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 . In the past, it was 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 declining, eventually leading to the emergence of “super bacteriaâ€. 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antibiotics (listed as “prescription drugsâ€), the future of streptomycin is worrying, and most of them have withdrawn from the market and are basically invisible.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 chunleimycin
There are 123 pesticide registration certificates in China, one of which is the original drug , 76 is a single agent, and 46 are mixed preparation certificates. The registered crops are widely used in fruit trees, vegetables and rice. It is more extensive, has certain control effects on bacteria and fungi, and has a good market prospect.
It has slight phytotoxicity to soybeans, grapes, citrus, apples, etc. It should be noted when using it in the adjacent soybean fields. It is non-toxic, non-residual and non-polluting to humans and animals. It meets the requirements of modern environmental protection and is suitable for the production of green and pollution-free food.
3 neutrophin
Zhongshengcin has a total of 34 pesticide registration documents in China, including 1 parent drug, 13 single agents, and 20 compounded preparation certificates. The patented technology of neutrophin is rapidly growing in China. It is an agricultural antibiotic that is currently limited to the control of bacterial diseases of crops. It has the same mechanism of action as streptomycin. The agricultural antibiotics prepared by biological fermentation are completely water-soluble.
Tested at home and abroad, it can kill and inhibit more than 99.95% of phytopathogenic bacteria; no sensitive plants have been found at present, the compounding is convenient, the application method is flexible, spray, soaking seeds and roots can be used; neutrophins are prevention and treatment One of the most promising and competitive agricultural antibiotics for plant bacterial diseases.
4 tetramycin
Tetramycin is a patent of Liaoning Weike Bio-engineering Co., Ltd. Currently, there is one parent drug registration certificate, two single-agent registration certificates, and two compound preparation registration certificates. Heilier is already registering products 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)
According to relevant information, Zhejiang Longwan Chemical Co., Ltd. produces 95% of the original product of leaf cumin. 20% folate WP, 500-fold diluted spray, is effective against rice bacterial leaf streak and bacterial blight. Due to the registration time on rice for more than 20 years, rice has developed a great resistance, and the effect of leaf rotazole control is declining. 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 28 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
Copper hydroxide has 30 registration documents in China, mostly single agents. It has not been registered on rice. It is widely registered in cash crops such as vegetables (cucumber, pepper and watermelon), fruit trees (citrus, grapes and lychee) 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 distinguish, and the market is extremely chaotic.
8 Wang Tong
Wang Tong currently has 20 enterprises and 40 registration documents registered in China, mostly for compounding, and only 12 single-agent certificates. Registered crops are extensive and there are many targets for prevention and treatment. 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 thiocarbamate fungicides.
9 Bordeaux mixture (basic copper sulphate, copper sulphate)
Bordeaux mixture, copper sulphate and basic copper sulphate are similar products. The content and purity are different. At present, there are 5 single-agent registration certificates for Bordeaux liquid, 5 calcium sulphate original drugs and 5 single-agent registration certificates. 14 copper registration 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 Thienson Copper
Thiosen Copper is a patent of Zhejiang Dongfeng Chemical Co., Ltd., which belongs to pesticides with independent intellectual property rights. At present, there is one original drug registration certificate and two preparation registration certificates in China. 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
