At present, once a major outbreak of bacterial diseases in crops is caused by the lack of efficient, low-toxicity, broad-spectrum symptomatic pesticides, they are often prevented from being produced in time, often resulting in reduced yields of vegetables, resulting in failure of rice or even crops, and affecting the fruit yield and quality of fruit trees.
At present, there is still a lack of variety resources at home and abroad that can effectively prevent and control bacterial diseases in crops.
In the prevention and control of bacterial diseases in rice, the only drug used in recent years is methamphetamine. According to the research results of Nanjing Agricultural University, bacteria of rice bacterial blight are easily resistant to the drug, and bacterial streak disease has a similar situation. Therefore, in recent years, the drug efficacy of various forms of metformazole has been poor, and the condition of the disease has not been effectively controlled.
In a variety of fruit tree bacterial diseases, especially citrus, our country commonly used domestic and imported inorganic copper fungicides, such as copper hydroxide, cuprous oxide, copper sulfate and copper oxychloride, etc. Unsatisfactory, a large amount of time prone to phytotoxicity and induce the recurrence of fleas such as proliferation.
In the case of bacterial diseases of vegetables, there is no good chemical control. The conventionally abused streptomycin in agriculture has poor field efficacy and is very resistant to drugs. The disease is still not effectively controlled.
The successful creation of thienobacterium copper solves the problem of prevention and control of bacterial diseases, thus finding a new method for the prevention and treatment of bacterial diseases.
Longke Microorganism Suspension (Thiococcus copper) produced by Zhejiang Longwan Chemical Co., Ltd. provides a new approach for the prevention and treatment of bacterial diseases. Thiobacillus (Loncobacter) is now listed as a national key new product and promotion variety, and is a pesticide species produced by pollution-free agricultural products recommended by the Ministry of Agriculture. Thiobacillus (Loncobacter) is a new type of bactericide with high efficiency, low toxicity, low residue, safety and environmental protection.
The product name “Lonker†belongs to the pesticide with independent intellectual property rights, the generic name is “Thiococcus copperâ€, the molecular formula is C4H4N6S4Cu, the molecular weight is 329, the English generic name is thiodiazole-copper, and the chemical name is “2-amino- 5-mercapto-1,3,4-thiadiazole-copper", Zhejiang Longwan Chemical Co., Ltd. is an exclusive producer of new bactericidal preparations at home and abroad, and has been listed in the national "Eleventh Five-Year Plan" technology support project plan, the country Technological innovation projects, national key new products, the Ministry of Agriculture's key promotion of new products, the National Agricultural Technology Extension Technical Service Center "highly recommend new pesticides" and Zhejiang Province "high-tech products" and other honors and awards.
The novel, highly effective, and low-toxic new bactericide, Thiophen copper (Loncobacter), developed by Zhejiang Longwan Chemical Co., Ltd., has brought about the prevention and treatment of bacterial diseases of crops such as rice, citrus, fruits and vegetables. Gospel. Thiobacillus thaliana is a new bactericide which has the advantages of novel structure, good activity, high efficacy, broad bactericidal spectrum, low toxicity and advanced dosage form. It has solved the current domestic bacterial diseases lack of high-efficient medicaments. Prevention problems.
The following is a description of the use of Thiobacillus thuringiensis in the control of bacterial diseases in crops:
A. Thiobacillus (Loncobacteri) Whole-course drug plan:
1 Seed soaked at the seed stage of crops, soaked at a ratio of 1:50 for the weight ratio of seed to agent, sowed after sowing;
2 During the seedling stage of crops, use 600 times liquid to soak or roots or spray;
3 When the crops are transplanted, the seedlings are used for rooting and then colonized;
4 At the early stage of the bacterial disease of crops, use 100 microliters of copper (Lactococcus) suspension agent 100 ml of water 50-60 kg (500-600 times) fine spray per acre;
5 The bacterial diseases of the leaves and fruits of crops should be sprayed with 500 times of fine spray and the amount of spray should be more than 50 kilograms per mu.
6 Bacterial diseases in the roots or stem base of crops were treated with 500 times of rooting or rooting.
7 Soil-borne bacterial diseases of crops, irrigated 2-3 times with 600 times bronchobacilli (Thiococcus) liquid, each time about 7 days, adhere to medication, the control effect can reach 85%.
Second, the thiabendazole copper (Lactococcus) application details:
1. Appropriate period of application: Prevention should be the main method. Use of drugs before the onset of typhoon or early onset of disease is better.
If you miss the prevention of time caused by severe disease, can be used once every 7-10 days, continuous control 2-3 times, can significantly reduce the loss.
2. Shake well before use, if any precipitate should be shaken before use, but it does not affect the efficacy.
3. It can be mixed with various insecticides, acaricides and fungicides. However, it cannot be mixed with strong alkaline pesticides.
4. When used, use a small amount of water to make the mother liquor twice diluted, and then dilute the spray with water.
5. It is safe for flowering, seedling and young fruit and it is not easy to produce phytotoxicity. (Xiong Xingping) (0577-86636387)
