Embodiment 1

[0027] Example 1 Synergistic Determination of Compositions Containing Compound I on Tetranychus cinnabarinus

[0028] Test object: Tetranychus cinnabarinus Boisduval, adult mite, a sensitive strain raised indoors.

[0029] Test conditions: temperature: 24~26℃, relative humidity: 60%, light: L:D=14:10

[0030] Preparation of medicinal solution: According to the needs of different tests, the samples to be tested were accurately weighed with an electronic analytical balance, wherein the original drug was dissolved in acetone, and then diluted with 0.1% Tween 80 water to form a medicinal solution with a certain concentration according to the designed dose of the test.

[0031] Test method: Potted seedling spray method was used to measure the activity of Tetranychus cinnabarinus adults. Firstly, 40-60 adult mites of Tetranychus cinnabarinus with the same size were connected to the bean seedlings (leaving a true leaf) in the first pair of true leaf flattening stage, and counted bas...

Embodiment 2

[0040] Example 2 The composition containing compound I is measured against the indoor activity of Tetranychus cinnabarinus

[0041] From the above synergistic effect measurement data, it can be seen that the composition of the compound I of the present invention mixed with three agents such as ethifenapyr has obvious synergistic effect on adult mites of Tetranychus cinnabarinus. The combination of 5:1-1:5 of cyflumet and cyflumet was used for indoor activity determination by Sun y-p method.

[0042] Test target: Tetranychus cinnabarinus (boisduval) adult mite, a sensitive strain of indoor breeding.

[0043] Preparation of medicinal solution: According to the needs of different tests, use an electronic analytical balance to accurately weigh the samples to be tested. Among them, the original drug is dissolved in acetone, and then diluted with 0.1% Tween 80 water according to the test design dose to form a series of drugs with a certain concentration gradient. liquid.

Abstract

The invention belongs to the field of insecticidal and acaricidal agents, and relates to a synergistic insecticidal and acaricidal composition. The composition contains an active component A and an active component B, and the weight part ratio of the component A to the component B is 1: 99-99: 1, wherein the active component A is selected from a compound I shown in the structural formula as shownin the specification, the active component B is selected from mitochondrial transfer complex (II)inhibitor insecticides / acaricides, and the structure of the active component A is as shown in the specification; the composition provided by the invention has the advantages of obvious synergy, resistance delaying and the like, and can be used for preventing and treating various pests.

Description

technical field [0001] The invention belongs to the field of insecticide and acaricide, and relates to a synergistic insecticide and acaricide composition. Background technique [0002] Insecticides and acaricides have obvious effects in controlling agricultural and forestry pests or urban sanitation pests. [0003] Chinese invention patent CN105541682 discloses a biphenyl compound and its use for controlling insect pests and mite infestation, wherein compound 1 (hereinafter referred to as compound Ⅰ) can be used to prevent and control various pests and harmful mites, and has an outstanding control effect on harmful mites in particular . [0004] Insecticides and acaricides containing a single active ingredient are used continuously in pest control, which can easily cause pests to develop resistance. The insecticides and acaricides with two active components are mixed in a certain proportion to form a mixed component, which can often improve the control effect, reduce the ...
