The invention discloses a hexazinone-containing herbicide and a preparation method thereof, and belongs to the technical field of pesticides. The preparation method comprises the following steps: S1, preparing PEI / CS; and S2, uniformly mixing Tween-80 with a PEI / CS solution, dispersing hexazinone in DMF for ultrasonic dissolution, slowly dropwise adding the hexazinone solution into the PEI / CS solution under a magnetic stirring condition, carrying out a reaction for 30 min to obtain PEI / CS / hexazinone, dropwise adding a 2-hydroxy-4-methoxybenzophenone-5-sodium sulfonate solution into the PEI / CS / hexazinone, carrying out a stirring reaction for 30 min, and carrying out centrifugation, washing and drying to obtain the hexazinone-containing herbicide. The final product obtained by the method has high load rate, slow release stability and photodegradation resistance, the preparation efficiency is high, and the process is simple and controllable.

The present application relates to a composition containing pyrethroid insecticide and its application. The composition has synergistic effect of cycloxaprid and pyrethroid insecticide, which can improve the effect of pest control, reduce the amount of pesticide application, reduce the frequency of use, and reduce the cost of use.

The present application relates to the composition containing pyrazole carboxamide compound and its application. The composition contains cycloxaprid and compound II. The cycloxaprid has synergistic effect with compound II, which can improve the pest control effect, reduce the application amount, reduce the use frequency, and reduce the use cost.

The invention relates to the technical field of pesticide preparations, in particular to a cycloxaprid flying prevention preparation and a preparation method thereof.The cycloxaprid flying prevention preparation is at least prepared from, by mass, 10-30% of cycloxaprid active compound, 2-5% of wetting agent, 10-20% of dispersing grinding aid, 5-10% of stabilizer and the balance filler. The use effect and compound characteristics of cycloxaprid are fully exerted, so that the particle size of the product meets the flight control requirement, the actual agricultural production and use are met, and the pesticide utilization rate is increased.

The application belongs to the technical field of herbicides, and provides a preparation method of the herbicide cycloxaprid, which comprises the following steps: 1, mixing and stirring monocyanamide and ethyl chloroformate, cooling to 0-2 DEG C, adding liquid alkali dropwise, controlling pH and temperature, and carrying out incubation reaction to obtain a product GH520-1; 2, adding dimethyl sulfate and benzyl triethylammonium chloride to the product GH520-1, carrying out warming reaction, and after the reaction is completed, standing and layering to obtain a product GH520-2; 3, adding dimethylamine hydrochloride and liquid alkali to the product GH520-2, supplementing toluene, carrying out warming reaction, cooling to room temperature, standing and layering to obtain a product GH520-3; 4, dissolving the product GH520-3 in toluene, adding cyclohexyl isocyanate, and controlling the reaction temperature to obtain a product GH520-4; and 5, adding sodium methoxide and dimethylamine aqueous solution to the product GH520-4, controlling the reaction temperature, and obtaining a product GH520.
