Embodiment 1、21

[0046] Embodiment 1, the preparation of 21% dicofol compound I emulsifiable concentrate

[0047] According to the formula requirements, add 1 part of dicofol, 20 parts of compound I, 5 parts of Nongru 0201B, 5 parts of Nongru 507#, 2 parts of Nongru 1601#, 8 parts of methanol, and xylene to make up to 100% and add them to the mixing kettle. Stir and mix evenly, and if necessary, heat and dissolve in a hot water bath to obtain 21% dicofol·compound I emulsifiable concentrate.

[0048] It is also possible to replace dicofol with benzafite, bromofen, acetophenone, xiaofentong, dinitrocrotonyl ester, Dinocap-4, Dinocap-6, 4,6-dinitro-o- Cresol, acarid, Thioquinox, fenpyramide, sulfadifen, arsenousoxide, benflusulfonamide, sulfur, pyrimethan, pyrimaben, adiquinone, hydramethazone, cyflumetate, cyfenpyrafen , SYP-10898 and other insecticides / acaricides, forming a new 21% active ingredient B·Compound I emulsifiable concentrate. Embodiment 2, the preparation of 21% benfate compound I...

Embodiment 2

[0048] It is also possible to replace dicofol with benzafite, bromofen, acetophenone, xiaofentong, dinitrocrotonyl ester, Dinocap-4, Dinocap-6, 4,6-dinitro-o- Cresol, acarid, Thioquinox, fenpyramide, sulfadifen, arsenousoxide, benflusulfonamide, sulfur, pyrimethan, pyrimaben, adiquinone, hydramethazone, cyflumetate, cyfenpyrafen , SYP-10898 and other insecticides / acaricides, forming a new 21% active ingredient B·Compound I emulsifiable concentrate. Embodiment 2, the preparation of 21% benfate compound I wettable powder

[0049] According to the formula requirements, mix 1 part of benzamite, 20 parts of compound I, 2 parts of sodium lauryl sulfate, 4 parts of sodium naphtholsulfonic acid formaldehyde condensate, 4 parts of dispersant YUS-WP1, and 5 parts of white carbon black , Light calcium carbonate supplemented to 100% and fully mixed, after being pulverized by an ultra-fine pulverizer, 21% wettable powder of benzamite·compound Ⅰ can be obtained.

[0050] It is also possib...

Embodiment 4

[0054] Example 4, Preparation of 22% bromofen-compound I aqueous emulsion

[0055] According to the formulation requirements, 2 parts of bromofen, 20 parts of compound I, 4 parts of polyoxyethylene (n 20 ) phenylethyl phenol ether oleate, 6 parts of Nongru OX-2681, 2 parts of Nongru 1601#, 8 parts of xylene, and 5 parts of tributyl phosphate were added to the mixing kettle, stirred and mixed to dissolve into a uniform oil Phase, under high-speed stirring, add the remaining amount of water (make up to 100%) into the oil phase to obtain a well-dispersed 22% bromodiclofen·Compound I aqueous emulsion.

[0056] Bromofen can also be used to replace the benzfite, dicofol, acetophenone, Xiaofentong, dinitrocrotol ester, Dinocap-4, Dinocap-6, 4,6-dinitro-o- Cresol, acarid, Thioquinox, fenpyramide, sulfadifen, arsenousoxide, benflusulfonamide, sulfur, pyrimethan, pyrimaben, adiquinone, hydramethazone, cyflumetate, cyfenpyrafen , SYP-10898 and other insecticides / acaricides, forming a n...

Abstract

The invention belongs to the field of insecticides and relates to a synergistic miticidal composition containing two active ingredients A and B, wherein the ratio of the parts by weight of the ingredient A and the ingredient B is (1:100)-(100:1); and the active ingredient A is selected from a compound I shown by a structural formula in the specification, the active ingredient B is selected from an insecticide / acaricide, and the structure of the active ingredient A is as shown in the specification. The composition provided by the invention has the advantages of obvious synergistic effect, capability of delaying resistance and the like, and can be used for controlling various harmful insects.

Description

technical field [0001] The invention belongs to the field of insecticides and relates to a synergistic acaricidal composition. Background technique [0002] Insecticides play an obvious role in controlling agricultural and forestry pests or urban sanitation pests. [0003] Chinese invention patent CN101875633 discloses a pyrazolyl acrylonitrile compound and its use for controlling insect pests and mite infestation, wherein compound 5 (hereinafter referred to as compound Ⅰ) can be used to prevent and control various pests and pest mites, especially for pest mites. prevention effect. . [0004] Insecticides containing a single active ingredient are used continuously in pest control, which can easily cause pests to develop resistance. The insecticides with two active components are mixed in a certain proportion to form a mixed component, which can often improve the control effect, reduce the amount of active ingredients, save costs, and delay the emergence of insecticide res...
