* Seed coating agent, as the name implies, is the agent that dresses the seeds. It is a seed treatment agent made from pesticides (insecticides, fungicides), trace elements, sustained-release agents, and film-forming agents and other active ingredients and additives.
Focus: (a) Nine physicochemical traits of seed coating agents ("Seed Processing Science Principles and Technology" 255-257). * Film formation time.
(B) General knowledge of pesticides and commonly used seed coating agents (is a special type of pesticide products)
1. * "Three Certificates" of pesticides: Refers to pesticide production permit, pesticide standards and pesticide registration certificate. The "three certificates" of pesticides are issued in units of products, that is, each pesticide product and the same pesticide product produced by different manufacturers have their own three certificates. Each commercialized pesticide product of each pesticide company must have three numbers of three certificates, three different certificates, or three certificates of other pesticide products, or fraudulent use of other certificates from other manufacturers. The scope of counterfeiting and counterfeiting is an illegal act. A pesticide product has three certificates, not according to the technical requirements stipulated in the three certificates, product quality can not meet the relevant requirements of the three certificates, the product is inferior and defective, resulting in adverse consequences, the manufacturer must bear legal responsibility.
2. Toxicity and lethality of pesticides (see Principles and Techniques of Seed Treatment, pp. 119-121)
3. Commonly-used pesticide ingredients in seed coating agents (see Principles and Techniques of Seed Processing Science, pp. 200-238)
* Active ingredient content and nomenclature of seed coating agent.
5 types of insecticides: phorate, methylisohexose, phoxim, gram and acephamide; fungicides: * non-absorbable fungicides 4: thiram, mancozeb, 100 Bacterial Chloride, Pentachloronitrobenzene; *9 Systemic Bactericides: Metalaxyl, Tolclofos-methyl, Carbendazim, Versitile, Seedling, Triadimenol (keto), Dexon Welfare double.
(1) Metalaxyl: Also known as Aplon, Rhizoctonia. This variety was developed in 1977 by the Swiss Ciba Gage. There is 35% seed treatment (ie Aplon). Low toxicity to humans and animals, acute oral LD50 in rats is 669MG/KG, mildew and disease in rats.
(2) Tolcadophos-methyl: This product was developed by Sumitomo Chemical Co., Japan and FBC, UK. Is a systemic fungicide. Low toxicity to humans and animals, the rat's acute oral LD50 5000mg/kg, rat acute dermal LD50 greater than 5000mg/kg, relatively safe for humans and animals. It has strong bactericidal activity against pathogens such as seedling blight and sclerotinia. Its strong sucking effect, not easy to lose, in the soil for a longer period of validity. 100kg cotton seeds are used 200-300g. It is also effective against quinophthalein to produce antibiotic blight.
(3) Triadimenol: Triadimenol, also known as trachymantin, bantam. In the study of the metabolism of triadimefon in vivo, Triadimefon was found to convert triadimefol in both pathogens and plants, and the tribendrazol has a higher bactericidal activity than triadimefon, resulting in triazole in 1977. Alcohol is developed as a commodity. The bactericidal spectrum of triadimenol is almost the same as that of triadimefon, which has protection, eradication, and therapeutic effects on the disease. Can kill the pathogen attached to the seed surface, but also can kill the pathogen inside the seed. Triadimenol is used to treat seeds. At very low doses, it has excellent control effects on crop seed and pathogens. It is an important feature of triadimenol, smut, root rot, and barley. , ooze scattered smut, 100kg seeds, with active ingredients 7.5g-15g (15% wettable powder 75-150g) treatment, wheat rust, 100kg seeds with 10% wettable powder 150-180g (ie active ingredients 15-18g) treatment. Triadimenol treatment of wheat seeds, similar to triadimefon, has a certain inhibitory effect on the growth of seedlings. Its inhibition strength is related to the degree of pesticide application, and is also much lighter than triadimefon, and does not substantially affect the middle and late stages of wheat. The growth and yield. The use of triadimefol in seed dressings to control corn and sorghum smuts is not stable, and fluctuations between the end of the year and the region are significant and should not be used.

In addition, the use of Weifu and coated seeds has a small increase in water content. Apart from not controlling pests, there are four benefits. First, the cost is lower. Second, the use of drugs is small, and the water content of the coating seeds is small and can be achieved. The coating and metering process is mechanized and automated. The third is that foreign seed coating agents have extremely low toxicity and some are lower than salt (such as Weifu's acute lethal oral medium dose is 6250mg/kg, and salt's acute lethal oral medium dose is 3320mg/ Kg), for human and livestock safety, environmental pollution is small, four is a good quality of pharmaceuticals (such as Wei Fu four years without precipitation), uniform coating.

3 Control objects: Weifu is a fungicide with both internal absorption and contact toxicity. After the seeds are coated, they are protected both inside and outside, and comprehensively prevent seedling disease, soil-borne diseases, and species-borne diseases. For example, in the fungus period, the control effect against blight, stem rot, anthrax, and damping-off disease is very good. Because of its internal absorption, it can also prevent other non-seedling diseases such as smut, smut, black embryo disease, leaf spot disease, and streak disease. Prevention of bad species. Control wheat rust and mildew.
