Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of chemical bird repellents, and specifically relates to the use of a bird repellent in the production of amino acid metal complexes.
Background Art
[0002] The absorption, transport and metabolism of amino acids by plants, as well as the use of amino acids in fertilizers and plant stimulants, have already been reported both in and outside of China. Studies have already proven that plants can directly absorb amino acid molecules in soil, and the transport, distribution and metabolism after such absorption vary depending on the type of amino acid, and the resulting physiological effects also differ. Amino acids are easily decomposed by sunlight or by microorganisms in the natural world, leave no residual toxicity in soil or plants, and their decomposition products can also improve the quality and yield of agricultural crops as nutrient substances for the crops. The application of such fertilizers is safe for humans and animals and causes no pollution. Amino acid fertilizers have the effects of promoting plant growth and development, enhancing tolerance, improving soil conditions, and increasing crop yield.
[0003] In the research on using amino acids as plant stimulants to promote the germination and growth of crop seeds, the resistance to external biological and abiotic stresses, as well as the maturation and coloring of crop fruits, the inventors of the present invention have found that the taste of amino acids is closely related to the size and hydrophobicity of side chain groups. When the hydrophobicity of the side chain groups of amino acids is relatively low, the amino acids mainly exhibit a sweet taste; for example, glycine, aspartic acid, alanine, serine, proline and the like have no repellent or anti-feeding effect on birds. When the hydrophobicity of the side chain groups of amino acids is relatively high, for example, phenylalanine, leucine, isoleucine, valine, tryptophan, arginine, histidine, tyrosine and the like can stimulate the taste buds of birds to produce a bitter taste, thereby blocking the feeding of birds and exerting a bird repellent effect. To this end, the present inventors have already filed an invention patent (CN115316390A).
[0004] Further research has shown that complexes formed by coordination bonds between amino acids and specific metals not only have a superior bird-repellent effect than the amino acids themselves, but can also repel a wider variety of birds, particularly large birds such as domestic and wild chickens, for which amino acids alone are insufficiently effective. Even amino acids that have little bird-repellent effect on their own, such as glycine, aspartic acid, and alanine, can effectively deter birds from feeding after forming metal complexes.
[0005] Conventional technologies do not describe the use of amino acid metal complexes as bird repellents. [Overview of the project] [Problems that the invention aims to solve]
[0006] In response to the aforementioned problems, the present invention aims to provide the use of a bird repellent in the production of an amino acid metal complex in order to solve the problem that existing bird repellents pose a potential harm to the biological environment. [Means for solving the problem]
[0007] The technical solutions employed by the present invention to solve the above technical problems are as follows:

[0016] The beneficial effects are as follows: Compared to the prior art, this invention can repel a wider variety of birds by treating crop seeds or fruits with a bird repellent manufactured using amino acid metal complexes as the active ingredient, and amino acids that did not have bird repellent properties on their own can effectively repel birds after forming metal complexes. When used at the recommended dose, it can effectively reduce the consumption and damage to crop seeds and fruits by birds without harming the birds. Bird repellents manufactured using amino acid metal complexes as the active ingredient are not only safe for humans and animals, convenient to use, and low cost, but they can also promote the growth and development of crop seeds, seedlings, and fruits, and increase agricultural production and farmers' income. [Modes for carrying out the invention]
[0017] The present invention will be described in more detail below with reference to specific examples, but the embodiments of the present invention are not limited thereto, and process parameters not specifically mentioned can be carried out according to conventional methods.
[0018] Unless otherwise specified, the technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art in the field to which this invention pertains. All units indicating the content of raw materials are expressed in parts by mass. Other raw materials and reagents in this invention, unless otherwise specified, refer to raw materials and reagents commonly used in the art.
[0019] This invention provides the following technical solutions to address the problems of existing bird repellents, such as unstable bird repellent effects, high usage rates, high costs, unsafeness to humans and animals, or unfriendly to the ecological environment.
[0020] Our research has shown that complexes formed by coordination bonds between amino acids and specific metals not only have a superior bird-repellent effect compared to amino acids alone, but can also repel a wider variety of birds, particularly large birds for which amino acids alone are insufficiently effective, such as domestic and wild chickens. Amino acids that themselves have little bird-repellent effect, such as glycine, aspartic acid, and alanine, can also effectively repel birds after forming metal complexes.
[0021] In the prior art, amino acid metal complexes, which are normally used as nutrients for humans, animals, and plants, are used as bird repellents. The amino acids are not limited to glycine, aspartic acid, phenylalanine, methionine, arginine, leucine, isoleucine, lysine, glutamic acid, threonine, serine, proline, valine, tryptophan, tyrosine, cysteine, alanine, and histidine, and the metals are not limited to zinc, manganese, magnesium, iron, copper, and calcium. In the present invention, when amino acids complex with metals, two different amino acids may complex with one metal, or one amino acid may complex with two or more metals.
[0022] Based on the same inventive concept, the present invention further provides pharmaceutical formulations. The active ingredient of the pharmaceutical formulation is an amino acid metal complex. As can be easily understood, the amino acid metal complex includes, but is not limited to, complexes formed by coordination bonds between amino acids such as glycine, aspartic acid, phenylalanine, methionine, arginine, leucine, isoleucine, lysine, glutamic acid, threonine, serine, proline, valine, tryptophan, tyrosine, cysteine, alanine, and histidine and metals such as zinc, manganese, magnesium, iron, copper, and calcium.
[0023] It can be formulated into various dosage forms according to usage requirements. The aforementioned dosage forms include, but are not limited to, suspension concentrate (SC), suspoemulsion (SE), oil-in-water emulsion (EW), microemulsion (ME), microcapsule suspension (CS), oil-based suspension (OD), emulsifiable concentrate (EC), soluble liquid (SL), water-soluble granule (SG), soluble powder (SP), water-dispersible granule (WG), wettable powder (WP), dustable powder (DP), granule (GR), flowable concentrate for seed treatment (FS), emulsion for seed treatment (ES), solution for seed treatment (LS), water-dispersible powder for seed treatment (WS) and dry powder for seed treatment (DS). By formulating the agent into various dosage forms, it can adapt to different usage environments and meet various application needs.
[0024] In this example, the weight percentage of the amino acid metal complex in the pharmaceutical preparation can be 1%~10%, 10%~20%, 20%~30%, 30%~40%, 40%~50%, 50%~60%, 60%~70%, 70%~80%, 80%~90%. Illustratively, the weight percentage of the amino acid metal complex in the pharmaceutical preparation is 10%~50%. By controlling the content of the amino acid metal complex at 10%~50%, a good bird repellent effect can be obtained, and at the same time, the usage amount of the amino acid metal complex can be reduced, thereby reducing the cost of the agent.
[0025] Hereinafter, the above technical solutions provided by the present invention will be further described with reference to specific examples.

The manhole cover of the shearing kettle was opened, the shearing machine was operated for 10 minutes, then the required amino acid metal complex (glycine manganese complex) was fed into the shearing kettle, sheared for a while, and then the shearing machine was stopped. The kettle bottom valve of the shearing kettle was opened, the cooling water valve of the bead mill was opened to maintain the circulation of cooling water, the bead mill was started to perform bead milling treatment twice, the material after bead milling treatment was transferred to the post-shearing kettle for shearing, and the qualified product obtained from sample analysis was discharged and filtered to obtain the amino acid metal complex seed treatment suspension.
[0028] Formulation Example 3 (Wettable Powder WP) The necessary amino acid metal complex (isoleucine calcium complex), 8.00% sodium ligninsulfonate, 2.00% sodium lauryl sulfate, and 7.00% sodium methylenedinaphthalenesulfonate were sequentially added to a stirring vessel. Kaolin was added to bring the total volume to 100%, and stirring was started. The mixture was stirred for 1.5 hours until it was completely homogeneous. The mixture was then pulverized using an air jet pulverizer, and the pulverized material was stirred and mixed for another 1.5 hours. Based on the results of sample analysis, the amino acid metal complex wettable powder was obtained from the samples that passed the test.

The mixture was then pulverized using an air jet granulator, and the pulverized material was stirred and mixed for a further 1.5 hours. Sample analysis was performed, and only those that passed the test were discharged. The material was then transferred to a fluid bed granulator, and granulation was started. The uniformity of the particles was observed during the granulation process. Once the particles were uniform, a sample was taken and tested. The result was that the sample that passed the test was obtained as amino acid metal complex granular wettable powder.
[0030] Examples of biometric measurements: The following examples show that the inventors raised spotted pigeons (Spilopelia chinensis) (as a substitute for magpies), white-rumped mukauna (Lonchura striata) (as a substitute for sparrows), domestic chickens (Gallus domesticus), and wild chickens (Phasianus colchicus) in an artificial greenhouse and evaluated the rate of feeding inhibition by a bird repellent containing an amino acid metal complex as an active ingredient. Feed inhibition rate = (Feeding rate of birds on blank control crop - Feeding rate of birds on treated crop) / Feeding rate of birds on blank control crop × 100% Biological Measurement Example 1 Rice seeds were treated with a 10% amino acid metal complex suspension at various doses, and the rate of feeding inhibition was calculated based on the amount of rice seeds consumed by birds.
[0031] Table 1, 10% SC feeding inhibition rate of amino acid metal complexes [Table 1]
[0032] Biological Measurement Example 2 Rice seeds were treated with a 40% amino acid metal complex seed treatment suspension at various doses, and the rate of feeding inhibition was calculated based on the amount of rice seeds consumed by birds.
[0033] Table 2, Amino acid metal complex 40% FS feeding inhibition rate [Table 2]
[0034] Biological Measurement Example 3 Rice seeds were treated with a 25% hydrated amino acid metal complex diluted with an appropriate amount of water at various doses, and the feeding inhibition rate was calculated based on the amount of rice seeds consumed by birds.
[0035] Table 3, Amino acid metal complex 25% WP feeding inhibition rate [Table 3] Biological Measurement Example 4 Rice seeds were treated with a 50% amino acid metal complex granular wettable powder diluted with an appropriate amount of water at various doses, and the feeding inhibition rate was calculated based on the amount of rice seeds consumed by birds.
[0036] Table 4, Inhibition rate of feeding by amino acid metal complex 50% WG [Table 4]
[0037] The data from the above biological measurement examples clearly shows that when seeds are treated with 2 grams / kilogram of the active ingredient in the amino acid metal complex, feeding inhibition rates of over 80% are observed in white-rumped mukauna, spotted pigeon, domestic chickens, and wild chickens, demonstrating its ability to provide an effective bird repellent effect on crop seeds. When seeds are treated with 4 grams / kilogram of the active ingredient in the amino acid metal complex, feeding inhibition rates for white-rumped mukauna, spotted pigeon, domestic chickens, and wild chickens all reach over 90%. At the same dose of active ingredient, the feeding inhibition rate of the amino acid metal complex in birds, especially large birds such as domestic chickens and wild chickens, is significantly higher than that of the same type of amino acid.
[0038] As described above, the present invention provides the use of a bird repellent in the production of an amino acid metal complex, wherein the amino acid is one or more of glycine, aspartic acid, phenylalanine, methionine, arginine, leucine, isoleucine, lysine, glutamic acid, threonine, serine, proline, valine, tryptophan, tyrosine, cysteine, alanine, and histidine, and the metal is one or more of zinc, manganese, magnesium, iron, copper, and calcium.
[0039] This invention provides a bird repellent manufactured using an amino acid metal complex as an active ingredient. By treating crop seeds with this repellent, it effectively reduces the consumption of crop seeds by birds, providing a clear protective effect. The bird repellent containing the amino acid metal complex as an active ingredient has a repellent and consumption prevention effect against common birds at a very low active ingredient dose (2 grams / kilogram of seeds). When used at the recommended dose, it is not only harmless to birds and safe for humans and animals, but is also convenient to use, low-cost, and can further promote the growth and development of crop seeds, seedlings, and fruits, thereby increasing agricultural production and farmers' income.
[0040] The above describes the basic principles, main features, and performance advantages of the present invention. It should be understood that the performance and use of the present invention are not limited to the examples given above, and those skilled in the art may make improvements or modifications based on the above description, and all such improvements and modifications shall also fall within the scope of protection of the appended claims of the present invention.
