Embodiment 1

[0025] The present embodiment provides a pesticide suspension, comprising the following components by mass percentage: emamectin benzoate 2.0%, Bacillus thuringiensis 4000IU / mg, fast T 1.0%, sodium benzoate 0.4% , polycarboxylate 3.0%, phosphate ester 3.0%, nonylphenol polyoxyethylene ether 6.0%, xanthan gum 0.2%, propylene glycol 5.0%, silicone defoamer 0.4%, and the balance of deionized water was added.

[0026] The preparation method of this pesticide suspension concentrate specifically comprises the steps:

[0027] (1) Put emamectin benzoate, Bacillus thuringiensis, fast T, sodium benzoate, polycarboxylate, phosphate ester, nonylphenol polyoxyethylene ether, xanthan gum, and propylene glycol into deionized water , sheared in a high-speed shear for 1 h to obtain a mixture.

[0028] (2) Pump the above-mentioned mixed solution into a horizontal sand mill through a pneumatic diaphragm pump, start the sand mill, and pass two sand mills in series for sand milling for 3 hours, s...

Embodiment 2

[0030] The present embodiment provides a pesticide suspension, comprising the following components by mass percentage: emamectin benzoate 8.0%, Bacillus thuringiensis 6000IU / mg, azone 5.0%, sodium benzoate 0.8%, 8.0% of polycarboxylate, 2.0% of phosphoric acid ester, 2.0% of nonylphenol polyoxyethylene ether, 0.2% of xanthan gum, 8.0% of ethylene glycol, 0.5% of silicone defoamer, and the balance of deionized water is added.

[0031] The preparation method of this pesticide suspension concentrate is identical with embodiment 1.

Embodiment 3

[0033]The present embodiment provides a pesticide suspension, comprising the following components by mass percentage: emamectin benzoate 2.0%, Bacillus thuringiensis 12000IU / mg, azone 0.5%, sodium benzoate 0.3%, 2.0% of polycarboxylate, 8.0% of phosphoric acid ester, 4.0% of nonylphenol polyoxyethylene ether, 1.8% of xanthan gum, 2.0% of ethylene glycol, 0.1% of silicone defoamer, and the balance of deionized water was added.

[0034] The preparation method of this pesticide suspension concentrate is identical with embodiment 1.

Abstract

The invention provides a pesticide suspension agent. The pesticide suspension agent is prepared from the following components in percentage by mass: 1.0 to 10.0 percent of emamectin benzoate, 2,000 to12,000 IU / mg of bacillus thuringiensis, 0.5 to 10 percent of synergist, 4.4 to 43.5 percent of auxiliary agent and the balance of de-ionized water. According to the pesticide suspension agent provided by the invention, two reagents with different acting mechanisms, i.e., the emamectin benzoate and the bacillus thuringiensis, are blended and are used as main components of pesticide; the resistanceof insect pests on a single medicament is easy to delay, so that the pesticide effect of the pesticide is improved and the utilization period of the pesticide is prolonged; meanwhile, the synergist is matched to improve the permeability of the pesticide; the two main components are mutually blended and the synergetic effect is obvious; the application amount of the pesticide is reduced and the pesticide cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide suspension containing emamectin benzoate and Bacillus thuringiensis and a preparation method and application thereof. Background technique [0002] The rice leaf roller is one of the main pests in China's rice producing areas. It is widely distributed in various rice areas. It damages rice with larvae, sews leaves into longitudinal bracts, hides in it and feeds on the upper epidermis and mesophyll, leaving only the white lower epidermis; the seedling stage is damaged Affect the normal growth of rice, or even die; the tillering stage to the jointing stage is damaged, the tillering is reduced, the plant is shortened, and the growth period is delayed; the flag leaf is damaged after booting, especially from the heading to the full heading stage, which affects flowering and fruiting, increases the empty shell rate, and decreases the thousand-grain weight. ...
