Abstract
The invention relates to a pymetrozine-azone suspension emulsion and a preparation method thereof. The pymetrozine-azone suspension emulsion comprises the following components in percentage by weight: 1-50% of pymetrozine, 1-20% of azone, 1-15% of solvent, 1-10% of emulsifier, 1-10% of wetting agent, 0.1-2% of thickening agent, 1-10% of antifreezing agent, 0.1-1% of defoamer, 0.1-0.5% of preservative, 0.1-1% of pH regulator, and the balance of de-ionized water. The azone is dissolved in a solvent and then the emulsifier and the de-ionized water are orderly added to the solution to obtain azone emulsion in water. After the pymetrozine, the wetting agent, the deformer, the antifreezing agent and the left de-ionized water are formed into grains, the azone emulsion in water, the thickening agent and the pH regulator are added for blending and shearing.
