Problems solved by technology
Its disadvantages are: easy drift loss, environmental pollution, low pesticide recovery rate, large dosage, poor sedimentation and adhesion, low content of active ingredients, high packaging, storage and transportation costs
The problem with the suspension is that some preparations cannot be stored for a long time and are easy to agglomerate
[0010] With the enhancement of people's awareness of environmental protection, it is still a challenge to improve the performance of pesticides and their environmental friendliness

Embodiment Construction
[0038]The components of the new controlled-release pesticide dosage form based on biocompatible soft materials include pymetrozine, amino acid-based ionic liquid surfactant, water, and n-butanol. The aqueous solution of the liquid surfactant constitutes the pesticide stock solution, and the pesticide stock solution is stirred and dispersed to obtain a novel controllable release pesticide formulation microemulsion of a biocompatible soft substance. The formulation has two types of zone II and zone III, and the weight percentage of each component is : Zone II, 1.5% to 7% of pymetrozine, 0.5% to 20% of amino acid-based ionic liquid surfactants, 72 to 95.5% of water, and 0.5% to 1% of n-butanol; Zone III, pymetrozine Ketones are 1.5% to 6.0%, amino acid-based ionic liquid surfactants are 47.0% to 68.0%, and water is 23.0% to 48.0%. Butanol is 1.5% to 1%.

The invention discloses a novel controllable release pesticide formulation based on biological compatible soft materials and a method for preparing the controllable release pesticide formulation. The novel controllable release pesticide formulation comprises pymetrozine, amino acid radical ionic liquid surface active agents, water and n-butyl alcohol, the pymetrozine and the n-butyl alcohol are mixed, a water solution of the amino acid radical ionic liquid surface active agents is added to form a pesticide stock solution, and the pesticide stock solution is stirred and dispersed to prepare novel controllable release pesticide formulation micro-emulsion based on biological compatible soft materials. According to the method for preparing the novel controllable release pesticide formulation based on biological compatible soft materials, selected materials are scientific and reasonable, the method is simple, novel pesticide controllable release materials are composed of soft materials, the novel controllable release pesticide formulation based on biological compatible soft materials is developed, a novel carrier is provided for pesticide controllable release, and the novel controllable release pesticide formulation is applicable to insect killing for vegetables, rice, cotton and fruit trees. The pesticide effect is improved apparently, the pesticide demand amount can be reduced by more than 30%, the cost is reduced, and costs for packaging, storage, transportation and the like are decreased. The novel controllable release pesticide can promote technical progress and product optimization and upgrade of pesticide industry, and great economical benefits are produced.
Description
technical field [0001] The invention relates to a preparation method of a novel controllable release pesticide dosage form, belonging to the technical field of pesticide processing. Background technique [0002] Pesticide dosage form refers to the processing of the original pesticide to make it a finished product that can be applied with appropriate equipment. This process of changing the original medicine into the use form is called pesticide processing or pesticide formulation. Most of the original drugs must be processed into preparations before they can be applied. Therefore, the study of pesticide formulations is very important. [0003] There are many classification methods of pesticide dosage forms, the simplest classification method is to classify according to the physical properties of the preparations, that is, solid dosage forms and liquid dosage forms. According to the release characteristics of active ingredients, they can be divided into free release type and c...
