Abstract

The embodiment of the invention discloses a microemulsion with emamectin benzoate being an effective component and relates to the technical field of pesticides. The microemulsion with the emamectin benzoate being the effective component comprises, by mass, 5.7% of the emamectin benzoate, 15-30% of solvent, 10-20% of surfactant, 0.5-5% of synergist, 1-5% of anti-freezing agent, 0.1-2% of stabilizerand water which is added to 100%, wherein the synergist is composed of alkyl polyglycoside and iso-alcohol polyoxyethylene ether according to the weight ratio of 1-3:2-4. By use of the environment-friendly solvent, the microemulsion has the advantages of being stable in performance and remarkable in prevention effect, thereby solving the problems that a solvent adopted in an existing microemulsion is not environmentally friendly and is not safe in use.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of pesticides, in particular to a microemulsion with emamectin benzoate as an active ingredient and a preparation method thereof. Background technique [0002] Emamectin benzoate (abamectin emamectin for short) is white or light yellow crystalline powder, soluble in acetone and ethyl acetate, slightly soluble in water, insoluble in hexane. Is from the fermented product Abamectin B 1 A new type of high-efficiency semi-synthetic antibiotic insecticide has been synthesized. It has the characteristics of ultra-high efficiency, low toxicity (preparation is almost non-toxic), low residue, and pollution-free biological pesticides. It is widely used in the control of various pests on vegetables, fruit trees, cotton and other crops. [0003] Except for a few highly volatile and highly water-soluble pesticides that can be used directly, most of them must be processed into various dosage for...
