

[0163]Plum tree branches (Prunus domestica) infested with mixed populations of the fruit mite (Panonychus apple) are sprayed with the preparation of active ingredient at the desired concentration.

[0164] After the desired time elapses, the % kill rate is determined. 100% means that all spider mites have been killed; 0% means that none of the spider mites have been killed.

[0165] In this test, the following combinations of active ingredients according to the application showed a synergistic activity relative to the active ingredients applied individually:

Embodiment B

[0173] Two-spotted spider mite (Tetranychus urticae) test (OP resistance)

[0174] Solvent: dimethylformamide of 7 parts by weight

[0175] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0176] To prepare a suitable active ingredient formulation, 1 part by weight of active ingredient is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

[0177] Cucumis sativus plants which are heavily infested by the common spider mite (Tetranychus urticae) are sprayed with the preparation of active ingredient at the desired concentration.

[0178] After the desired time elapses, the % kill rate is determined. 100% means that all spider mites have been killed; 0% means that none of the spider mites have been killed.

Embodiment C

[0187] Test on Citrus Panonychus citri

[0188] Solvent: dimethylformamide of 7 parts by weight

[0189] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0190] To prepare a suitable active ingredient formulation, 1 part by weight of active ingredient is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

[0191] Citrus plants (citrus limon) infested by mixed populations of the citrus mite Panonychus citri are sprayed with a preparation of active ingredient of the desired concentration.

[0192] After the desired time elapses, the % kill rate is determined. 100% means that all spider mites have been killed; 0% means that none of the spider mites have been killed.

[0193] In this test, the following combinations of active ingredients according to the application exhibited a synergistic activity relative to the active ingredients applied individually:

[0194] Form C

Abstract

The invention relates to the use of active substance combinations that consist of a known dihydrofuranone derivative and other known pesticidal active substances for controlling animal pests, especially from the subclass Acari.

Description

technical field [0001] The present invention relates to the use of an active ingredient combination for controlling animal pests, in particular of the order Acari (der Ordnung der Milben), said active ingredient combination consisting of dihydrofuranone derivatives known on the one hand and on the other hand other known insecticidally active ingredients. Background technique [0002] It is known that the dihydrofuranone derivatives of formula (I) [0003] [0004] Useful for controlling animal pests such as insects and undesirable mites (see EP-A-0528156). The activity of this substance is very good, but sometimes still insufficient at low application rates. [0005] Furthermore, mixtures of (I) and other insecticides and / or acaricides are also known: DE-A-19939395, WO 00 / 56156, WO 01 / 24634 and WO 01 / 33966. Contents of the invention [0006] It has now been found that the dihydrofuranone derivatives containing formula (I) [0007] [0008] Combinations of active ...
