preparation example Construction

[0031] The present invention also provides the preparation method of the sulfoxaflor hot fog agent provided by the above scheme, comprising the following steps:

[0032] After dissolving sulfoxaflor with a solvent, the obtained sulfoxaflor solution is mixed with a surfactant, a penetrating agent and triphenyl phosphate to obtain a sulfoxaflor hot spray.

[0033] In the present invention, the dissolving and mixing are preferably carried out under stirring conditions, and the present invention has no special limitation on the stirring conditions, and the conventional stirring conditions used by those skilled in the art can be used.

[0034] The present invention also provides the application of the sulfoxaflor thermal mist provided by the above technical solution in the prevention and control of crop pests, specifically Spodoptera litura, citrus psyllid, sugarcane aphid, corn aphid and tobacco thrips.

[0035] In the present invention, there is no special limitation on the metho...

Embodiment 1

[0038] Sulfoxaflor 0.5kg, Azone 1kg, Castor Oil Polyoxyethylene Ether 2.5kg, Calcium Dodecyl Benzene Sulfonate 0.5kg, Triphenyl Phosphate 1kg, Acetophenone 10kg, Methylnaphthalene supplemented to 100kg.

[0039] Preparation method: In a container with stirring, first dissolve sulfoxaflor with solvent acetophenone and methylnaphthalene, then add surfactant castor oil polyoxyethylene ether, calcium dodecylbenzenesulfonate , the penetrating agent azone and triphenyl phosphate are stirred and mixed to obtain the hot spray of sulfoxaflor.

Embodiment 2

[0041] Sulfoxaflor 1kg, Azone 2kg, Fatty Alcohol Polyoxyethylene Ether 6kg, Calcium Dodecylbenzene Sulfonate 3kg, Triphenyl Phosphate 4kg, N-Methylpyrrolidone 5kg, Soybean Oil 15kg, Methylnaphthalene Supplement to 100kg.

[0042] The preparation of this example was prepared according to the same preparation method as in Example 1.

Abstract

The invention provides sulfoxaflor hot fogging concentrate. The sulfoxaflor hot fogging concentrate is prepared from the following components in percentage by weight: 0.5 percent to 12 percent of sulfoxaflor, 3 percent to 13 percent of a surfactant, 1 percent to 5 percent of a penetrating agent, 1 percent to 10 percent of triphenyl phosphate and the balance of an organic solvent, wherein the organic solvent is one or more of an aromatic hydrocarbon solvent, a vegetable oil solvent and a polar solvent. By adopting the sulfoxaflor hot fogging concentrate provided by the invention, the prevention and control effect is higher than that of micro-emulsion, emulsion, water dispersible granules, missible oil, wettable powder and a suspending agent and the sustainability is longer. The effect of the sulfoxaflor hot fogging concentrate provided by the embodiment of the invention shows that after the sulfoxaflor hot fogging concentrate provided by the invention is used for 3 days, the prevention and control effect on insect pests of crops reaches 86 percent or more and can reach 94 percent at maximum; after the sulfoxaflor hot fogging concentrate is used for 15 days, the prevention and control effect can still reach 80 percent or more and can reach 88 percent at maximum.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a sulfoxaflor thermal mist agent and a preparation method and application thereof. Background technique [0002] Sulfoxaflor belongs to the class of sulfoximide insecticides that act on the nervous system of insects. Sulfoxaflor is suitable for controlling all piercing-sucking mouthparts pests such as cotton ligud bugs, aphids, whiteflies, planthoppers and scale insects. At present, the dosage forms of sulfoxaflor on the market are mainly suspension concentrates, emulsifiable concentrates, wettable powders, water emulsions and water dispersible granules, which are sprayed after dilution with water, but the control effect achieved by these dosage forms is not high. Contents of the invention [0003] In view of this, the object of the present invention is to provide a sulfoxaflor thermal mist, which can improve the control effect on insect pests, in view of the de...
