Problems solved by technology

[0007] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, provide a kind of pesticide diluent and preparation method thereof, to overcome the existing use of water dilution easily lead to pesticide precipitation, flocculation, crystallization, volatile, drift so that the diluent during operation Poor stability, prone to stratification, resulting in nozzle blockage, phytotoxicity, and the use of traditional low-capacity and ultra-low-capacity thinners with high toxicity, strong odor, easy to damage crops, and pollute the environment.
[0008] Another object of the present invention is to provide the application of the pesticide diluent of the present invention to solve the technical problems such as the existing pesticide diluent has high toxicity, pollutes the environment and easily makes the diluted pesticide solution system unstable.

preparation example Construction

[0033] Correspondingly, on the basis of the above-mentioned pesticide diluent example, the embodiment of the present invention also provides a preparation method of the above-mentioned pesticide diluent. This pesticide diluent preparation method comprises the steps:

[0034] Step S01: weighing each component according to the following component ratios: 40%-90% hydrophilic solvent, 1%-10% surfactant, 1%-10% humectant and 0-50% water;

[0035] Step S02: Mixing the components weighed in step S01.

[0036] Specifically, the preferred types and contents of the hydrophilic solvent, surfactant, and humectant in the above-mentioned step S01 are all as the preferred hydrophilic solvent, surfactant, and humectant described in the pesticide diluent embodiment above. The types and contents are not repeated here in order to save space.

[0037] The mixing treatment of the components taken symmetrically in the above step S02 can be, but not limited to, such as stirring treatment, homogeni...

Embodiment 1

[0044] A pesticide diluent and a preparation method thereof. The pesticide diluent consists of the following components:

[0045] Glycerin formal 90%, fatty alcohol polyoxyethylene ether AEO-95%, propylene glycol 5%.

[0046] The preparation method of the pesticide diluent: according to the formula of the pesticide diluent in this example, weigh glycerin formal, fatty alcohol polyoxyethylene ether AEO-9 and propylene glycol respectively, and then weigh glycerin formal, fatty alcohol polyoxyethylene ether AEO-9 Mix with propylene glycol by means of stirring or homogenizer until a homogeneous and transparent mixed solution is formed.

[0047] Performance Testing:

[0048] Several emulsifiable concentrate products purchased in the market as shown in Table 1 were diluted with the pesticide diluent provided in Example 1 to form a dilution. At the same time, the commonly used diesel oil, second-line oil, and solvent oil diluents were used as comparative examples to dilute these s...

Embodiment 2

[0054] A pesticide diluent and a preparation method thereof. The pesticide diluent consists of the following components:

[0055] Glycerin formal 70%, fatty alcohol polyoxyethylene ether AEO-92%, polyoxyethylene sorbitan fatty acid ester (Tween) 3%, alkyl glycoside 5%, propylene glycol 5%, water 15%.

[0056] Its preparation method refers to the preparation method of the pesticide diluent in Example 1.

[0057] Performance Testing:

[0058] The pesticide diluent provided in Example 2 was used to dilute several suspension concentrate products purchased in the market as shown in Table 2 to form a dilution. At the same time, the common water+urea and water+salt diluents were used as the comparison ratio to dilute these several emulsions, and the relevant performance tests in Table 2 were carried out for each dilution, and the test results were shown in Table 2.

[0059] It can be seen from Table 2 that after the pesticide diluent provided in Example 2 dilutes the suspension, t...

Abstract

The present invention discloses a pesticide diluent and a preparation method and applications thereof. The pesticide diluent provided by the invention comprises in percentage by mass: 40%-90% of a hydrophilic solvent, 1%-10% of a surfactant, 1%-10% of a humectant and 0-50% of water . The pesticide diluent preparation method provided by the invention comprises the steps of: weighing components according to component proportions of 40%-90% of a hydrophilic solvent, 1%-10% of a surfactant, 1%-10% of a humectant and 0-50% of water; and mixing the weighed components. The pesticide diluent provided by the invention is used for diluting pesticides and / or foliar fertilizers. The pesticide diluent provided by the invention has the advantages of being moisturizing, anti-volatilizing, anti-drifting, quick in droplet precipitation, uniform in granularity, stable, low in toxicity for people and livestock, environmentally friendly, high in flash point, safe in usage and so on. According to the pesticide diluent preparation method, the pesticide diluent performance is stable and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide diluent and its preparation method and application. Background technique [0002] With the transformation and upgrading of agriculture and the continuous improvement of agricultural production technology, new agricultural planting models have emerged in the transfer of rural land. In the new era, the cost of agricultural labor continues to increase, forcing the widespread use of high-efficiency plant protection technologies. With the improvement of people's awareness of safety and environmental protection, in order to ensure food safety, reduce use costs, and reduce environmental pollution, it is necessary to further improve the spray quality of pesticides, improve efficacy, and reduce the amount of chemicals used. In order to achieve this purpose, modern low-capacity, ultra-low Spray technology such as capacity has been vigorously developed, especially the applic...
