Efficient cyfluthrin microcapsule suspending agent and preparation method thereof

Abstract

The invention relates to a preparation method of an efficient cyfluthrin microcapsule suspending agent. The microcapsule suspending agent is prepared by utilizing efficient cyfluthrin as a capsule core through a piercing-solidifying bath method. The microcapsule suspending agent comprises the following components in percentage by weight: 1%-40% of efficient cyfluthrin, 3%-15% of a capsule core solvent, 5%-10% of a capsule wall material, 3%-10% of an emulsifying agent, 1%-5% of a dispersing agent and the balance of water. The efficient cyfluthrin microcapsule suspending agent is high in stability, long in lasting period, safe in use and less in environmental pollution.

Description

technical field

[0001] The invention belongs to the field of pesticide preparations, in particular to a high-efficiency cyfluthrin microcapsule suspension and a preparation method thereof Background technique

[0002] Chemical control is an important means for human beings to prevent and control agricultural and forestry diseases and insect pests. Chemical pesticides play a very important role in ensuring the increase of agricultural production and income. However, the use of pesticides not only ensures the safe production of food, but also brings a series of environmental residues, pollution and so on. and social issues. It is only due to the chemical pesticide itself, and largely due to the unreasonable processing and application methods of pesticide formulations. According to reports, the utilization rate of conventional pesticides is only 20% to 30%, and the loss rate through various ways is as high as 50% to 60%, which is not only a waste of economy, but also causes a ...
