Embodiment approach

[0015] Component A is selected from sulfoxaflor, and component B is selected from any one of bifenthrin, lambda-cypermethrin, cypermethrin, lambda-cyfluthrin, lambda-cyhalothrin, fenpropathrin and deltamethrin .

[0016] In one of the technical solutions of the present invention, the insecticidal composition is an emulsion in water, and the weight percentage of the components is:

[0017]

[0018] The specific production steps of the emulsion in water are as follows: first, the original medicine A and B, solvent, emulsifier, and cosolvent are added together to dissolve into a uniform oil phase; Pesticide auxiliaries are mixed together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearer for high-speed shearing, and add the remaining water , cut for about half an hour to form an oil-in-water emulsion. A water emulsion of the composit...

[0048] Synergistic effect test of compounding sulfoxaflor and bifenthrin.

[0049] The specific method is:

[0050] (1) Test drug

[0051] 96% of the technical sulfoxaflor and 94% of the technical bifenthrin are provided by the R&D Center of Qingdao Hailier Pharmaceutical Group.

[0052] (2) Test target

[0053] The tea leafhopper was collected from Chashan, Jiangxi. During the experiment, the larvae of the tea leafhopper with the same individual size were selected for testing.

[0054] (3) Test method

[0055] In this test, the worm body immersion method was used. Firstly, the mother liquors of sulfoxaflor and bifenthrin were diluted to 5 concentrations, and placed in beakers for later use. Use a brush to gently sweep the tea leafhopper larvae in the same physiological state into the insect soaker, immerse the insect soaker in the liquid medicine, shake gently, take it out after 5 seconds, and quickly wash dry the insect body and the surrounding ground with absorbent pap...

[0072] (1) Experimental test agent

[0073] 96% sulfoxaflor and 95% beta-cypermethrin are provided by Qingdao Hailier Pharmaceutical Group.

[0074] (2) Test target

[0075] Cabbage aphids were collected from the cabbage orchard population in Jiaonan, and wingless adult aphids of the same individual size were selected for testing.

[0076] Experimental method is the same as activity determination example 1

[0077] (3) Toxicity test results and analysis:

[0079]

[0080]

[0081] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, and the synergistic effect of sulfoxaflor: beta-cypermethrin at 10:6 is the most obvious , the co-toxicity coefficient was 151.90, followed by sulfoxaflor: beta-cypermethrin 12:4, the co-toxicity coefficient was 145.3...

Abstract

The invention relates to an insecticidal composition and belongs to the field of pesticide compounding. An insecticide comprises active ingredients of Sulfoxaflor and pyrethroid, wherein the weight percentage ratio of the two active ingredients is (1-80):(50-0.1), and preferably, the weight percentage ratio is (5-45):(25-0.1); the total mass percentage of the active ingredients of the insecticidal composition is 1 to 75 percent and preferably, the total mass percentage is 3 to 40 percent; and the insecticidal composition also comprises auxiliary ingredients which are applicable and acceptable in pesticides. The insecticidal composition can be prepared into emulsifiable solution, microemulsion, water emulsion, a suspending agent, water dispersible granules and wettable powder by the known method. The insecticidal composition comprising the active ingredients of the Sulfoxaflor and the pyrethroid has remarkable effects of preventing and controlling homoptera piercing and sucking type insects such as delphacidae, aphid, whitefly, leafhopper, Icerya purchasi and the like, Lepidoptera insects such as Plutella xylostella, Spodoptera exigua, prodenia litura, Heliothis armigera, Chilo suppressalis, mealybug and the like, and Hemiptera Miridae insects such as cotton capsid bug and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing two-component compounding of sulfoxaflor and pyrethroid compounds. Background technique [0002] Sulfoxaflor, its chemical name: [1-6-(trifluoromethyl)pyridin-3-yl]ethyl]-λ4-mercaptocyanamide; molecular formula: C 10 h 10 f 3 N 3 OS, the structural formula is: [0003] [0004] Sulfoxaflor is a sulfonylimide insecticide that acts on a unique binding site in the choline receptor to exert insecticidal function. It can be absorbed into plants through leaves, stems and roots. Sulfoxaflor is suitable for the control of cotton bugs, aphids, whiteflies, planthoppers and scale insects, etc.; it is efficient, fast and has a long residual effect, and can effectively control neonicotinoids, pyrethroids, organophosphorus and amino acids. Formate pesticides produce resistant sap-sucking pests. It has the advantages of fast onset o...
