Embodiment 1

[0038] A kind of method that takes beeswax as substrate to prepare controlled release pesticide, comprises the steps:

[0039] (1) Adsorb 20% thiamethoxam in 10% kaolin to obtain mixture 1;

[0040] (2) Heat and melt 43% beeswax at 115° C., then add 2% Tween 80, and stir evenly; add 2% calcium carbonate, stir to make it evenly mixed, and obtain mixture 2;

[0041] (3) Add 25.5% of the mixture 1 obtained in step (1) to the mixture 2 obtained in step (2), and continue stirring for 35 minutes to obtain mixture 3;

[0042] (4) Continue to stir the mixture 3 obtained in step (3), add 10% kaolin and 13% white clay during the stirring process, and let it slowly cool down and solidify after stirring evenly to obtain mixture 4;

[0043] (5) After the mixture 4 obtained in step (4) is solidified and cooled to room temperature, it is dried, pulverized, and sieved to obtain a controlled-release pesticide with beeswax as the matrix.

Embodiment 2

[0059] A kind of method that takes beeswax as substrate to prepare controlled release pesticide, comprises the steps:

[0060] (1) Adsorb 20% thiamethoxam in 10% kaolin to obtain mixture 1;

[0061] (2) heating and melting 43% beeswax at 110° C., then adding 2% Tween 80, and stirring evenly; adding 4% calcium carbonate, stirring to make it evenly mixed, and obtaining mixture 2;

[0062] (3) Add 20% by weight of the mixture 1 obtained in the step (1) to the mixture 2 obtained in the step (2), and continue stirring for 25 minutes to obtain the mixture 3;

[0063] (4) Continue to stir the mixture 3 obtained in step (3), add 10% kaolin and 11% white clay during the stirring process, and let it slowly cool down and solidify after stirring evenly to obtain mixture 4;

[0064] (5) After the mixture 4 obtained in step (4) is solidified and cooled to room temperature, it is dried, pulverized, and sieved to obtain a controlled-release pesticide with beeswax as the matrix.

Embodiment 3

[0066] A kind of method that takes beeswax as substrate to prepare controlled release pesticide, comprises the steps:

[0067] (1) Adsorb 20% thiamethoxam in 10% kaolin to obtain mixture 1;

[0068] (2) Heat and melt 43% beeswax at 120°C, then add 2% Tween 80, and stir evenly; add 6% calcium carbonate, stir to make it evenly mixed, and obtain mixture 2;

[0069] (3) Add 30% by weight of the mixture 1 obtained in the step (1) to the mixture 2 obtained in the step (2), and continue stirring for 45 minutes to obtain the mixture 3;

[0070] (4) Continue to stir the mixture 3 obtained in step (3), add 10% kaolin and 9% white clay during the stirring process, and let it slowly cool down and solidify after stirring evenly to obtain mixture 4;

[0071] (5) After the mixture 4 obtained in step (4) is solidified and cooled to room temperature, it is dried, pulverized, and sieved to obtain a controlled-release pesticide with beeswax as the matrix.

Abstract

The invention discloses application of beewax in a controlled release pesticide and a method for preparing the controlled release pesticide by taking the beewax as a matrix and belongs to the technical field of controlled release pesticides. The controlled release pesticide taking the beewax as the matrix is prepared by utilizing pesticide active molecules, an adsorbent, beewax or modified beewax,a surfactant, a controlled release regulator and a filler. According to pesticide granules prepared by the method, the pesticide active molecules in the pesticide granules can be released in a certain period of time according to crop needs, the uncontrollability of release time of the conventional controlled release pesticide is solved, and an excellent effect of controlling crop pests is achieved. Moreover, the preparation process is simple, the raw materials are cheap, and the preparation cost is low.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to the application of beeswax in controlled-release pesticides, a method for preparing controlled-release pesticides using beeswax as a substrate, and the application thereof. Background technique [0002] The use of pesticides in farmland is generally applied in the form of emulsifiable concentrates, emulsions in water, microemulsions, suspensions, and soluble powders. The commercial forms of pesticides currently on the market cannot produce the required biological response to the target at the precise time and dosage, and the amount of these products used during the application process often far exceeds the expected effect on the biological target to be controlled. During the application process, the effective utilization rate of pesticide active molecules is generally less than 20%, the loss rate is as high as 50% to 60%, and the pesticide active molecules that can really reac...
