High-efficient cyhalothrin microcapsule suspending agent and preparation method thereof

Abstract

The invention discloses a high-efficient cyhalothrin microcapsule suspending agent and a preparation method thereof; the suspending agent comprises the following components by weight: 1%-10% of high-efficient cyhalothrin, 3%-20% of a capsule core solvent, 5%-30% of a capsule wall material, 3%-10% of an emulsifier, 1%-5% of a dispersant, 0.1%-10% of a pH adjusting agent, and the balance of deionized water. The invention also discloses the preparation method of the high-efficient cyhalothrin microcapsule suspending agent. The product of the invention is low in cost, stable in performance, good in insecticidal effect, long in persistent period, low in toxicity, friendly to environment, and safe for people and livestock, and can meet the requirements of insect pollution-free control.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, in particular to a high-efficacy-cyhalothrin microcapsule suspension and a preparation method thereof. Background technique [0002] Chemical control is an important means of preventing and controlling agricultural and forestry diseases and insect pests. Chemical pesticides play a very important role in increasing agricultural production and income. However, the use of pesticides, while ensuring food safety production, also brings a series of environmental and Social Issues. Not only due to the chemical pesticide itself, but also to a large extent 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 channels is as high as 50% to 60%. This is not only a waste of economy, but also causes extensive environmental po...

Problems solved by technology

However, the duration of the currently used Kungfu permethrin to control pests is too short, causing farmers to frequently use pesticides and continuously increase the dosage of pesticides. Many areas have caused the emergence of drug resistance. Therefore, prolonging the duration of the pesticide has become an urgent problem to be solved.

In addition, the dosage form currently used for lambda-cyhalothrin is still mainly emulsifiable concentrate. Due to the use of a large amount of organic solvents, it not only consumes a large amount of petrochemical resources, but also causes great pressure on the environment.
