Problems solved by technology

[0014] Using the above agents alone has the disadvantages of narrow insecticidal spectrum, easy resistance of pests after continuous use, large dosage, relatively high cost, and will aggravate environmental pollution, poor quick-acting or long-lasting effects, etc.
In order to develop a quick-acting and long-lasting effect and reduce the cost of pesticides, on the basis of indoor bioassay screening and field experiments, we screened sulfoxaflor and chitin synthesis inhibitor compounds for binary compounding, which has Obvious synergistic effect, high efficiency and environmental protection Up to now, no relevant compound reports have been found

Embodiment approach

[0023] In the following embodiments, component A is selected from sulfoxaflor, and component B is selected from the chitin synthesis inhibitor compounds buprofezin, imidazoturon, diafenthiuron, hexaflumuron, flufenuron, lufenuron any one of.

[0024] 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:

[0025]

[0026]

[0027] 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 e...

example 1

[0059] (1) Test drug

[0060] 96% sulfoxaflor technical and 94% hexaflumuron technical, all of which are provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0061] (2) Test target

[0062] Cotton bollworm reared for generations indoors, indoor conditions: temperature (26±2)°C. The relative humidity is 70%±5%, and the photoperiod is 16 / 8h (L / D).

[0063] (3) Test method

[0064] In this test, the worm body immersion method was used. Firstly, the mother liquors of sulfoxaflor and hexaflumuron were diluted to 5 concentrations and placed in beakers respectively for later use. Gently sweep the cotton bollworm larvae at the beginning of the third instar with the same physiological state into the worm soaker with a brush, immerse the worm soaker in the medicinal solution, shake it gently, take it out after 5 seconds, and quickly wash the larvae with absorbent paper. Excess liquid medicine around. The treated larvae were placed in an intelligent insect culture room wi...

[0081] (1) Experimental test agent

[0082] 96% of the original drug of sulfoxaflor and 93% of the original drug of buprofezin, all of which are provided by Qingdao Hailier Pharmaceutical Group.

[0083] According to the pre-experiment setting, the total active ingredients of the two are 20%, and the set ratio is m (sulfoxaflor): m (buprofezin) respectively 5: 15; 7: 13; 9: 11; 11: 9; 13:7.

[0084] (2) Test target

[0085] Wheat aphids were collected from the field population of the wheat experimental field of Qingdao Agricultural University, and wingless adult aphids of the same individual size were selected for testing.

[0086] Experimental method is the same as activity determination example 1

Abstract

The invention relates to a high-performance and friendly-environmental pesticide compound composition. The pesticide compound composition is characterized in that: effective components of the pesticide compound composition comprise a clothianidin amide compound and a benzoylurea compound, wherein a weight percent of the clothianidin amide compound to the benzoylurea compound is 1-80:80-1, preferably 1-40:40-1; a total mass percentage content of the effective components in pesticide compound composition is 1%-90%, preferably 10-50%, and the balance is agrochemically- workable and agrochemically-acceptable adjuvants; the pesticide compound composition can be prepared in an aqueous emulsion, a microemulsion, a cream, a suspension, a wettable powder or a water dispersible granule; the pesticide compound composition adopts the clothianidin amide and the neonicotine insecticide as the effective components for controlling homopteran pests and thysanoptera pests, such as rice leaf roller, diamond-back moth, prodenia litura, cotton bollworm or spodoptera exigua, thrips and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition which uses sulfoxaflor and a chitin synthesis inhibitor compound as active ingredients for binary compounding. 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 h...
