Problems solved by technology

So far, the main wall materials used in the preparation of emamectin benzoate slow-release microcapsules at home and abroad are polyurea, polyurethane, polyamide, urea-formaldehyde resin, etc., but the common disadvantage of these wall materials is that they are not easy to degrade in the environment , if it is used for a long time, it will also cause certain pressure on the environment

Abstract

The invention discloses an emamectin benzoate polylactic acid microsphere suspension and a preparation method thereof, and belongs to the field of pesticide preparation. The emamectin benzoate polylactic acid microsphere suspension comprises the following raw materials in mass percentage: 3.0% of emamectin benzoate polylactic acid microspheres, 5.0-7.0% of wetting and dispersing agent, 2.0-3.0% of thickener, 2.5-3.5% of anti-freezing agent, 0.1% of preservative, and water for supplementing to 100%. The preparation method comprises the following steps: weighing emamectin benzoate polylactic acid microspheres, the wetting and dispersing agent, the thickener, the anti-freezing agent, the preservative and water according to the mass percentages of the raw materials; and oscillating and dissolving the raw materials to obtain the emamectin benzoate polylactic acid microsphere suspension with the mass percentage of 3.0%. The emamectin benzoate polylactic acid microsphere suspension is unique in formulation, simple in preparation method, significant in effect and has significant economic and social benefits.

Description

Technical field [0001] The invention is the field of pesticide preparation, which involves a methadosolitin phenyl polyal acid microsphere suspension and its preparation methods. Background technique [0002] With the use of chemical pesticides, the global environment and ecological balance have been severely damaged.The toxicity, residues and environmental pollution of pesticides are very serious in my country. In order to solve this problem, on the one hand, the development of new pesticides with high -efficiency and low toxicity, biodegradation and environmental compatibility should be strengthened. On the other hand Green pesticide preparation.For a long time, pesticide milk oil has always been an important dosage type of pesticide preparations, and milk oil contains a large amount of organic solvents. It has strict requirements for production, transportation and use.These issues have attracted widespread international attention. [0003] Micro -capsule (micro -ball) refers t...
