Abstract

The invention discloses a flonicamid water emulsion and a method for preparing the flonicamid water emulsion. The flonicamid water emulsion comprises the following components in percent by weight: 1-15% of flonicamid, 3-25% of solvent, 4-15% of emulsifying agent, 0.5-2% of dispersing agent, 1-5% of stabilizing agent, 1-5% of anti-freezing agent and the balance of deionized water. The method for preparing the flonicamid water emulsion comprises the following steps: dissolving the flonicamid into the solvent, adding the emulsifying agent, the stabilizing agent and the dispersing agent to prepare an oil phase, mixing the anti-freezing agent with the deionized water to prepare a water phase, and adding the oil phase into the water phase or the water phase into the oil phase slowly under the high shearing condition to prepare the flonicamid water emulsion. The flonicamid water emulsion is a safe and environmentally friendly agricultural pesticide with a good effect.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a flonicamid aqueous emulsion and a preparation method thereof. Background technique [0002] Flunicamid is effective against various piercing-sucking mouthparts pests and has good penetration. It can penetrate from roots to stems and leaves, but the penetration from leaves to stems and roots is relatively weak. The drug works by hindering the sucking action of the pests, and the pests stop sucking soon after ingesting the drug, and finally starve to death. Due to the unique mechanism of action and high biological activity of flonicamid, as well as its high safety to humans, animals and the environment, and its effectiveness against other insecticide-resistant pests, it has great room for development . [0003] Modern pesticide dosage forms are developing towards water-based, ultra-micronized, powder-free and controlled release, that is, water-based p...
