Abstract

The invention belongs to the field of agricultural insecticides and particularly relates to a nanometer micro-emulsion containing acetamiprid and pyridaben and a preparation method and application of the nanometer micro-emulsion. The nanometer micro-emulsion is prepared from the following raw materials in percentages by weight: acetamiprid, pyridaben, 1-2% of a carrier, 8-25% of a surfactant, 5-30% of a solvent, 1-2% of a cosolvent and the balance of water, wherein the ratio of the acetamiprid to thepyridaben is (20:1) to (1:30) and the total content of the acetamiprid and the pyridaben accounts for 5-50%. The prepared nanometer micro-emulsion containing the acetamiprid and the pyridaben is basically spherical, uniform in particle size, monodispersed, non-sticky and high in dispersibility and bioavailability, and the technology gap of the acetamiprid-pyridaben nanometer micro-emulsion is filled. Due to the nano-scale particle sizes, a sample is more stable and higher in infiltration capacity; and meanwhile, the dosage of an emulsifier and a polar solvent is greatly reduced, the cost is reduced and the compatibility with the environment is further increased. The nanometer micro-emulsion is wide in application range, is mainly used for controlling flea beetles on crops, and can be used for controlling phloem-sucking pests on the crops, such as vegetables and fruit trees.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides, and in particular relates to a nano-microemulsion containing acetamiprid and pyridaben and its preparation method and application. Background technique [0002] Nanotechnology is widely used in agriculture. Using nanotechnology to make traditional biological pesticides into nanoparticle preparations can improve the stability of biological pesticides and increase the control efficiency. Because the active ingredients of the drug are encapsulated in nanoparticles, avoiding direct exposure to light, and the photodegradation rate is reduced; at the same time, after the active ingredients are dispersed to the nanometer level, the particle size is extremely small, and the degree of dispersion is extremely high. The compatibility, contact time and contact area are all greatly increased, and the nanoparticles have a tunnel effect, which can easily pass through the gaps between the pest cells, the...
