The fungicide Tebuconazole is a little-known but effective drug that is designed to combat various fungal diseases of grain, garden, vegetable and many other crops. Tebuconazole has a protective, eradicating and therapeutic effect. The drug occupies one of the first places among the disinfectants.
Scope and form of release
Fungicide disinfect grains of wheat, barley, oats and rye. Grapes, onions, tomatoes, potatoes, beans, coffee and tea are also processed. Tebuconazole inhibits the development of a variety of fungal infections:
- helminthosporium root rot;
- grain mold;
- dusty, stony, hard, covered and stem smut;
- root rot;
- various spots;
- scab;
- Alternaria;
- powdery mildew;
- leaf rust;
- fusarium snow mold.
The drug is produced in the form of a whitish suspension concentrate, which is poured into plastic canisters with a volume of 5 liters.
Mechanism of action
The active substance of the drug is tebuconazole, the concentration of which is 6% or 60 g of the substance per liter of suspension. Due to its high mobility, the fungicide quickly moves to the place of accumulation of parasitic fungi, eradicates the infection and provides long-term protection to crops.
The active component of the drug destroys pathogens both on the surface and inside the grain. The substance penetrates into the seed germ, protects the seedlings and roots of the plant from damage by soil fungi. The drug is able to move to growth points. As soon as the fungicide solution gets on the seeds, tebuconazole inhibits the vital processes of fungi – it disrupts the biosynthesis of ergosterol in cell membranes, as a result of which they die.
The main part of the substance passes into the plant within 2-3 weeks after sowing. The fungicidal effect of the drug is manifested on the second day after the grain enters the soil.
Advantages and disadvantages
Fungicide Tebuconazole combines a number of positive qualities:
- it is used both for spraying cultivated plants and for disinfecting grains;
- wide range of action;
- helps both prevent the disease and suppress the development of an already existing pathogenic fungus;
- highly effective against smut diseases and root rot;
- has economical consumption;
- Excellent value for money and quality;
- the substance is distributed throughout the plant and destroys the fungus in all its parts;
- provides long-term protection.
In the drug Tebuconazole, agronomists identify one significant drawback. Under adverse climatic conditions (drought, waterlogging), the fungicide exhibits a pronounced retardant effect. (slows down emergence of shoots and growth of cereal crops).
Instructions for use
It is recommended to spray plants with Tebuconazole fungicide in calm weather, in the morning or in the evening. Before carrying out work, the spray gun is thoroughly washed from contamination. The suspension is shaken, the required amount of concentrate is poured and diluted in 2-3 liters of warm water. The resulting fungicide solution is mixed with a wooden stick and poured into the spray tank, which must be filled with the remaining water.
In the process of dressing the seeds, the working fluid should be constantly stirred. Diluted tebuconazole concentrate is not subject to long-term storage. The working composition is recommended to be prepared immediately on the day of processing.
crops
Tebuconazole helps protect crops from root rot, helminthosporiasis, various smuts, red-brown spot, snow mold, rust and powdery mildew. Diseases affect both the aerial part and the root system of the plant. Spraying with a fungicide is carried out at the first signs of infection or when there is a possibility of infection. 250-375 g of tebuconazole is required per hectare of plantings. Multiplicity of treatments – 1.

Grain dressing is carried out 1-2 weeks before sowing. To do this, 0,4-0,5 liters of concentrate is kneaded in a bucket of warm water. For a ton of seeds, 10 liters of working solution will be needed. Before the procedure grains must be calibrated and cleaned. The treatment of unsorted seeds leads to the fact that most of the substance is adsorbed by dust, which significantly reduces economic efficiency.
Other cultures
In the form of a spray, Tebuconazole is used to kill various parasitic fungi in the following crops:
- Large fruits. The fungicide effectively prevents scab on apples and powdery mildew on grapes. It is used at the rate of 100g/ha.
- Vegetable crops. To save tomatoes and potatoes from alternariosis, the drug is used at the rate of 150-200 g per hectare of plantings.
- Beans. Protects beans and peanuts from leaf spot. 125-250 g of the substance is consumed per hectare of the site.
- The fungicide is effective against omphaliosa blotch and rust fungus on a coffee tree. 125-250 g of the substance is used per hectare of plantings.
Processing of plants is carried out once. If necessary, repeat the procedure.
Analogues and compatibility with other drugs
Tebuconazole is compatible with many insecticides and fungicides used in seed and crop treatments. The fungicide is most effective in tank mixtures. But before mixing substances, drugs need to be checked for compatibility.
Tebuconazole can be replaced by analogues: Stinger, Agrosil, Tebuzan, Folicur, Colosal. All funds have the same active ingredient.
Safety regulations
Tebuconazole belong to the 2nd class of danger. The drug is harmful to humans and moderately toxic to fish and bees. It is not recommended to carry out work near water bodies and apiaries.
When working with the drug Tebuconazole should adhere to the following rules:
- wear tight gloves, protective clothing, goggles and a respirator;
- prepare a solution outdoors only;

- If swallowed, drink 2-3 glasses of water and seek medical advice.
The fungicide can be stored for no more than 2 years. Do not use expired product.

Conclusion
The use of seed treaters has a positive effect on productivity and provides effective protection to the plant. Subject to the instructions, terms and norms of application, the agrochemical Tebuconazole will not cause harm.
