Embodiment 1

[0064] A preparation method of emamectin benzoate aqueous solution, comprising the following steps:

[0065] Add 1% glucose to 98.2% water, heat in a water bath at 50°C and stir until it is completely dissolved into a colorless clear liquid; add 0.8% emamectin benzoate original drug, and control the temperature in a water bath at 50°C Heating and stirring until the whole solution is dissolved into a yellow clear liquid, thus obtaining 0.5% emamectin benzoate aqueous solution.

Embodiment 2

[0067] A preparation method of emamectin benzoate aqueous solution, comprising the following steps:

[0068] Add 2% gluconic acid into 96.5% water, heat and stir in a water bath at 65°C until it is completely dissolved into a colorless clear liquid; ℃ heating and stirring until all dissolved into a yellow clear liquid to obtain "1% emamectin benzoate aqueous solution".

Embodiment 3

[0070] A preparation method of emamectin benzoate aqueous solution, comprising the following steps:

[0071] Add 3% of gluconolactone into 93.4% of water, heat and stir in a water bath at 60°C until it is completely dissolved into a colorless clear liquid; Heat at 60°C and stir until all of it dissolves into a yellow clear liquid to obtain "2.5% emamectin benzoate aqueous solution".

Abstract

The preparation method comprises the following steps: adding 1%-5% of a glucose cosolvent into 80%-98.2% of water, controlling the temperature in a water bath at 50-80 DEG C, heating, and stirring until the glucose cosolvent is completely dissolved; then adding 0.8-15% of emamectin benzoate active compound, controlling the temperature in a water bath to be 50-80 DEG C, heating, and stirring until the emamectin benzoate active compound is completely dissolved; the water-soluble pesticide composition has the characteristics of no organic solvent or surfactant, stable quality, good water solubility, capability of being compounded with various water-soluble pesticides, simple production process and low production cost. And due to the addition of the glucose cosolvent, the adhesion and trapping and killing properties of the preparation are improved, and the effective utilization rate is further improved.

Description

technical field [0001] The invention belongs to the technical field of pesticide emamectin emamectin salt solution, in particular to a kind of emamectin benzoate aqueous solution and a preparation method thereof. Background technique [0002] Emamectin benzoate, (abbreviated as Emamectin benzoate, EB), the structural formula is as follows figure 2 As shown, it is a super-efficient insecticide and acaricide obtained by chemical modification starting from the biological antibiotic pesticide avermectin B1a. It has the characteristics of ultra-high efficiency, broad spectrum, low toxicity, no residue, and low drug resistance. [0003] [0004] Drug efficacy tests show that emamectin benzoate has incomparable activity against many pests, especially against Lepidoptera and Diptera. Tobacco Manduca, Diamondback Armyworm, Beet Spodoptera, Dry Land Armyworm, Spodoptera, Cabbage Spodoptera, Cabbage Pieris, Cabbage Heart Borer, Cabbage Barrel Borer, Tomato Manhawk, Potato Beetle, ...
