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 pyrethroid 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 pyrethroid 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...

Examples

Embodiment 1、20

[0045] Embodiment 1, the preparation of 20% fenpropathrin compound I emulsifiable concentrate

[0046] According to the formula requirements, add 2 parts of fenpropathrin, 18 parts of compound I, 6 parts of Nongru 0201B, 4 parts of Nongru 507#, 2 parts of Nongru 1601#, and add xylene to 100% into the mixing kettle, and stir Mix well, and if necessary, heat and dissolve in a hot water bath to obtain 20% fenpropathrin·compound I emulsifiable concentrate.

[0047] It is also possible to replace fenpropathrin with one of the pyrethroid insecticides described in the cost manual to form a new 20% pyrethroid compound I emulsifiable concentrate.
