Problems solved by technology

However, the existing EC insecticides have poor stability and emulsifying properties, and the adhesion on the plant surface is insufficient when spraying. Therefore, the pesticides are not resistant to rainwater washing, and the persistence is relatively short, which is the most important. What is more important is that the existing EC insecticides use methanol as a solvent, which is highly toxic when sprayed and has a low flash point, thus bringing great harm to the environment and human health, which will endanger the country's economic development and human survival. surroundings

Abstract

The invention discloses a preparation method of a missible oil type insecticide, and relates to the technical field of farm chemical production. The missible oil type insecticide comprises the following components by weight: 4.5-6.5% of beta-cypermethrin, 8.6-10.4% of a 2201 emulsifier, 0.4-0.8% of a synergist, 0.02-0.06% of an antifoaming agent, and 0.04-0.08% of an adhesive, with the balance being solvent xylene. The missible oil type insecticide disclosed by the invention is prepared by taking the beta-cypermethrin, the 2201 emulsifier, the synergist, the defoaming agent, the adhesive and the balance of solvent xylene as raw materials, and is excellent in emulsifying property and plant surface adhesive force and relatively long in lasting effect, so that the insecticidal effect is good; in addition, methanol is not used in the formula, although the production cost of the insecticide is improved to a certain extent, the prepared insecticide is relatively low in toxicity, relatively high in flash point, less in environmental pollution and relatively good in safety.

Description

technical field [0001] The invention relates to the technical field of pesticide production, more specifically, it relates to a preparation method of an emulsifiable cream type insecticide. Background technique [0002] For a long time, the structure of pesticide products in my country has been seriously irrational, and the impact on human life and the ecological environment has become increasingly prominent. On January 1, 2007, my country completely banned the production and application of five highly toxic pesticides, methamidophos, methyl parathion, parathion, monocrotophos, and ammonium phosphate. In 2010, my country completely stopped the new registration and production license of 22 highly toxic pesticides such as isocarbophos and carbofuran. In June 2011, it stopped accepting new field test applications, registration applications and production license applications for 22 kinds of pesticides such as difenthion, fenamiphos and methylthion. [0003] In the use of pest...
