Effect test

Embodiment A

[0342] Myzus persicae test

[0343] Solvent: 7 parts by weight of dimethylformamide

[0344] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0345] To prepare a suitable active compound preparation, 1 part by weight of the active compound is mixed with the stated amount of solvent and emulsifier, and the concentrate is diluted with water containing the emulsifier to the desired concentration.

[0346] Cabbage (Brassica oleracea) leaves severely infested by the green peach aphid (Myzus persicae) are immersed in the active compound preparation of the desired concentration for treatment.

[0347] After the required time, the mortality rate is determined in %. 100% means that all aphids have been killed; 0% means that no aphids have been killed.

[0348] Substitute the determined mortality rate into Colby's formula.

[0349] In this test, for example, the following active compound combinations of the present application showed synergistic activity relative to the active compou...

Embodiment B

[0361] The larvae test of horseradish beetle

[0362] Solvent: 7 parts by weight of dimethylformamide

[0363] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0364] To prepare a suitable active compound preparation, 1 part by weight of the active compound is mixed with the stated amount of solvent and emulsifier, and the concentrate is diluted with water containing the emulsifier to the desired concentration.

[0365] Cabbage (Brassica oleracea) leaves are immersed in the active compound preparation of the desired concentration for treatment, and horseradish beetle (Phaedon cochleariae) larvae are inserted while the leaves are still moist.

[0366] After the required time, the mortality rate is determined in %. 100% means that all beetle larvae have been killed; 0% means that no beetle larvae have been killed. Substitute the determined mortality rate into the Colby formula (see Table 1).

[0367] In this test, the following active compound combinations of the present ap...

Abstract

The invention relates to novel active substance combinations containing an active substance selected form neonicotinoid clothianidin, imidacloprid, thiacloprid, dinotefuran, acetamiprid, nitenpyram and thiamethoxam series and at least one type of active substance selected from a strobilurin fungicide, picoxystrobin, pyraclostrobin, dimoxystrobin, metominostrobin and orysastrobin series. The use of said novel active substance combinations in the form of pesticides and seed dressing agents, methods for controlling pests and protecting seeds and seeds treated by means of the inventive active substance combinations are also disclosed.

Description

[0001] This application is a divisional application of the 200580044370.4 invention patent application entitled "Pesticides based on selected neonicotinoids and methoxyacrylates" filed on December 17, 2005. Technical field [0002] The present invention relates to a new combination of active compounds (combination), which contains the following active compounds: first, an active compound selected from neonicotinoids, and, second, at least one selected from methoxy The active compound of strobilurin fungicides, the combination has surprisingly good insecticidal and fungicidal properties. Background technique [0003] The methoxy acrylate fungicide picoxystrobin (picoxys trobin) of the following formula is known [0004] [0005] It can be used as a fungicide to control plant fungal diseases. Picoxystrobin is described in, for example, EP0278595A2 or The Pesticide Manual of the 13th edition (2003) published by the British Crop Protection Council. [0006] The methoxyacrylate fungicide...
