Problems solved by technology

[0002] Pesticides are mainly used to prevent and control agricultural pests and urban sanitation pests. They have a long history of use, are used in large quantities, and have many varieties. There are a large number of compound insecticides on the market, but most of them are compounds between chemical pesticides. Most of these mixtures are highly toxic to humans and animals, which can easily cause human and animal poisoning, and after a long period of use, pests will also develop resistance, resulting in a reduction in the control effect

Abstract

The invention provides a nano composite pesticide as well as a preparation method and application thereof. The pesticide comprises the following components in parts by weight: 20-35 parts of a garlicextract, 15-20 parts of a hydrophilic high-molecular compound, 15-22 parts of a durian shell extract, 5-12 parts of thiamethoxam, 1-3 parts of abamectin, 5-8 parts of sodium dodecyl sulfate, 1-2 partsof tert-butylhydroquinone and 4-9 parts of polyoxyethylene. The preparation method comprises the following steps: preparing a garlic extract and a durian shell extract; mixing thiamethoxam, abamectin, sodium dodecyl sulfate, tert-butylhydroquinone, polyoxyethylene and a hydrophilic high-molecular compound, carrying out ball milling, adding the garlic extract and the durian shell extract, uniformly stirring, and carrying out spray drying to obtain the nano composite pesticide. The pesticide provided by the invention has the advantages of obvious insecticidal effect, simple components, wide sources and high environmental toxicity, and can replace a small amount of fertilizer.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a nanocomposite pesticide and its preparation method and application. Background technique [0002] Pesticides are mainly used to prevent and control agricultural pests and urban sanitation pests. They have a long history of use, are used in large quantities, and have many varieties. There are a large number of compound insecticides on the market, but most of them are compounds between chemical pesticides. Most of these mixtures are highly toxic to humans and animals, which can easily cause human and animal poisoning, and after a long period of use, pests will also develop resistance, resulting in a reduction in the control effect. [0003] With the rapid development of nanotechnology, nanomaterials are widely used in biotechnology, medicine, testing and other fields. Nanopesticides are not efficient and stable, have few chemical components, and have a certain slow-...
