Problems solved by technology

In addition, although lambda-cyhalothrin has a good inhibitory effect on mites, and it can effectively inhibit the increase in the number of mites when used in the early stage of mites, but when mites have occurred in large numbers, the number cannot be controlled. Therefore, it can only be used for the treatment of both insects and mites, and cannot be used for special acaricides

Embodiment 1

[0024] An insecticidal composition containing imidacloprid and lambda-cyhalothrin is composed of the following pharmaceutical active ingredients and excipients in weight percentage: the total content of imidacloprid and lambda-cyhalothrin is 8%, polyoxyethylene-polyoxy Propylene block copolymer 3%, sodium dodecylbenzene sulfonate 8%, (azone and agricultural milk 1601 mixture with a mass ratio of 1:1~2) 2%, (mass ratio 1:2~3:4~ 6 mixture of cornstarch, attapulgite and diatomaceous earth) 79%. Wherein, the weight ratio of imidacloprid and lambda-cyhalothrin is 1:1.

[0025] The dosage form is water-dispersible powder. Preparation method: mix imidacloprid, lambda-cyhalothrin, dispersant, wetting agent, penetrant, and inert filler, stir evenly, and after fully drying, pulverize with an airflow mill, the fine powder has a particle size of 6 ~10μm, get it by sieving.

Embodiment 2

[0027] An insecticidal composition containing imidacloprid and lambda-cyhalothrin is composed of the following pharmaceutical active ingredients and excipients in weight percentage: the total content of imidacloprid and lambda-cyhalothrin is 89%, polyoxyethylene-polyoxy Propylene block copolymer 1%, fatty alcohol polyoxyethylene ether sodium sulfate 1%, (azone and Nongru 1601 mixture with a mass ratio of 1:1~2) 1%, (mass ratio 1:2~3:4~ 6 mixture of cornstarch, attapulgite and diatomaceous earth) 8%. Wherein, the weight ratio of imidacloprid and lambda-cyhalothrin is 6:1.

[0028] The dosage form is a water-dispersible powder, and the preparation method is the same as in Example 1.

Embodiment 3

[0030] An insecticidal composition containing imidacloprid and lambda-cyhalothrin is composed of the following pharmaceutical active ingredients and excipients in weight percentage: the total content of imidacloprid and lambda-cyhalothrin is 80%, polyoxyethylene-polyoxy Propylene block copolymer 2%, sodium dodecylbenzene sulfonate 5%, (azone and Nongru 1601 mixture with mass ratio 1:1~2) 1%, (mass ratio 1:2~3:4~ 6 mixture of cornstarch, attapulgite and diatomaceous earth) 12%. Wherein, the weight ratio of imidacloprid and lambda-cyhalothrin is 2:1.

[0031] The dosage form is a water-dispersible powder, and the preparation method is the same as in Example 1.

Abstract

The invention discloses a pesticidal composition containing imidacloprid and lambda-cyhalothrin, which is prepared from the following chemical active ingredients and auxiliary material in percentage by weight: 5 to 90 percent of imidacloprid and lambda-cyhalothrin in total content, 1 to 8 percent of dispersant, 1 to 8 percent of wetting agent, 1 to 2 percent of penetrant and the balance of inert filler, and the weight ratio of imidacloprid to lambda-cyhalothrin is (1 to 6):1. The invention compounds imidacloprid and lambda-cyhalothrin to prepare water-dispersible powder in water; imidacloprid and lambda-cyhalothrin have higher joint toxicity on hemiptera, diptera and lepidoptera pests, such as aphids, tetranychidae and prodenia litura, under certain proportion, and also have a mite inhibition and killing effect, and when tetranychidae appear in a large quantity, imidacloprid and lambda-cyhalothrin also have a good killing effect; furthermore, the applicable temperature range is wide, and the pesticidal composition does not have special requirement on environmental temperature.

Description

technical field [0001] The invention belongs to the technical field of chemical pesticides and relates to an insecticidal composition, in particular to an insecticidal composition containing imidacloprid and lambda-cyhalothrin. Background technique [0002] Imidacloprid is a nitromethylene systemic insecticide with broad-spectrum, high efficiency, low toxicity, and low residue. It is not easy for pests to develop resistance, and it is safe for humans, animals, plants, and natural enemies. It also has contact and stomach toxicity. And systemic and other multiple effects. The product is quick-acting, and has a high control effect one day after application, and the residual period is as long as about 25 days. It is mainly used to control piercing-sucking mouthpart pests, such as aphids, planthoppers, whiteflies, leafhoppers, thrips; certain pests of Coleoptera, Diptera and Lepidoptera, such as rice weevil, rice negative mud Insects, leaf miners, etc. are also effective. It c...
