Embodiment 1

[0302] Solanum Rhizoctonia test (in vitro) / microtiter plate

[0303] Potato dextrose broth (PDB) was used as the liquid test medium in the microtiter plate for micro test. The active compound is used as an industrial grade active ingredient dissolved in acetone. A suspension of mycelium of Rhizoctonia solani is used for inoculation. After inoculating in the dark and shaking (10 Hz) for 7 days, the transparency of each filled cavity of the microtiter plate was measured by a spectrophotometer.

[0304] Here, 0% means the efficacy corresponding to the growth condition of the control group, and the efficacy of 100% means that no fungal growth is observed.

[0305] The following table clearly shows that the measured activity of the active compound combination of the present invention is greater than the calculated activity, that is, there is a synergistic effect.

Embodiment 2

[0311] Sclerotium rotundus test (in vitro) / microtiter plate

[0312] Potato dextrose broth (PDB) was used as the liquid test medium in the microtiter plate for micro test. The active compound is used as an industrial grade active ingredient dissolved in methanol. A spore suspension of P. rotundus was used for inoculation. After inoculation in the dark and shaking (10 Hz) for 5 days, the transparency of each filled cavity of the microtiter plate was measured by means of a spectrophotometer.

[0313] Here, 0% means the efficacy corresponding to the growth condition of the control group, and the efficacy of 100% means that no fungal growth is observed.

[0314] The following table clearly shows that the measured activity of the active compound combination of the present invention is greater than the calculated activity, that is, it exists in a synergistic effect.

Embodiment 3

[0320] The larvae test of horseradish beetle

[0321] Solvent: 7 parts by weight of dimethylformamide

[0322] Emulsifier: 2 parts by weight of alkyl aryl polyglycol ether

[0323] 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.

[0324] Chinese cabbage leaves (Brassica oleracea) are treated by spraying with a preparation of active compound of the desired concentration, and inoculated with larvae of the horseradish leaf beetle (Hormania oleracea) while the leaves are still moist.

[0325] After the required period of time, the kill rate is determined in %. Here, 100% means that all beetle larvae have been killed; 0% means that no beetle larvae have been killed. The determined kill rate was calculated using Colby's formula.

[0326] In this test, the following active compound combinations...

Abstract

The present invention relates to novel synergistic active ingredient combinations composed firstly of the known carboxamide penflufen and secondly of renaxypyr and/or sulfoxaflor, these combinations being extremely suitable for controlling unwanted animal pests such as insects or acarids and also unwanted phytopathogenic fungi.

Description

[0001] This application is a divisional application of the invention patent application whose application date is June 27, 2011, the application number is 201180041449.7, and the invention title is "a synergistic active ingredient combination containing fluconazole". Technical field [0002] The present invention relates to a new combination of active compounds, which is composed of the known carbonamide penflufen (penflufen) and known compounds with insecticidal activity, the combination is very suitable for controlling unwanted animal pests Such as insects or mites and unwanted phytopathogenic fungi. Background technique [0003] Known carboxamide N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide (fluconazole ) Has bactericidal properties: for example known from WO03 / 010149. The activity of the compound is good; however, at low application rates, it is sometimes unsatisfactory. [0004] The active compounds chlorantraniliprole (Rynaxypyr (chlorantra...
