Excellent fungicides are the most effective measures to prevent and control agricultural diseases. With the development of science and technology, many excellent pesticides are continuously introduced, making great contributions to the prevention and control of agricultural pests and diseases. Today I would like to introduce to you an excellent medicine that can prevent, treat and eradicate many diseases. This medicine is tebuconazole.
1. Introduction to pharmaceuticals
Tebuconazole is a triazole fungicide developed by the German company Bayer in 1995. It is a highly efficient, broad-spectrum, systemic triazole fungicidal pesticide with three major functions of protection, treatment and eradication. It has a wide bactericidal spectrum, long duration of effect, no resistance, versatile use, good mixability, and low price. It has become another excellent broad-spectrum fungicide after azoxystrobin and is very popular among farmers. It is widely used in crops, vegetables, fruit trees, Chinese medicinal materials, flowers and other aspects.
2. Scope of application
Tebuconazole is mainly used in wheat, rice, peanuts, soybeans, cucumbers, potatoes, watermelons, cantaloupes, tomatoes, eggplants, chili peppers, garlic, scallions, cabbage, cabbage, cauliflower, bananas, apples, pears, peaches, kiwifruit, grapes, citrus fruits, mangoes, lychees, longans, and other crops, as well as corn and sorghum. It has been registered and widely used on more than 60 crops in more than 50 countries worldwide. It is the most widely used fungicide at present.
3. Main features
(1) Broad bactericidal spectrum: Tebuconazole can be used to prevent and control dozens of diseases such as rust, powdery mildew, Fusarium head blight, brown spot, sheath blight, and root rot caused by fungi of the genera Powdery mildew, Rust rust, Corynebacterium, and Fusarium oxysporum, all of which have good protective, therapeutic, and eradication effects.
(2) Thorough treatment: Tebuconazole is a triazole fungicide. Mainly by inhibiting the biosynthesis of ergosterol of pathogenic bacteria, it achieves the effect of killing pathogens, and has the functions of protecting, treating and eradicating diseases, and treating diseases more thoroughly.
(3) Good mixability: Tebuconazole can be compounded with most bactericidal and insecticides, all of which have good synergistic effects. Some formulas are also classic formulas for disease prevention and control.
(4) Flexible use: Tebuconazole has systemic conductivity characteristics and can be used in various methods such as spraying and seed dressing. The appropriate method can be selected according to the actual situation.
(5) Growth regulation: Tebuconazole is a triazole fungicide. Triazole fungicides all have a common feature and can be used to regulate plant growth, especially for seed dressing. It can prevent seedlings from growing too much, making them stronger, more disease-resistant, and flower buds differentiate earlier.
(6) Long duration of effect: Due to its strong permeability and good systemic properties, tebuconazole can quickly penetrate into the crop body and exist in the body for a long time, achieving the effect of continuously killing pathogens. Especially for soil treatment, the duration of effect can reach more than 90 days, which greatly reduces the number of pesticide applications.
4. Prevention and control objects
Tebuconazole can be used to prevent and control dozens of diseases, including powdery mildew, rust, smut, smut, anthracnose, stem blight, sheath blight, stem rot, root rot, leaf spot, black spot, brown spot, ring rot, leaf drop , net spot, rice blast, rice smut, black spot, stem rot, and other diseases.
5. How to use
(1) Use of seed dressing: Before sowing wheat, corn, cotton, soybeans, garlic, peanuts, potatoes and other crops, 6% tebuconazole suspended seed coating agent can be used for seed dressing according to a drug-to-seed ratio of 50-67 ml/100 kg of seeds. Wrapping the pesticide evenly on the surface of the seeds can effectively prevent the occurrence of various soil-borne diseases and prevent crop growth, with a lasting effect of up to 80 to 90 days.
(2) Spray use: In the early stages of the occurrence of diseases such as powdery mildew, scab, rust, etc., you can use 10 to 15 ml of 43% tebuconazole suspension mixed with 30 kg of water and spray evenly to quickly control the spread of the disease.
(3) Use of mixture: Tebuconazole has excellent miscibility and can be compounded according to different diseases. Common excellent recipes include: 45%% pentazole·prochloraz aqueous emulsion, used to prevent and treat anthrax, 30% Trichosporon·tebuconazole suspension is used to control rice blast and sheath blight, 40% benzyl·tebuconazole suspension, used to prevent and treat scab, 45% oxazolifen·tebuconazole suspension is used in many formulas to prevent and treat powdery mildew. It has good preventive, therapeutic and protective effects on the disease.
