With the improvement of the quality of ecological environment, the phenomena of agricultural yield reduction and farmer income reduction caused by the fact that birds eat crop seeds and fruits in large quantities are more and more serious, and how to properly protect the crop seeds and the fruits on the premise of not damaging the birds becomes a great agricultural problem.
The agricultural fungicide Thiram (Thiram, CAS number: 137-26-8) is commonly used as seed treatment, soil treatment or spraying and is also a known bird repellent, but has the defects of large dosage and unstable repellent effect. The European union officially banned thiram in 2018 because of its high acute toxicity to users and high risk to birds, mammals and aquatic organisms, and also the potential risk of endocrine disruption. In addition, the thiram metabolite may form N, N-dimethylnitrosamine (NDMA) in water, which may cause harm to water.
Thiocyanuric acid (CAS number: 638-16-4) is commonly used as a medical intermediate, a heat stabilizer for polymers such as polypropylene and rubber, a vulcanizing agent for polymers such as chlorinated ethyl acrylate-ethylene polymer and acrylic rubber, and the like.
There is no disclosure in the prior art of the use of thio-cyanuric acid as bird repellent.

Detailed Description
The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto, and may be carried out with reference to conventional techniques for process parameters not particularly noted.
Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the units indicating the content of the raw materials are all in parts by mass. Other raw materials and reagents not specifically mentioned in the present invention are those generally used in the art.
The invention provides the following technical scheme for solving the problems of large dosage and unfriendliness to the ecological environment of the existing bird repellent:
the thiocyanuric acid which is commonly used as a medical intermediate, a heat stabilizer for high polymers such as polypropylene and rubber, and a vulcanizing agent for polymers such as chlorinated ethyl acrylate-ethylene polymer and acrylic rubber in the prior art is used as the bird repellent. Thiocyanuric acid is a known starting material whose molecular structure is known, that is to say the safety of which is clear and known.
In this embodiment, since thiocyanuric acid can stimulate throat nerves of birds, when the birds have been adept on the seeds treated with thiocyanuric acid, the throat nerves are stimulated to spit out the seeds, so that the birds can be prevented from eating the seeds, and the bird repelling effect is achieved. Meanwhile, the thiocyanuric acid has good stability in an environment with certain humidity, and the prepared bird repellent agent is coated on the surface of the seeds to form a protective layer on the surface of the seeds, so that the bird repellent time-effect can be prolonged and the use cost can be reduced after the seeds are sowed.
Based on the same inventive concept, the invention also provides a pharmaceutical preparation, wherein the active ingredient of the pharmaceutical preparation is thio-cyanuric acid.
Various dosage forms can be prepared according to the use requirements, and the dosage forms include but are not limited to: suspension Concentrates (SC), Suspoemulsion (SE), aqueous Emulsion (EW), Microemulsion (ME), microcapsule suspension (CS), oil suspension (OD), Emulsifiable Concentrates (EC), soluble Solutions (SL), water dispersible granules (WG), Wettable Powders (WP), powders (DP), Granules (GR), seed treatment suspension (FS), seed treatment Emulsion (ES), seed treatment liquid concentrates (LS), seed treatment dispersible powders (WS) and seed treatment dry powders (DS). The medicament is prepared into different dosage forms, so that different use environments can be met, and different application requirements can be met.
In this embodiment, the weight percentage of thiocyanuric acid in the pharmaceutical preparation may be 1% to 10%, 10% to 20%, 20% to 30%, 30% to 40%, 40% to 50%, 50% to 60%, 60% to 70%, 70% to 80%, 80% to 90%. Illustratively, the thiocyanuric acid accounts for 20-50% of the weight of the pharmaceutical preparation, and the content of the thiocyanuric acid is controlled to be 20-50%, so that the thiocyanuric acid can achieve the effect of avoiding birds and maintain the pesticide effect of the thiocyanuric acid until the seeds germinate (generally, the birds cannot dig after the seeds germinate). That is, the dosage of thiocyanuric acid can be reduced while a good bird repelling effect is obtained, and the cost of the agent can be further reduced.
