Tebuconazole Treats Rice With Empty Grains – Effective Solution For Quality Crops

Tebuconazole Treats Rice With Empty Grains

In rice cultivation, grain smut is one of the most serious problems, especially during the flowering and grain-forming stages. This disease not only increases the rate of grain smut but also reduces the quality of rice, greatly affecting the post-harvest price. Among the many active ingredients used for prevention and treatment, Tebuconazole is the best active ingredient for treating rice with grain smut because of its deep absorption ability and effective fungicidal effect. So what is special about this active ingredient and how to use it properly? Sataka will answer the above questions of farmers in the following article.

1. Understanding Rice Grain Deficiency Disease

1.1. What is Rice Grain Deficiency Disease?

Rice grain deficiency is a phenomenon in which rice cannot form solid grains. On the rice panicle, many grains are dark brown, even empty white, with empty, light or completely damaged grains. This is not a single disease but a combined consequence due to:

• Fungal infection: Mainly Fusarium spp. (causing red rot), Helminthosporium spp. (causing black grains), and some other harmful fungi.
• Wet weather during the rice flowering or post-flowering stage: heavy rain, prolonged night dew, poorly ventilated fields...
• Weakening of rice plant physiology due to lack of nutrients, pests and diseases that destroy the leaves and roots before.

1.2. Harmful Effects of Grain Smut

Grain smut is the main cause of serious losses in rice yield and quality. When infected, the rate of empty grains increases, many grains are not firm, and do not meet commercial standards. This not only reduces yield by 20-50%, but also greatly affects the selling price after harvest. Smut rice grains often change color, lose their shine, and break easily during the milling process, leading to low quality rice, making it difficult to sell in the export market. In addition, if not prevented and treated promptly, the disease can spread rapidly in conditions of heavy rain and high humidity, affecting the entire field in a short time.

2. What is the active ingredient Tebuconazole?

Tebuconazole is a fungicide of the Triazole group, widely used in agriculture worldwide. It is particularly effective in controlling diseases caused by endophytic fungi, which exist deep inside plant tissues.

Outstanding features:

• Selective mechanism of action: Tebuconazole inhibits the biosynthesis of ergosterol, an important component of the fungal cell membrane. When the membrane is broken, the fungus stops growing and dies.
• Strong internal absorption ability: The active ingredient penetrates the leaf epidermis and spreads quickly to all parts of the plant, including cotton and seeds.
• Long-lasting effect: Helps protect plants for many days after spraying, reducing the risk of re-infection.

The highlight of Tebuconazole compared to other active ingredients is its ability to treat from the inside, suitable for diseases that are difficult to control with external contact drugs.

3. Why is Tebuconazole Effective in Treating Grain Blot?

The systemic properties and broad-spectrum fungicidal properties make Tebuconazole a key "weapon" in preventing and treating grain bloat, especially in the current erratic weather conditions. Below are the mechanisms of action of Tebuconazole that are highly effective in treating grain bloat:

• Deep penetration into plant tissue: Not only on the surface, Tebuconazole enters the vascular system, helping to destroy fungi that have adhered to the rice panicle or on the grain.
• Prevent the spread of pathogens: If sprayed at flowering time, Tebuconazole helps to destroy pathogens early, preventing the fungus from developing.
• Increase the plant's resistance: When combined with nutritional preparations, the rice plant recovers quickly, the plant is strong, the panicle is strong, and the rate of natural bloat is reduced.

This is especially important in areas where rice is sown densely, where fields are frequently wet, or where rice varieties susceptible to fungal diseases are used.

4. How to Use Tebuconazole to Treat Rice with Rice Foliar Disease

Using the right time and dosage will help optimize efficiency and save costs. Here are detailed instructions:

4.1. Ideal spraying time:

• 1st time: When the rice is in bloom (about 5–10% of the flowers have bloomed). This is the time when the flowers are newly emerged and most susceptible to fungus.
• 2nd time: After flowering, about 5–7 days, to increase effectiveness and prevent the risk of re-infection.

Spraying exactly twice during the flowering stage will reduce the risk of grain foliar disease by 70–90%.

4.2. Recommended dosage:

• SC/EW form: 15–30ml/25 liters of water
• WP form: 25–50g/25 liters of water
• Can be increased or decreased depending on weather conditions, disease density and recommendations on the packaging

The above recommended dosage is for reference only. You should contact the store selling the product for detailed advice on how to use and the correct dosage or contact agricultural technical experts for appropriate advice.

4.3. Effective spraying method:

• Use a fine spray nozzle, spray evenly on the cotton surface
• Spray in the early morning or cool afternoon, avoid strong sunlight and showers
• Do not mix with herbicides or strong alkaline drugs

4.4 Combine with micronutrients:

• Add Boron, Zn, Ca, Si to help the rice flower to be strong and healthy, prevent physiological flatness
• Can be sprayed in combination or alternately to achieve comprehensive effectiveness

Supplement Boron, Zn, Ca for rice plants

5. Answers to Frequently Asked Questions (FAQ)

Should Tebuconazole be sprayed when the rice has fully emerged?

→ Yes. The emergence time is the key stage to prevent fungi from attacking the inside of the rice grain. It is recommended to combine an additional spray after emergence to maintain the effect longer.

Will Tebuconazole be washed away if it rains?

→ Thanks to its ability to penetrate quickly, if it rains 2-3 hours after spraying, the effect will remain the same. However, it is best to spray when the weather is stable.

Is Tebuconazole safe for natural enemies?

→ Yes. This is a selective active ingredient, has little effect on bees, spiders, and weaver ants, and does not disrupt the field ecosystem.

Can it be used for other crops?

→ Yes. In addition to rice, Tebuconazole is also used for mango, grapefruit, orange, pepper, coffee, etc. to prevent and treat many types of pathogenic fungi.
