Embodiment 1

[0051] Embodiment 1: 16.2% chlorpyrifos·beta-cyfluthrin suspension concentrate (1:80)

[0052] Chlorpyrifos 0.2%, Beta-cyfluthrin 16%, Alkylphenol Polyoxyethylene Phosphate 4%, Polyoxyethylene Polyoxypropylene Ether Block Copolymer 3%, Ethylene Glycol 5%, Xanthan Gum 0.15%, Organic Silicone defoamer 0.1%, Cathone 0.5%, water to make up to 100%.

[0053] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and you can prepare 16.2% chlorpyrifos·beta-cyfluthrin suspension agent.

Embodiment 2

[0057] Example 2: 41% chlorpyrifos·beta-cyfluthrin water dispersible granule (1:40)

[0058] Chlorpyrifos 1%, Beta-cyfluthrin 40%, Sodium Lauryl Sulfate 1%, Sodium Lignosulfonate 6%, Starch 5%, and Kaolin Clay make up 100%.

[0059] Preparation method: Mix the original drug, additives and fillers uniformly, then perform airflow crushing, wet granulation and drying to prepare 41% chlorpyrifos·beta-cyfluthrin water-dispersible granules.

Embodiment 3

[0063] Embodiment 3: 22% chlorpyrifos·beta-cyfluthrin microemulsion (1:10)

[0064] Chlorpyrifos 2%, Beta-cyfluthrin 20%, Calcium dodecylbenzene sulfonate 4%, Styrylphenol polyoxyethylene ether 8%, Castor oil polyoxyethylene ether 3%, Cyclohexanone 15%, Trimethylbenzene 10% %, water makes up 100%.

[0065] Preparation method: Dissolve the original drug in a solvent, add an emulsifier and mix evenly, then add water and stir until a clear and transparent liquid is formed to obtain 22% chlorpyrifos·beta-cyfluthrin microemulsion.

Abstract

The invention discloses an insecticidal composition and an application thereof, and relates to the technical field of combination of pesticide. The insecticidal composition comprises an effective component A and an effective component B, the effective component A adopts chlorpyrifos, and the effective component B adopts beta-cyfluthrin, wherein the weight ratio of the effective component A of the chlorpyrifos to the effective component B of the beta-cyfluthrin is 1:80 to 80:1. According to the combination agent, dosing is reasonable, a significant synergistic effect is achieved, the effects especially on lepidoptera such as green fruit worms, tortricid and conopomorpha sinensis bradley and soil insects such as black cutworms, grubs, wireworms and fly maggots are excellent, the application amount of each single dosage can be effectively reduced, the purposes of delaying pesticide resistance and reducing the cost are achieved, and significant application and promotion value is achieved.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition containing active ingredients chlorpyrifos and beta-cyfluthrin and its application, and belongs to the technical field of pesticide compounding. Background technique [0002] In the actual process of agricultural production, chemical control is still the most effective means of controlling pests, but due to the continuous and large-scale use of chemical insecticides, the problem of pest resistance has become increasingly prominent. Moreover, the pests that are prone to resistance to pesticides are usually those with large reproduction numbers and obvious overlapping generations. The compounding of ingredients of different varieties is one of the effective means of integrated management of resistant pests.
