Technical Field
The invention belongs to the technical field of chemical bird repellent, and particularly relates to application of thiocyanuric acid in preparation of a bird repellent.
Background
With the improvement of ecological environment quality, the phenomena of agricultural yield reduction and farmer yield reduction caused by the great consumption of crop seeds and fruits by birds are more and more serious, and how to properly protect the crop seeds and fruits on the premise of not damaging the birds has become a great agricultural problem.
The agricultural bactericide 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 formally banned thiram in 2018, because thiram has higher acute toxicity to users, higher risks to birds, mammals and aquatic organisms, and potential risks of endocrine disruptors. In addition, the thiram metabolite may form N, N-dimethyl Nitrosamine (NDMA) in water, which may be harmful to water.
Thiocyanuric acid (Trithiocyanuric acid, CAS number 638-16-4) is generally used as a pharmaceutical intermediate, a heat stabilizer for high 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 thiocyanuric acid as a bird repellent.

Detailed Description
The present invention will be described in further detail with reference to the following specific examples, but embodiments of the present invention are not limited thereto, and may be performed with reference to conventional techniques for process parameters that are not specifically noted.
Unless otherwise defined, 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 representing the content of the raw materials are all calculated in parts by mass. Other raw materials and reagents not specifically mentioned in the present invention are those commonly used in the art.
The invention provides the following technical scheme for solving the problems of large dosage and unfriendly ecological environment of the existing bird repellent:
the thiocyanuric acid which is usually used as a medical intermediate, a heat stabilizer for high polymers such as polypropylene and rubber, a vulcanizing agent for chlorinated ethyl acrylate-ethylene polymers and polymers such as acrylic rubber in the prior art is used as a bird repellent. As a known raw material, thiocyanuric acid is known in its molecular structure, that is, the safety of the raw material is clear and known.
In the embodiment, because the thiocyanic acid can stimulate throat nerves of birds, when the birds grippers eat the seeds treated by the thiocyanic acid, the throat nerves are stimulated to promote the birds to spit the seeds, so that the birds can be prevented from taking the seeds, and the effect of expelling birds is achieved. Meanwhile, the thiocyanuric acid has good stability in an environment with certain humidity, so that the thiocyanuric acid is prepared into the bird repellent agent, the bird repellent agent is coated on the surface of seeds, a protective layer is formed on the surface of the seeds, and after the seeds are sown, bird repellent aging can be prolonged, and the use cost is reduced.
Based on the same inventive concept, the invention also provides a pharmaceutical preparation, wherein the active ingredient of the pharmaceutical preparation is thiocyanic acid.
Various dosage forms may be formulated according to the use requirements, including but not limited to: suspending agents (SC), suspoemulsions (SE), aqueous Emulsions (EW), microemulsions (ME), microencapsulated suspending agents (CS), oil suspensions (OD), emulsifiable Concentrates (EC), soluble Solutions (SL), water dispersible granules (WG), wettable Powders (WP), powders (DP), granules (GR), seed treatment suspending agents (FS), seed treatment Emulsions (ES), seed treatment solutions (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 administration requirements can be met.
In this embodiment, the thiocyanuric acid 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% by weight of the pharmaceutical formulation. Illustratively, the thiocyanuric acid accounts for 20-50% of the pharmaceutical preparation by weight, and the content of the thiocyanuric acid is controlled to be 20-50%, so that the bird can be kept away, and the drug effect of the bird can be maintained until the seed germinates (usually, the bird cannot dig after the seed germinates). That is, the use amount of the thiocyanuric acid can be reduced while a better bird repellent effect is obtained, and the cost of the medicament can be further reduced.
