Embodiment 1、21

[0044] Embodiment 1, the preparation of 21% carbosulfan compound I emulsifiable concentrate

[0045] According to the formula requirements, add 1 part of carbosulfan, 20 parts of compound Ⅰ, 4 parts of agricultural milk 0201B, 6 parts of agricultural milk 2201#, 2 parts of agricultural milk 500#, 5 parts of dimethylformamide, and xylene to supplement Add it to 100% into the mixing kettle, stir and mix evenly, and if necessary, heat and dissolve in a hot water bath to obtain 21% carbosulfan compound I emulsifiable concentrate.

[0046] Carbosulfan can also be substituted for one of the carbamate insecticides described in the cost specification to form a new 21% carbamate insecticide Compound I EC.

Embodiment 2、44

[0047] Embodiment 2, the preparation of 44% carbofuran compound I wettable powder

[0048] According to the formulation requirements, 40 parts of carbofuran, 4 parts of compound I, 2 parts of sodium lauryl sulfate, 4 parts of sodium salt of alkylnaphthalene sulfonic acid condensation polymer, 4 parts of polycarboxylate dispersant GY-D800, 5 parts of white carbon black and light calcium carbonate are supplemented to 100% and fully mixed, and pulverized by an ultra-fine pulverizer to obtain a 44% carbofuran compound I wettable powder.

[0049] Carbofuran can also be substituted for one of the carbamate insecticides described in the cost specification to form a new 21% carbamate insecticide Compound I wettable powder.

Embodiment 3

[0050] Example 3, the preparation of 40% pyrabicarb·compound I wettable powder (1:1)

[0051] According to the formula requirements, mix 20 parts of pyrabicarb, 20 parts of compound I, 1 part of Morwet EFW, 5 parts of alkylnaphthalene sulfonate formaldehyde condensate, 3 parts of sodium dibutylnaphthalene sulfonate, 2 parts of detergent LS, 5 parts of white carbon black and diatomaceous earth are supplemented to 100% and fully mixed, and pulverized by an ultra-fine pulverizer to obtain 40% azoles pirimicarb · compound I wettable powder.

[0052] It is also possible to replace one of the carbamate insecticides described in the cost specification with pyraximecarb to form a new 21% carbamate insecticide·compound I wettable powder.

Abstract

The invention belongs to the field of insecticides, and relates to an insecticidal and acaricidal composition containing a carbamate insecticide. The composition contains an active component A and an active component B, a weight part ratio of the component A to the component B is 1:99-99:1, the active component A is a compound I represented by a structural formula shown in the invention, and the active component B is selected from carbamate insecticides. The composition has the advantages of obvious synergy and resistance delaying, and can be used for controlling various insects.

Description

technical field [0001] The invention belongs to the field of insecticides, and relates to an insecticidal and acaricidal composition containing carbamate insecticides. 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 ...
