Problems solved by technology

[0002] In the process of actual use of pesticide preparation products, after the pesticide preparation is diluted in the tank with water taken on site, the pH of the water source is different due to the different water source environments in different places, such as acidic, alkaline, hard water, and more suspended particles in the water. In the process of tank mixing, precipitation and flocculation of the medicinal solution occur (resulting in that the diluted medicinal solution cannot form a stable and uniform continuous phase, and the concentration of the medicinal solution on the target is different, which is prone to phytotoxicity in some plots, serious Reduce the effective activity of pesticides), during the spraying process, due to the high surface tension of the liquid medicine, the liquid medicine is ejected on the target or the surface tension of the liquid medicine is too low, resulting in runoff of the liquid medicine on the target
Various factors lead to reduced efficacy and unsatisfactory control effects, which may lead to users blindly increasing the effective content of pesticides, resulting in economic losses

Embodiment 1

[0026] The present embodiment provides a suspending agent, comprising the following components by mass percentage: 2.0% lecithin, 35% vitamin B, 1.0% sodium dioctyl sulfosuccinate, 0.4% sodium benzoate, polycarboxylate 3.0%, phosphoric acid ester 3.0%, nonylphenol polyoxyethylene ether 6.0%, xanthan gum 0.2%, propylene glycol 5.0%, silicone defoamer 0.4%, and deionized water to add the balance.

[0027] The preparation method of this suspending agent specifically comprises the steps:

[0028] (1) Lecithin, vitamins, dioctyl sulfosuccinate sodium salt, sodium benzoate, polycarboxylate, phosphoric acid ester, nonylphenol polyoxyethylene ether, xanthan gum, propylene glycol are dropped into deionized water, in Cut for 1.5 h in a high-speed shearing machine to obtain a mixed solution.

[0029] (2) The above-mentioned mixed solution is pumped into a horizontal sand mill by a pneumatic diaphragm pump, the sand mill is started, and three sand mills are connected in series for 4.5 ho...

Embodiment 2

[0031] The present embodiment provides a suspending agent, comprising the following components by mass percentage: 8.0% lecithin, 10.0% vitamin E, 5.0% azone, 0.8% sodium benzoate, 8.0% polycarboxylate, phosphoric acid ester 2.0%, 2.0% nonylphenol polyoxyethylene ether, 0.2% xanthan gum, 8.0% ethylene glycol, 0.5% organic silicon defoamer, and add the balance of deionized water.

[0032] The preparation method of this suspending agent is identical with embodiment 1.

Embodiment 3

[0034] The present embodiment provides a suspending agent, comprising the following components by mass percentage: 2.0% lecithin, 10.0% vitamin E, 0.5% azone, 0.3% sodium benzoate, 2.0% polycarboxylate, phosphoric acid ester 8.0%, 4.0% nonylphenol polyoxyethylene ether, 1.8% xanthan gum, 2.0% ethylene glycol, 0.1% organic silicon defoamer, and add the balance of deionized water.

Abstract

The invention discloses a pesticide suspension synergist containing lecithin and vitamins. The pesticide suspension synergist comprises the following components: lecithin, vitamins, a preservative, a dispersing agent, a wetting agent, a thickening agent, an anti-freezing agent, a defoaming agent and deionized water, the preparation method of the pesticide suspension synergist containing lecithin and vitamin comprises the following steps: 1) drying the raw materials, and crushing; 2) putting the crushed raw materials into deionized water, and shearing in a high-speed shearing machine for 1.5 hours to obtain a homogeneous mixed solution; 3) pumping the mixed solution into a sand mill for sand milling, so that the particle size of particles in the mixed solution is 3-5 [mu] m; and (4) pumping the liquid obtained in the step (3) into a shearing kettle and a homogenizing kettle, and homogenizing to obtain the suspension. Compared with the prior art, the invention has the advantages that: the pesticide liquid is prevented from precipitating and flocculating, the surface tension of the pesticide liquid is stabilized to reach the maximum value of the retention volume of the target pesticide liquid, the metabolic capability of crops on selective herbicides is improved, and the phytotoxicity is reduced.
