Abstract

The invention relates to a pesticide preparation and a preparation method thereof, in particular to trifloxystrobin water emulsion and a preparation method thereof. The trifloxystrobin water emulsion comprises the following ingredients in part by mass: 0.5 to 40 parts of trifloxystrobin, 1 to 20 parts of solvent, 1 to 15 parts of emulsifier, 0.1 to 6 parts of thickening agent, 0.2 to 6 parts of antifreeze, 0.1 to 1.5 parts of defoaming agent, 0 to 3 parts of antimicrobial agent, a proper amount of pH value adjusting agent and the balance of deionized water. The trifloxystrobin has a broad-spectrum bactericidal property, has special effects on powdery mildew and leafspot, and has high activity on a rust disease, downy mildew, damping off and apple scab. No or few organic solvent is used, so the manufacturing cost and the using cost are reduced, the toxicity on operators, storage and transportation workers and users in the production, storage, transportation and using processes is reduced, and the trifloxystrobin water emulsion is an environmentally-friendly product with high safety.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a trifloxystrobin aqueous emulsion and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection is getting stronger and they are eager for high-efficiency, low-toxicity, low-residue, and environment-friendly pesticides, pesticide scientists are working day and night to develop new varieties and formulations of high-efficiency, low-toxicity, and environment-friendly pesticides. [0003] For a long time, pesticide emulsifiable concentrate has been one of the main dosage forms in pesticide preparations. Containing a large amount of organic solvents in the emulsifiable concentrate, there are unsafe factors such as easy fire, explosion, toxicity and the disadvantages of polluting the environment. At present, the dosage form of emulsifiable concentrate has been eliminated in our country. Therefore, it is ur...
