Embodiment 1
[0105] Example 1 A 1% multi-functional environment-friendly thiamethoxam aqueous solution
[0106] Raw material ratio:
[0107]
[0108] Prepared by:
[0109] I. prepare various raw materials for preparing 1kg target product according to formula weight ratio;
[0110] II. Castor oil polyoxyethylene ether (EL-40), fatty alcohol polyoxyethylene ether (AEO-09), sodium dodecylsulfonate, sodium laurate, tea saponin, fulvic acid, carboxymethyl Add chitosan and glycerin into the stirred tank, inject 2 / 3 of deionized water, stir at room temperature to dissolve, and obtain solution A;
[0111] III. Add thiamethoxam to the solution A, stir, and dissolve to obtain solution B;
[0112] IV. Dissolve hydroxyethyl cellulose in the remaining deionized water, add this solution to solution B, stir at room temperature to dissolve; then add tributyl phosphate, stir slightly, stand still, and filter to obtain brown-red , The target product with a transparent appearance.

Abstract
The invention provides a multifunctional environmental-friendly thiamethoxam aqua. The multifunctional environmental-friendly thiamethoxam aqua contains the following ingredients in percentage by weight: 1-5% of thiamethoxam, 1-10% of action agent A and 1-5% of functional agent, wherein the action agent A is one or more selected from sulfonic acid group containing anionic surfactant, sulfuric acid group containing anionic surfactant and carboxylic acid group containing anionic surfactant; preferably, the multifunctional environmental-friendly thiamethoxam aqua can also contain an action agent B which is 1-6% the total weight of the multifunctional environmental-friendly thiamethoxam aqua. The invention further also provides a method for preparing the multifunctional environmental-friendly thiamethoxam aqua. Proved by experiments, the indoor insecticidal activity of the multifunctional environmental-friendly thiamethoxam aqua provided by the invention is equivalent to that of a thiamethoxam aqueous dispersion with concentration which is the same as that of the multifunctional environmental-friendly thiamethoxam aqua. The thiamethoxam aqua provided by the invention does not contain any organic solvent, is of a uniform clarified solution in appearance and is stable in long-term placement, so that the thiamethoxam aqua is obviously better than emulsified oil preparations and other water-based preparation forms.
Description
technical field [0001] The invention belongs to the field of new formulations of pesticides, and in particular relates to a novel multifunctional environment-friendly thiamethoxam aqueous agent and a preparation method thereof. Background technique [0002] With the improvement of environmental protection awareness, the requirements for high efficiency and environmental friendliness of pesticide formulations are put forward. Studies have found that for the same pesticide technical, the effectiveness of the pesticide formulation depends on its formulation type and the dispersion state and size of the pesticide particles. Scientific common sense tells us that when other conditions are the same, the smaller the particle size of the pesticide original drug is, the larger its surface area is, and the wider the contact area with plant leaves and pests is, the more fully the drug effect will be, and the amount of pesticide used will be lower. reduce accordingly. [0003] Whether ...
