Problems solved by technology

[0003] In existing fruit surface sprays, most pesticides, such as some rotenone-containing compounds, alkaloids, and synthetic organic chemical drugs, are harmful to the human body and are difficult to clean when eating fruits; When the spray pollutes the ground surface, the water produced by washing the fruit will further pollute the groundwater source. These toxic substances will eventually enter the human body, and the long-term pesticide residue in the human body will cause many diseases.
In addition, the existing spray preparation method is complicated, the preparation cycle is long, and the cost of raw materials and preparation is also high.
In addition, due to the genetic mutation and generation-by-generation inheritance of pests, they slowly begin to develop resistance to some commercially available pesticides, resulting in poor efficacy and high re-infestation rates, so the existing sprays are not durable enough to protect fruits

preparation example Construction

[0048] The invention also provides a preparation method of the spray.

[0049] The preparation method of the spray is obtained by uniformly dispersing the solute in the solvent.

[0050] The invention also provides the application of the spray.

[0051] The application method of the spray: dilute the spray 10-300 times with water before use.

[0052] When actually spraying, the described anti-insect and anti-rot spray concentrate is diluted to different multiples according to actual conditions, such as weather conditions, fruit size and degree of maturity, etc.

[0053]The specific usage of the anti-insect and anti-rot spray of the present invention: the spraying time is preferably before the pest infestation, when the fruit tree blooms, and when the fruit just grows, it is best to spray once every 9 to 11 days, with this time interval , Spray three times in a row, and in case of heavy rain, it should be sprayed once after the rain in time. Before spraying fruit trees, try ...

Embodiment 1

[0056] Embodiment 1: A kind of preparation method of fruit anti-insect and anti-rot spray

[0057] First prepare nanoscale bismuth stannate: 3.50g SnCl 4 ·5H 2 O was dissolved in 100 mL deionized water to obtain a clear solution; 4.85 g Bi(NO 3 ) 3 ·5H 2 O was dissolved in 100mL deionized water, appeared turbid, and was homogenized by ultrasonication. Then, SnCl 4 The solution was added to the Bi(NO 3 ) 3 In the solution, add 8g of NaOH solution to make the NaOH concentration of the whole solution 1mol / L. After stirring at room temperature for 20min, the suspension is transferred to a 500mL polytetrafluoroethylene liner hydrothermal kettle and heated at 200°C for 16h, then naturally cooled to At room temperature, the obtained pale yellow precipitate was centrifuged, washed with deionized water and absolute ethanol, and then dried in a constant temperature drying oven at 60 °C for 12 h to obtain a nanoscale granular bismuth stannate sample.

[0058] The solute component...

Embodiment 2

[0059] Embodiment 2: A kind of preparation method of fruit anti-insect and anti-rot spray

[0060] Prepare nano-scale cobalt stannate: according to the preparation method of bismuth stannate in the above-mentioned embodiment 1: Bi(NO 3 ) 3 ·5H 2 O is replaced by Co(NO 3 ) 2 ·6H 2 O, bismuth stannate was replaced by cobalt stannate, the hydrothermal reaction temperature and time were changed to 190°C for 18 hours, and the remaining steps were exactly the same as in Example 1.

[0061] The solute component of the mixed spray consists of the following raw materials in parts by weight: 2.00g sodium carboxymethylcellulose, 4.00g cobalt stannate, 1.72g montmorillonite, 0.86g stannous pyrophosphate, 5.00g garlic powder. The above-mentioned solute components are fully dispersed in 1 L of propylene glycol to obtain a spray concentrate.

The spray is prepared from solute and solvent, wherein the solute comprises a gel raw material, a bimetallic oxide, montmorillonite, stannous pyrophosphate and garlic powder; the gel raw material is at least one of sodium carboxymethyl cellulose, gelatin, agar, sodium hyaluronate, carrageenan, xanthan gum and pullulan; and the bimetallic oxide is at least one of bismuth stannate, cobalt stannate, bismuth vanadate, bismuth molybdate and iron molybdate. The spray disclosed by the invention can realize dual functionalization of insect prevention and rotting prevention, and does not contain any component harmful to a human body.

Description

technical field [0001] The invention relates to a spray, a preparation method and application thereof, and belongs to the field of pesticides. Background technique [0002] With the improvement of people's living standards, the demand and quality requirements for fruits are getting higher and higher. The most basic thing is that there should be no pests and diseases and fruit rot. Therefore, it is necessary to spray pesticides and other sprays to prevent pests and rot during the growth of fruits. . [0003] In existing fruit surface sprays, most pesticides, such as some rotenone-containing compounds, alkaloids, and synthetic organic chemical drugs, are harmful to the human body and are difficult to clean when eating fruits; When the spray pollutes the surface, the water produced by washing the fruits will further pollute the groundwater source. These toxic substances will eventually enter the human body, and the long-term pesticide residues in the human body will cause many...
