Description

Technical Field

[0001] The present application relates to the technical field of pesticides, and in particular to a pesticide composition containing glufosinate ammonium, a preparation method and an application thereof. Background Art

[0002] As a broad-spectrum and highly effective herbicide active ingredient, glufosinate is widely used in agricultural production. However, traditional glufosinate preparations have problems such as poor stability, easy decomposition, and large usage, which not only increase the cost of use for farmers, but also cause certain pollution to the environment. Therefore, how to improve the stability and efficacy of glufosinate, reduce usage and environmental pollution, has become a problem to be solved in the current field of pesticide technology. In addition, some agricultural products such as glufosinate and refined glufosinate on the market will have flatulence problems during long-term storage, resulting in damage and leakage of product packaging, increasing the potential safety hazards of logistics and warehousing, and also affecting the performance and shelf life of the product. Summary of the invention

[0003] In order to solve at least one of the above technical problems, a pesticide with a long lasting effect, good efficacy and the ability to prevent flatulence is developed. The present application provides a pesticide composition containing glufosinate ammonium, a preparation method and an application.

[0004] In a first aspect, the present application provides a pesticide composition containing glufosinate ammonium, wherein the pesticide composition containing glufosinate ammonium comprises a core body and an inclusion body coating the core body;

[0005] The core comprises potassium sorbate, cinnamon oil and glufosinate ammonium;

[0006] The inclusions include dopamine hydrochloride, diatomaceous earth and tris(hydroxymethyl)aminomethane.

[0007] The weight ratio of the core body to the inclusion body is (2-3):1.

[0008] By adopting the above technical scheme, the pesticide composition containing glufosinate ammonium proposed in this application solves the technical problems of poor stability, easy decomposition, large usage and flatulence in traditional pesticide preparations through its unique double-layer structure design, that is, the core composed of potassium sorbate, cinnamon oil and glufosinate ammonium, and the inclusions composed of dopamine hydrochloride, diatomaceous earth and tris (hydroxymethyl) aminomethane. The core of this technical solution lies in the precise coating of the core by the inclusion, which not only significantly enhances the stability of the pesticide, but also effectively prevents the flatulence caused by the volatilization of the components. Specifically, the dopamine hydrochloride in the inclusion is polymerized in situ to form a tight protective layer. This layer of film can effectively isolate the core from the external environment, reduce the direct contact of glufosinate and other components with the air, thereby preventing their decomposition and volatilization, which is the key to achieving the anti-flatulence effect. At the same time, diatomaceous earth, as an excellent carrier material, has good adsorption and pore structure, can adsorb and stabilize the effective ingredients in the core, and slow down its release rate. Tris(hydroxymethyl)aminomethane plays a role in pH regulation and can provide a suitable pH environment for dopamine hydrochloride to polymerize in situ. In addition, the weight ratio of the core to the inclusion body (2-3): 1 is set so that the entire pesticide composition can achieve the optimal match between the components while maintaining high efficacy, further enhancing the stability of the product, reducing the potential toxicity to non-targeted plants, and achieving the dual goals of environmental protection and high efficiency. In the present application, when selecting the core raw material, potassium sorbate, cinnamon oil and glufosinate ammonium are used as the core raw materials, which can better avoid the occurrence of flatulence. Among them, potassium sorbate, as a preservative, can effectively inhibit the growth of microorganisms and avoid the decomposition and flatulence of glufosinate ammonium caused by microbial activity during storage, thereby ensuring the stability and long-term storage performance of the pesticide composition. In addition to its natural antibacterial and antifungal properties, cinnamon oil can also be used as a biostimulant to enhance the biological activity of glufosinate ammonium and improve its control effect on weeds. At the same time, the addition of its volatile components can also inhibit the growth of harmful microorganisms, further reducing the risk of flatulence. As the core herbicidal active ingredient, glufosinate-ammonium has a high-efficiency and broad-spectrum herbicidal effect. Under the synergistic protection of potassium sorbate and cinnamon oil, the stability of glufosinate-ammonium is enhanced, reducing its decomposition rate during storage, thereby avoiding the flatulence caused by the accumulation of decomposition products. The double-layer structure design of the nucleus and the inclusion body, through the effective coating of the inclusion body to the nucleus, not only forms a physical barrier, prevents the influence of the external environment on the nucleus components, but also through the sustained release performance of dopamine hydrochloride in the inclusion body, the adsorption capacity of diatomaceous earth and the pH regulating effect of TRIS, jointly maintains the stability of the pesticide composition, reduces the volatilization of the active ingredient, thereby effectively preventing the occurrence of flatulence. In addition, the pesticide composition provided by the present application adopts a diversified active ingredient design, in addition to glufosinate-ammonium, potassium sorbate and cinnamon oil are also included.Each of these ingredients has a unique biological activity and can attack weeds through different mechanisms of action, thereby reducing the risk of weeds developing resistance to a single ingredient. In particular, the addition of potassium sorbate and cinnamon oil not only enhances the control effect on weeds, but also broadens the spectrum of action, showing a significant inhibitory effect on a variety of resistant weeds. By encapsulating active ingredients such as glufosinate in a specific material, a controlled-release pesticide composition is formed. This design can achieve the sustained release of active ingredients, prolong the efficacy time, and reduce the number of times of application, thereby avoiding the risk of accelerating the development of weed resistance due to frequent and large-scale use of a single glufosinate. The application of controlled-release technology controls the amount of pesticide residues in the soil, reduces the potential harm to non-target organisms, achieves precise medication, and improves resource utilization efficiency. This application focuses on environmental friendliness, and through carefully selected formula ingredients, reduces the negative impact on the ecological environment. Potassium sorbate and cinnamon oil are both natural substances, which are safe for the human body and the environment, and are easy to degrade and will not cause long-term environmental pollution. In addition, by optimizing the ratio of each component, the use of glufosinate is reduced, the potential pollution to soil and water bodies is alleviated, and the sustainable development of agriculture is promoted.

[0009] In summary, the technical solution of the present application not only greatly improves the stability of the pesticide and prevents flatulence by effectively coating the core with inclusions, but also realizes the precise controlled release of ingredients, providing an innovative, efficient and environmentally friendly solution for the pesticide field. At the same time, the pesticide composition of the present application effectively solves the problem of resistant weed control through diversified active ingredients, controlled release technology, environmentally friendly formula design and efficient synergy, avoids the problems caused by excessive use of a single glufosinate ammonium, and provides a more green, efficient and sustainable pest management strategy for modern agriculture.

[0011] Optionally, the core comprises potassium sorbate, cinnamon oil and glufosinate ammonium in a weight ratio of (3-5):(3-5):(55-60).

[0012] By adopting the above technical scheme, the ratio of potassium sorbate and cinnamon oil not only strengthens the antiseptic and antibacterial properties of the pesticide composition, but also effectively prevents the decomposition and flatulence caused by microbial activity, and significantly improves the long-term storage stability of the product. At the same time, this adjustment also enhances the biological activity and weeding effect of glufosinate ammonium, reduces the overall dosage, reduces potential pollution to the environment, and especially reduces the toxic effects on non-targeted plants. By optimizing the weight ratio between each component, the pesticide composition of the present application not only maintains efficient efficacy, but also significantly enhances its stability, reduces the risk of flatulence, achieves the dual goals of environmental protection and high efficiency, and provides an innovative, efficient and environmentally friendly weeding solution for the agricultural field.

[0017] By adopting the above technical scheme, the addition of auxiliary agents, particularly wetting agents and surfactants, significantly improves the spreadability and adhesion of the pesticide composition on the target crop surface, improves the absorption efficiency of effective ingredients such as glufosinate ammonium, thereby enhancing the weeding effect. The use of dispersants and thickeners ensures that the pesticide composition is evenly dispersed during spraying, avoids deposition and drift, and improves the efficiency of use. And the application of synergists not only further enhances the efficacy, but also promotes the interaction between glufosinate ammonium and weed cell walls, and accelerates the weeding process. Through the reasonable proportion of the above-mentioned auxiliary agents, the pesticide composition of the present application, while ensuring efficient weeding effect, significantly improves its application performance, reduces the usage amount, reduces the potential toxicity to non-targeted plants, and achieves environmental friendliness.

[0024] By adopting the above technical scheme, the present application provides an innovative preparation method of a pesticide composition containing glufosinate, which cleverly combines the process steps of chemical dissolution, uniform mixing, ultrasonic dispersion and drying, and aims to comprehensively optimize the performance of the pesticide composition, ensuring that it is efficient, stable and environmentally friendly. Specifically, the pre-dissolution of cinnamon oil in anhydrous ethanol not only improves its dispersibility in the subsequent mixing process, but also enhances its biological activity, ensuring the efficient weeding effect of the pesticide composition. The preliminary mixing of potassium sorbate and glufosinate with water, supplemented by the addition of an auxiliary agent, ensures that the components are fully contacted and evenly distributed, and the mixing of cinnamon oil solution again further enhances the interaction between the components and improves the overall effectiveness of the pesticide composition. Subsequently, the addition of diatomaceous earth and long-term mixing not only provide good carrier support, but also promote the stable encapsulation of active ingredients through its unique pore structure, and enhance the controlled release performance and stability of the pesticide composition.

[0062] Example 3

[0063] The difference between this embodiment and embodiment 1 is that the total weight of potassium sorbate, cinnamon oil and glufosinate ammonium is 540 g, wherein the weight ratio of potassium sorbate, cinnamon oil and glufosinate ammonium is 4:4:58 (this weight ratio is based on 540 g).

[0064] Example 4

[0065] The difference between this embodiment and embodiment 1 is that the total weight of potassium sorbate, cinnamon oil and glufosinate ammonium is 540 g, wherein the weight ratio of potassium sorbate, cinnamon oil and glufosinate ammonium is 5:5:60 (this weight ratio is based on 540 g).

[0066] Comparative Example 1

[0067] The difference between this comparative example and Example 3 is that no inclusion body is included when preparing a pesticide composition containing glufosinate ammonium.

[0068] Comparative Example 2

[0069] The difference between this comparative example and Example 3 is that when preparing a pesticide composition containing glufosinate ammonium, an equal amount of potassium sorbate is used to replace cinnamon oil.

[0070] Comparative Example 3

[0071] The difference between this comparative example and Example 3 is that when preparing a pesticide composition containing glufosinate ammonium, an equal amount of cinnamon oil is used to replace potassium sorbate.

[0072] Comparative Example 4

[0073] The difference between this comparative example and Example 3 is that when preparing a pesticide composition containing glufosinate ammonium, the core body is entirely glufosinate ammonium.

[0074] Experimental testing:

[0075] Efficiency of control of Setaria: Apply pesticides to Setaria in the experimental farmland, and record the weed control rate after 5 days and 10 days (set up a group of control experiments, in which no pesticides were sprayed).

[0076] Ryegrass control efficiency: Apply pesticides to ryegrass in the experimental farmland, and record the control efficiency after 5 days and 10 days (set up a group of control experiments, in which no drugs were sprayed).

[0077] Control efficiency: (number of surviving weeds in the control area - number of surviving weeds in the treatment area) / number of surviving weeds in the control area * 100%.

[0078] Bloating phenomenon: The glufosinate-ammonium-containing pesticide compositions prepared in Examples 1-4 and Comparative Examples 1-4 were vacuum-packed, placed for 3 months, and observed whether there was any bloating phenomenon within 3 months (temperature was 35° C.).

[0079] The experimental test results of Examples 1-4 and Comparative Examples 1-4 are shown in Table 1.

[0080] Table 1 - Experimental test results of Examples 1-4 and Comparative Examples 1-4

[0081]

[0082] Result analysis: The difference between Examples 2-4 and Example 1 is that when preparing a pesticide composition containing glufosinate, the weight ratio of potassium sorbate and glufosinate constituting the core body is different. Combined with the experimental test data of Table 1, it can be seen that the potassium sorbate glufosinate prepared by Example 3 has a lower impact on the environment and non-target organisms. The difference between Comparative Example 1 and Example 3 is that when preparing a pesticide composition containing glufosinate, no inclusion is included. Combined with the test results provided in Table 1, it can be seen that when preparing a pesticide composition containing glufosinate, when the inclusion is not used to encapsulate the active ingredient, although there is a good removal rate for weeds in the initial stage of application, as time goes by, the weeds will turn green. Combined with the experimental test results of Example 3 and Comparative Example 1, it can be seen that when the technical solution of the present application is used to encapsulate the active ingredient of the pesticide, the active ingredient of the pesticide can be controlled and released, thereby playing a long-term removal and prevention role on weeds. The difference between Comparative Example 2 and Example 3 is that when preparing a pesticide composition containing glufosinate, an equal amount of potassium sorbate is used to replace cinnamon oil. Combined with the experimental test results of Table 1, it can be seen that when preparing a pesticide composition containing glufosinate, an equal amount of potassium sorbate is used to replace cinnamon oil, and flatulence will occur during storage. The difference between Comparative Example 3 and Example 3 is that when preparing a pesticide composition containing glufosinate, an equal amount of cinnamon oil is used to replace potassium sorbate. Combined with the experimental test results of Table 1, it can be seen that when preparing a pesticide composition containing glufosinate, an equal amount of cinnamon oil is used to replace potassium sorbate. Although the efficacy of the prepared pesticide composition can be improved to a certain extent, flatulence will still occur during storage. The difference between Comparative Example 4 and Example 3 is that when preparing a pesticide composition containing glufosinate, the core body is all glufosinate. Combined with the experimental test results in Table 1, it can be seen that when preparing a pesticide composition containing glufosinate ammonium, if cinnamon oil and potassium sorbate are not added, glufosinate ammonium will decompose during storage, resulting in flatulence.
