Problems solved by technology

Among the pesticide formulations, emulsifiable concentrate is first restricted by the domestic pesticide market, because a large amount of organic solvents are used in the production process, which is prone to accidents such as combustion, explosion, and poisoning during production, storage, and transportation, and has a great negative impact on the environment.

Abstract

The invention discloses a hexaflumuron suspended emulsion which is characterized by comprising the following components in percentage by weight: 2.5-10% of hexaflumuron, 20-30% of dispersant, 1-10% of suspending agent, 2-4% of anti-freeze agent, 8-12% of emulsifying agent, 5-15% of solvent and balance of water. The 2.5-10% hexaflumuron suspended emulsion has the advantages of low pesticide cost, high efficiency, low toxicity and low residue content, and can effectively prevent and control multiple lepidopterous pests on vegetables, cotton, paddy rice, fruit trees and the like.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a hexaflumuron suspoemulsion. Background technique [0002] Pesticides play an important role in the prevention and control of diseases, insects, and weeds for humans and in ensuring stable and high yields of crops. However, the unreasonable large-scale abuse of pesticides over the years has caused human and animal poisoning, killing natural enemies and non-target organisms, especially the impact on farmland ecosystems and pollution of the natural environment has attracted the attention of pesticide management and scientific research workers. The National Development and Reform Commission pointed out that gradually replacing the existing traditional dosage forms with environmentally friendly new agents is the current development trend of pesticide preparations. Among the pesticide formulations, emulsifiable concentrates are first restricted by the domestic pesticide market, because a l...
