Embodiment 1
[0106] Example 1 A 1% multifunctional environment-friendly emamectin benzoate aqueous solution
[0107] Raw material ratio:
[0108]
[0109]
[0110] Prepared by:
[0111] 1. Prepare various raw materials for the preparation of 1kg multifunctional water formulation according to the formula weight ratio;
[0112] II. Castor oil polyoxyethylene ether (EL-40), fatty alcohol polyoxyethylene ether (AEO-09), sodium dodecylsulfonate, tea saponin, fulvic acid, carboxymethyl chitosan Add glycerin into the stirred tank, inject 2 / 3 of deionized water, stir to dissolve, and obtain solution A;
[0113] III. Emamectin benzoate is added to the solution A, stirred, and dissolved to obtain solution B;
[0114] IV. Dissolve hydroxyethyl cellulose in the remaining deionized water, add this solution to solution B, then add 2,2`,4,4`-tetrahydroxybenzophenone, stir at room temperature to dissolve , add tributyl phosphate, stir evenly, stand still, and defoam. get the target product. ...
Embodiment 2

Abstract
The invention provides a multifunctional environment-friendly emamectin benzoate aqueous solution and a preparation method thereof. The aqueous solution comprises the following components by weight percent: 1%-7% of emamectin benzoate, 1%-10% of an agent A, 1%-5% of a functional agent, 1%-6% of an agent B and or 0.1%-10% of other pesticide auxiliaries. The multifunctional aqueous solution does not contain any organic solvents, is uniform and clear in appearance, and is stable after long-term standing. Field tests prove that the multifunctional environment-friendly emamectin benzoate aqueous solution has the fast-acting property comparable to that of market missible oil, and has the pesticide-effect persistence obviously superior to that of the market missible oil; in addition, the growth of plants applied to the aqueous solution can be obviously improved. Therefore, the multifunctional environment-friendly emamectin benzoate aqueous solution is remarkably superior to the missible oil and other water-based forms.
Description
technical field [0001] The invention belongs to the field of new formulations of pesticides, in particular to a new multifunctional and 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...
