"Complete solution" for bacterial diseases in crops (Bacterial disease control technical regulations)
Bacterial diseases are diseases caused by bacterial infections, such as soft rot, ulcer disease, and bacterial wilt. The bacteria that invade the plants are rod-shaped bacteria. Most of them have one or several flagella, which can be invaded by natural wounds (stomas, lenticels, water holes, etc.) and are transmitted by flowing water, rainwater, insects, etc. , seeds, winter in the soil, easy to disease under high temperature and high humidity conditions. Symptoms of bacterial diseases are wilting, rot, perforation, etc. In the late onset of the disease, wet weather occurs, and bacterial mucus overflows from the diseased area, which is a characteristic of bacterial diseases.
Bacterial diseases are important diseases that affect China's agricultural production.
Bacterial streak of rice bacterial blight is one of the three major diseases of rice. China has an annual area of ​​more than 10 million mu, which generally reduces production by 10%-20%, and severely reduces production by 50%.
Citrus canker disease is the main disease of citrus. It occurs widely and seriously affects the yield and quality of citrus.
Ginger disease can prevent ginger from being planted again, seriously affecting the economic development of ginger growing areas.
At present, there are relatively few types of pesticides used to control bacterial diseases in agricultural crops compared to those used in the prevention and treatment of fungal diseases. Existing pesticides such as agricultural streptomycin, Yeqingshuang and inorganic copper preparations (copper hydroxide, copper sulfate, Copper oxychloride and cuprous oxide) and other agents generally have poor control effects.
Zhejiang Longwan Chemical Co., Ltd. independently invented and invented a new pesticide species - 20% Longkei (TB) copper suspension agent, with independent intellectual property rights, is China's patented invention products, national key new products, the Ministry of Agriculture to promote pesticide products, China The “Technical Inventions First Prize†products in the petrochemical industry and the “key promotion of pollution-free pesticides†in the 18 provincial plant protection and phytosanitary stations nationwide.
The bronchobacilli (thiacax) are composed of thiazole groups and copper ions, have strong endogenous transduction properties, have dual effects of treatment and protection, are advanced in dosage form, are reasonable in use cost, and are easily accepted by farmers. At the same time, 20% bronchobacilli (thiaca copper) suspension agent is safe to humans, livestock, and natural enemies, and has good compatibility with the environment.
The use of dragon's fungus (thiacax) in the prevention and treatment of bacterial diseases must adhere to the concept and program of "full-process drug use". From the seed stage to the seedling stage, transplanting stage and field stage, all drugs must be adhered to. The three major chronic diseases such as bacterial diseases, soil-borne diseases, and root diseases are completely resolved. If you only use the medicine at the beginning of the disease, it may be unsatisfactory because of temporary symptoms.
The dragon's fungus (thienobacterium copper) is a kind of “fool pesticide†and can be applied by seed soaking, seedling pouring, soil disinfection, transplanting roots, field irrigation and spraying, and at the same time During the period, seedling stage, seedling stage, transplanting stage, flowering stage, young fruit stage, and early stage of disease, medicines can be used without fear of injury, and there is no need to worry about the problem of mixing with other pesticides.
The dragon's bacterium (thiacacil copper) is synthesized through the “three-step reaction methodâ€. After 8 years of research, the production process is very mature and advanced formulations such as suspension agents have been developed. At present, the dragon's fungus (thiacax) has entered the large-scale application and sales stage. Field demonstration experiments show that 20% of the bacterium Dragon's fungus is a highly effective, low-toxic, safe thiazole organic copper killer. Bacterial agents.
20% Longkei (Toxicillin copper) suspension agent, mainly used for the control of rice bacterial leaf blight, bacterial leaf streak disease, cabbage soft rot, citrus canker disease, ginger ginger scab, cucumber bacterial leaf spot and other crops Bacterial diseases can also control fungal diseases such as citrus scab, watermelon wilt, and banana leaf spot.
Application conditions: 20% bronchobacilli (thiaca copper) suspension agent, field use concentration of 500 to 700 times. The amount of mu for controlling bacterial blight and bacterial leaf blight of rice is 100 g. Bacterial leaf blight and Bacterial leaf blight of rice were soaked with 20% bronchospirillum (Ticonium copper) suspension seeds and sprayed on the field for one time. The field was sprayed one or two times at the initial stage of onset.
The use of a concentration of 500 to 700 times spray to prevent bacterial bacterial leaf spot disease and other bacterial diseases.
Prevention and control of soft rot of Chinese cabbage with 600 times liquid irrigation, control efficiency up to 80%.
The prevention and treatment of citrus canker is aimed at protecting young shoots and fruits, and spraying protection is started at the spring shoots, summer shoots and autumn shoots.
The soil-borne bacterial diseases such as ginger aphid are combined with control measures such as soaking with ginger and irrigation.
The other root diseases were combined with irrigation and splashing. The use of 20% Longkei (Toxicillin copper) suspension concentrate was mainly for treatment and protection, and it was applied at the initial stage of crops.
Operational procedures: The prevention and treatment of bacterial diseases, including soil-borne diseases and root diseases, should be carried out from the seed stage to the seedling stage, transplanting stage, and field stage, and the “full-process drug application†scheme should be implemented, combining multiple application methods. Do not completely hope to apply drugs at the beginning of the disease.
Roncobacter (thienobacterium copper) is an ideal agent for the prevention and treatment of bacterial diseases. Roncobacter (thienobacterium copper) is a specialist in the control of bacterial diseases.
