Problems solved by technology

However, although the mixture can delay drug resistance, the selection of the two substances cannot be expected to be obtained. At the same time, the insecticide and acaricide compositions containing compound I generally disclosed in the prior art have different emphasis and cannot achieve broad-spectrum , and the effect is quite different

Embodiment 1

[0034] Example 1 Determination of the synergistic effect of the composition containing compound I on Tetranychus cinnabarinus

[0035] Test objects: Tetranychus cinnabarinus Boisduval, adult mites, sensitive strains raised indoors.

[0036] Test conditions: temperature: 24~26℃, relative humidity: 60%, light: L:D=14:10

[0037] Preparation of medicinal liquid: according to different test needs, use an electronic analytical balance to accurately weigh the test samples (different proportioning compositions of the present invention and the original drug), wherein the original drug is dissolved in acetone, and then used 0.1% Tween 80 water according to The experimental design dose is diluted to a certain concentration of the liquid.

[0038] Test method: The potted seedling spraying method was used to determine the activity against adult mites of Tetranychus cinnabarinus. First, 40-60 adult Tetranychus cinnabarinus mites with the same size were placed on the bean seedlings in the...

Embodiment 2

[0050] Example 2 Determination of indoor activity of the composition containing compound I against Tetranychus cinnabarinus

[0051]From the above-mentioned synergistic effect measurement data, it can be seen that the composition of the compound I of the present invention mixed with 8 agents such as chlorpyrifos has obvious synergistic effect on the adult mites of Tetranychus cinnabarinus. Further, compound I and veratridine are used for testing 20:1-1: The composition consisting of 10 was then tested for indoor activity by Sun y-p method.

[0052] Test target: Tetranychus cinnabarinus Boisduval adult mites, sensitive strains raised indoors.

[0053] Preparation of medicinal liquid: According to different test needs, the test samples are accurately weighed with an electronic analytical balance, wherein the original drug is dissolved in acetone, and then diluted with 0.1% Tween 80 water according to the experimental design dose to form a series of drugs with a certain concentra...

Abstract

The invention belongs to the field of insecticidal and acaricidal agents, and relates to an insecticidal and acaricidal composition. The composition contains an active component A and an active component B, and the weight part ratio of the active component A to the active component B is (1: 99)-(99: 1); the active component A is selected from a compound I, and the active component B is selected from organophosphorus, nicotinic acetylcholine receptor (nAChR) agonists, antifeedants, nereistoxin analogs, ryanodine receptor modulators, voltage-dependent sodion channel blockers, aminobutyric acid (GABA) gated chloride channel antagonists, microorganisms or other insecticides (mites); the composition disclosed by the invention has the advantages of obvious synergism, resistance delay and the like, and can be used for preventing and treating various pests.

Description

technical field [0001] The invention belongs to the field of insecticidal and acaricidal agents, and relates to an insecticidal and acaricidal composition. Background technique [0002] Insecticides and acaricides play a significant role in controlling agricultural and forestry pests or urban sanitary pests. [0003] Chinese invention patent CN105541682 discloses a biphenyl compound and its use for controlling insect pests and mites, wherein compound 1 (hereinafter referred to as compound I) can be used to control various pests and mites, and especially has outstanding control effect on mites . [0004] Insecticides and acaricides containing a single active component are used continuously in pest control, which is easy to cause pests to develop drug resistance. By mixing the insecticides and acaricides of two active components into a mixed component, the generation of pest resistance can be delayed. However, although the mixture can delay drug resistance, the choice of th...
