Embodiment 1
[0099] Example 1 A 1% environmentally friendly emamectin benzoate aqueous solution
[0100] Raw material ratio:
[0101]
[0102] Prepared by:
[0103] 1. Prepare various raw materials for preparing 1000kg water formulation according to the formula weight ratio;
[0104] II. Add sodium dodecyl sulfonate, castor oil polyoxyethylene ether (EL-40), carboxymethyl starch and glycerin into the stirring tank, inject part of deionized water, stir and dissolve to obtain solution A ;
[0105] III. Emamectin benzoate is added to the solution A, stirred, and dissolved to obtain solution B;
[0106] IV. Add the remaining deionized water into the solution B, stir, then add tributyl phosphate defoamer, stir slightly, stand still, and filter to obtain the target product with a transparent appearance. For samples, see figure 2 .
Embodiment 2
[0107] Example 2 A 2% environmentally friendly emamectin benzoate aqueous solution
[0108] Raw material ratio:
[0109]
[0110]
[0111] Using the preparation method and steps similar to Example 1, 1000kg of the target product was obtained.
Embodiment 3
[0112] Example 3 A 3% environmentally friendly emamectin benzoate aqueous solution
[0113] Raw material ratio:
[0114]
[0115] Adopt the preparation method and steps similar to Example 1, obtain 1000kg target product, see sample figure 2 .

Abstract
The invention provides an environment-friendly emamectin benzoate aqueous solution and a preparation method thereof. The environment-friendly emamectin benzoate aqueous solution comprises the following ingredients by weight percent: 1-7% of emamectin benzoate, 1-10% of an agent A and 1-6% of an agent B. The aqueous solution does not contain any organic solvent, is uniform and clear in appearance, and is stable after long-term standing; the insecticide effect is good, and therefore, the environment-friendly emamectin benzoate aqueous solution is obviously superior to missible oil and other water-based forms.
Description
technical field [0001] The invention belongs to the field of new pesticide formulations, and in particular relates to a new environment-friendly emamectin benzoate aqueous solution and a preparation method thereof. Background technique [0002] With the improvement of environmental protection awareness, there are requirements for high efficiency and environmental friendliness of pesticide formulations. 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 a pesticide dosage form...
