Embodiment approach

[0015] In the following technical solutions, component A is selected from sulfenalazine, and component B is selected from neonicotinoid insecticides imidacloprid, acetamiprid, nitenpyram, thiamethoxam, thiacloprid, clothianidin , any one of dinotefuran.

[0016] One of the technical solutions of the present invention, the insecticidal composition is an aqueous emulsion, and the weight percent of the component is:

[0017]

[0018] The specific production steps of the water emulsion are as follows: first, add the original drug A and B, the solvent, the emulsifier and the cosolvent together to dissolve into a uniform oil phase; add part of the water, antifreeze, antimicrobial agent and other other The pesticide adjuvants 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 reaching the phase inversion point, turn on the shearing machine for high-speed shearing, and add the r...

[0048] (1) Test drug

[0049] 96% sulfenalazine TC, 95% imidacloprid TC, all the above TCs are provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0050] First dissolve the original drug with acetone, according to the results of the preliminary experiment, the appropriate amount of the two original drugs is formulated into 5 different ratios, and then each treatment is diluted with acetone into 5 series of concentration gradients for use. The ratios of the five active ingredients in different proportions of sulfenalazine and imidacloprid are respectively 8:27; 10:25; 12:23; 14:21;

[0051] (2) Test target

[0052] Wheat aphids were collected from the field population of the wheat experimental field of Qingdao Agricultural University. During the experiment, wingless adult aphids of the same size were selected for testing.

[0073] 96% sulfenalazine original drug, 99% acetamiprid original drug, the above-mentioned original drugs are all provided by Qingdao Hailier Pharmaceutical Group.

[0074] (2) Test target

[0075] Citrus aphids were collected from the Jiangxi citrus orchard population, and the wingless adult aphids with the same size were selected for the experiment.

Abstract

The invention relates to an insecticidal composition in the field of pesticide compounding, comprising the effective components, namely sufoxaflor and neonicotine insecticides, wherein the weight percentage ratio of the two effective components is (1-80):(80-1), preferably (5-50):(60-5); the total mass percentage content of the effective components in the insecticidal composition is 1-90 percent, preferably 5-60 percent; and the rest in the insecticidal composition is auxiliary components which are allowed to be used and are acceptable in the pesticide. By adopting the known method, the insecticidal composition can be prepared into water emulsion, microemulsion, emulsifiable solution, suspending agent, wettable powder and water dispersible granules; and with the sufoxaflor and the neonicotine insecticides as the effective components, the insecticidal composition can be used for controlling plant louses, whiteflies, plant hoppers, scale insects, capsid bugs on cotton, cicada, spittlebug, leafhoppers, thorn bug, fulgora, psyllid and other homoptera pests.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a two-component insecticidal composition comprising sulfluramid and a neonicotinoid compound as active ingredients. 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] Sulfluramid is a sulfonimide insecticide that acts on a unique binding site in the choline receptor to exert its insecticidal function. It can be absorbed into plants through leaves, stems and roots. Sulfluramid is suitable for the control of cotton lycine bugs, aphids, whiteflies, planthoppers and scale insects, etc. It is highly efficient, fast and has a long residual effect period, and can effectively control nicotine, pyrethroids, organophosphorus and amino acids Sap-sucking pests that are resistant to formate pesticides. It has t...
