As we all know, greenhouse vegetable diseases can be broadly divided into: bacterial diseases, fungal diseases, physiological diseases, and viral diseases. For bacterial diseases, the commonly used drugs can be divided into the following types. According to the public information of China Pesticide Information Network, the technical staff of the association inquired about the registration status of related compounds, and based on market feedback and introduction by the industry, the following agents are made simple. Market analysis. 1. Agricultural streptomycin It was cancelled in June 2016. There are only 3 registration documents for 3 companies in China. Currently, no relevant information can be found on the China Pesticide Information Network. Streptomycin is the most common antibiotic fungicide . It used to be a traditional product for the prevention and treatment of bacterial diseases. In recent years, drug resistance has been continuously enhanced, and the control effect has been continuously reduced, eventually leading to the emergence of "super bacteria." Due to the state's strict management of agricultural antibiotics (listed as “prescription drugsâ€), the future of streptomycin is worrying, and most of them have withdrawn from the market and are basically invisible. 2, spring Leimycin There are 118 pesticide registration certificates in 58 enterprises in China, including 76 single agents and 42 mixed documents. The registered crops are widely used in fruit trees, vegetables and rice. The bactericidal spectrum is extensive and has certain bacteria and fungi. The control effect has a good market prospect. It has slight phytotoxicity to soybeans, grapes, citrus, apples, etc. It should be noted when using it in neighboring soybean fields. It is non-toxic, non-residual and non-polluting to humans and animals. It meets modern environmental protection requirements and is suitable for the production of green and pollution-free food. 3. Zhongshengmycin At present, there are 34 pesticide registration documents, 14 of which are single-agent, and 20 patented technologies of mixed-type documents are rapidly growing in China. They are agricultural antibiotics that are currently limited to the control of bacterial diseases of crops, and have the same effect as streptomycin. Mechanism, a complete agricultural source of antibiotics prepared by biological fermentation, with complete water solubility; Domestic and foreign tests can kill and inhibit more than 99.95% of phytopathogenic bacteria; no sensitive plants have been found at present, and the mixed drugs are convenient, the application method is flexible, spray, mixed soaking and rooting can be used; neutrophins are prevention and treatment One of the most promising and competitive agricultural antibiotics for plant bacterial diseases. 4. Tetramycin It is a patent of Liaoning Micro-Technology. At present, there is one original drug registration certificate, two single-agents, and one compound preparation registration certificate. Heilier has already registered the product and is expected to issue the certificate soon. The common tetramycin preparations include four major antibiotics, A1, A2, B and C. The four active ingredients are complementary, the bactericidal effect can be doubled, and the control effect on bacterial diseases is particularly prominent. At the same time, fungal diseases are also It has a strong killing effect, a multi-drug treatment, a broad market prospect and great development potential. 5, thiazolidine (leafazole) Relevant information has not been found on the China Pesticide Information Network. According to relevant information, Zhejiang Longwan Chemical Co., Ltd. produces 95% of the original product of leaf cumin. 20% folate WP, 500 times diluted spray on rice, is effective for controlling bacterial leaf streak and bacterial blight in rice. Due to the registration time on rice for more than 20 years, rice has developed a great resistance, and the effect of leaf rotazole is constantly decreasing. Due to too many registered enterprises, the market competition is disorderly, the price is very chaotic, and gradually lose its original status, which is already in a state of decline. 6, allicin There are 27 registration documents in China, which have a wide range of registered crops, and have certain control effects on bacteria and fungi. They are also relatively common agents for controlling bacterial diseases. 7, copper hydroxide There are 22 enterprises in China with 30 registration documents, mostly single agents. They are not registered on rice. They are widely registered in cash crops such as vegetables (cucumber, pepper and watermelon), fruit trees (citrus, grapes and litchi) and tobacco. An inorganic copper preparation for controlling bacterial diseases of vegetables. It is sensitive during flowering and young fruit, and should not be mixed with acidic pesticides. It should be sprayed separately. Among them, the mixture with chunleimycin is sensitive to the young leaves of apples, grapes, soybeans and alfalfa, so it is necessary to pay attention to the concentration, and it is advisable to spray after 4 pm. Due to the large number of registered companies, the price gap is large, the truth is difficult to argue, and the market is extremely chaotic. 8, Wang Tong There are 40 registration certificates for 20 companies, mostly for compounding, and there are only 12 single-agent certificates. There are a wide range of registered crops and a large number of control targets. It is sensitive to young leaves of crops such as apples, grapes, soybeans and alfalfa, so be sure to pay attention to the concentration. It is advisable to spray after 4 pm. Can not be mixed with thiourethane bactericide. 9, Bordeaux liquid (basic copper sulfate, copper calcium sulfate) Bordeaux liquid and copper sulphate calcium and basic copper sulphate are similar products. The content and purity are different. At present, there are 5 Bordeaux liquid documents, 5 copper sulphate certificates and 14 basic copper sulphate documents. The basic copper sulphate is industrially produced, and the copper ion content is 2.9 times that of the conventional Bordeaux liquid (copper sulphate), and the cost performance is high. Since the finished preparations are mostly neutral, the compounding is very good, and it is a compound with high cost performance. In addition, there is no resistance and the prospect is very good. 10, Thiessen copper It is a patent of Zhejiang Dongfeng Chemical Co., Ltd., which belongs to pesticides with independent intellectual property rights, 1 original drug registration certificate, and 2 dosage form registration certificates. The preparation has good effects on the control of common bacterial diseases of crops such as bacterial blight and bacterial stripe, tomato bacterial wilt, Chinese cabbage soft rot and citrus canker. 11, copper acetate Only one company in China produces the original drug, and the registration certificate has dropped from 78 to 2 years ago. The author is not optimistic about its prospects. The compounding (mixed) registration mainly deals with the prevention and treatment of viral diseases, and the single-agent registration of bacterial diseases is relatively small. 12, amber resin copper There are 12 registration documents for 12 enterprises in China, and the number of documents has been declining in the past two years. Registered crops and control objects are relatively extensive, and have certain control effects on bacteria and fungi. When used, the concentration of the liquid should not be too large, otherwise it may cause phytotoxicity. 13, copper rosinate There are 14 registration documents for 14 enterprises in China, and the number of documents has not increased in the past two years. Registered crops and control objects are relatively extensive, and have certain control effects on bacteria and fungi. 14, thiabium copper (Dragonella) Only one company in China produces the original drug and one registration certificate. An agent for bacterial diseases of cucumber bacterial leaf spot, fruit trees, fruits, flowers, rice, cotton, and tobacco. 15. Thiazole zinc It is a patent of Zhejiang Xinnong, with 2 original drug certificates and 3 product registration certificates. At present, only Zhejiang Xinnong Chemical is doing it. 16, chlorobromoisocyanuric acid There are 12 enterprises in China with 14 registration certificates, registered crops, and a wide spectrum of bactericidal spectrum. They have certain effects on diseases such as bacteria, fungi and viruses. They belong to the “Wanjin Oil†type of pesticides, but the market price is chaotic and the retail profits are low. The dealer lacks motivation. 17. Trichloroisocyanuric acid There are 5 registration certificates for 3 companies in China. It has certain control effects on diseases such as bacteria and fungi. Do not touch with acids or alkalis to avoid decomposition failure and explosive combustion. If the product is decomposed and burned by alkali or acid, it should be extinguished with sand and gravel or with chemical water-killing agent. 18, Bacillus polymyxa At present, there are 4 domestic manufacturers and 8 registration certificates, which are biological pesticides for controlling bacterial wilt and blight.
