How to treat bacterial diseases?

As we all know, fruit and vegetable diseases can be roughly divided into: bacterial diseases, fungal diseases, physiological diseases, and viral diseases
.
For bacterial diseases, commonly used agents can be divided into the following categories.
According to the public information of China Pesticide Information Network, technicians inquired about the registration status of related compounds, and based on market feedback and industry insiders’ introductions, they made a simple market for the following agents Analysis
.
1.
The registration of agricultural streptomycin was cancelled in June 2016.
There are only 3 registration certificates of 3 companies in China.
At present, relevant information is not available 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, resistance to antibiotics has been continuously enhanced, and the prevention and treatment effect has also been declining, which eventually led to the emergence of "super bacteria"
.
Due to the country's strict management of agricultural antibiotics (listed as "prescription drugs"), the future of streptomycin is worrisome.
Most of them have already withdrawn from the market and are basically invisible
.
2.
Kasugamycin has 118 pesticide registration certificates from 58 companies in China, 76 of which are single-agent and 42 mixed certificates.
The registered crops are extensive, and they are applied to fruit trees, vegetables and rice.
The sterilization spectrum is relatively wide, and it is resistant to bacteria.
Both fungi have a certain control effect and have good market prospects
.
It has slight phytotoxicity to soybeans, grapes, oranges, apples, etc.
It should be used in neighboring soybean fields.
It is non-toxic, non-residual, and non-polluting to humans and animals, meets modern environmental protection requirements, and is suitable for the production of green and pollution-free food
.
3.
Zhongshengmycin currently has 34 pesticide registration certificates, 14 of which are single-agent and 20 mixed certificates.
The patented technology of Zhongshengmycin is growing rapidly in China, and it is currently limited to agricultural antibiotics for the prevention and control of crop bacterial diseases.
Streptomycin has the same mechanism of action.
It is an agricultural antibiotic substance produced by fermentation from a biological source.
It is completely water-soluble.
It can kill and inhibit more than 99.
95% of phytopathogenic bacteria according to domestic and foreign tests.
No sensitive plants have been found so far.
Convenient dispensing, flexible application methods, spraying, dressing, soaking, and root irrigation are all possible; Zhongshengmycin is one of the most promising and competitive agricultural antibiotics for the prevention and control of plant bacterial diseases
.
4.
Tetramycin is a patent of Liaoning Weike Biotech.
At present, there are 1 original drug registration certificate, 2 single doses, and 1 compound preparation registration certificate.
Hailier is already in the process of product registration and is expected to issue the certificate soon
.
Common tetramycin preparations include four major antibiotics, A1, A2, B and C.
The four active ingredients are complementary, and the bactericidal effect can be doubled, and the control effect on bacterial diseases is particularly outstanding! At the same time, it also has a strong killing effect on fungal diseases.
It has a broad market prospect and great development potential
.
5.
Thiacumazole (Ecuizole) No relevant information can be found on the China Pesticide Information website.
According to relevant data, Zhejiang Longwan Chemical produces 3 tons of 95% Yecuizole daily
.
20% Yekuizole WP, 500 times dilution spray on rice, is effective for controlling rice bacterial streak and bacterial leaf blight
.
Since it has been registered on rice for more than 20 years, rice has developed great resistance to pesticides, and the control effect of ecumazole is declining
.
Because there are too many registered enterprises, market competition is disorderly, prices are very chaotic, and they gradually lose their original status and are already in decline
.
6.
Ethylicin has 27 registration certificates in China, with a wide range of registered crops, and has a certain control effect on bacteria and fungi.
It is also a relatively common agent for the prevention and treatment of bacterial diseases
.
7.
There are 22 domestic enterprises with 30 registration certificates of copper hydroxide, most of which are single agents.
They have not been registered on rice.
They are registered on cash crops such as vegetables (cucumbers, peppers and watermelons), fruit trees (citrus, grapes and lychees) and tobacco.
Widely used, it is a common inorganic copper preparation for preventing and curing bacterial diseases of vegetables
.
It is more sensitive in the flowering and young fruit period.
It should not be mixed with acidic pesticides and should be sprayed separately
.
Among them, the mixture with kasugamycin is sensitive to the tender leaves of crops such as apples, grapes, soybeans, and lotus roots.
Therefore, it is necessary to pay attention to the concentration and spray after 4 pm
.
Due to the large number of registered companies, the price disparity is large, it is difficult to tell the truth and the market is extremely chaotic
.
8.
There are 40 registration certificates for 20 Wangtong companies, most of which are compound, and there are only 12 single-agent certificates
.
There are a wide range of registered crops, and there are also many control objects
.
It is sensitive to the tender leaves of crops such as apples, grapes, soybeans, and lotus roots.
Therefore, you must pay attention to the concentration and spray after 4 pm
.
Can not be mixed with thiocarbamate fungicides
.
9.
Bordeaux solution (basic copper sulfate, copper calcium sulfate) Bordeaux solution, copper calcium sulfate and basic copper sulfate are similar products, with different content and purity.
Currently, there are 5 Bordeaux solution certificates and 5 copper calcium sulfate certificates.
There are 14 basic copper sulfate certificates
.
Basic copper sulfate is industrially produced, and the copper ion content is 2.
9 times that of conventional Bordeaux liquid (copper calcium sulfate), which is cost-effective
.
Since the finished formulations are mostly neutral, the compounding properties are very good, it is a very cost-effective compound, and there is no resistance, the prospect is very good
.
10.
