0.1% Brassinolide Functional Effects and Usage
0.1% Brassinolide
Category: Plant growth regulators
CAS NO.:72962-43-7
Molecular formula:C29H50O6 / C28H48O6
Molecular weight：494.71 / 480.69
1. Product Details
Active Ingredient: 0.1% Brassinolide (commonly 24-epibrassinolide, 28-homobrassinolide, or 14-hydroxybrassinosteroid)
Formulation: Soluble Solution (SL), Emulsifiable Concentrate (EC), or Aqueous Solution (AS)
2. Functional Effects
Brassinolide is a highly effective, broad-spectrum plant growth regulator. Its core functions include:
1. Growth Promotion: Enhances cell division and elongation, accelerates stem and leaf growth, and shortens the reproductive cycle.
2. Enhances Stress Resistance: Alleviates stresses such as pesticide damage, frost damage, drought, and salinity, enhancing crop resilience.
3. Increases Yield and Quality:
4. Preserves flowers and fruits, reducing flower and fruit drop (e.g., Solanaceae and fruit trees);
5. Promotes fruit enlargement and uniform coloring (e.g., grapes and citrus);
6. Increases grain plumpness (e.g., rice and wheat). 7. Synergistic Effect: When mixed with insecticides, fungicides, and foliar fertilizers, it can enhance the efficacy of both pesticides and fertilizers.
3. Usage
Applicable Crops:
Cereal crops (rice, wheat), fruits and vegetables (tomatoes, cucumbers, strawberries, citrus), cash crops (cotton, rapeseed), etc.
Critical Periods:
- Seedling stage: Promotes root growth and seedling growth;
- Pre-flowering/flowering period: Preserves flowers and fruits;
- Young fruit stage: Promotes fruit enlargement;
- Before and after stress: Alleviates pesticide and frost damage.
Dilution Ratio:
A 0.1% formulation is generally diluted 2000-4000 times (e.g., 5ml to 10-20kg of water).
Recommended Dosage:
- Foliar spray: Use 5-10ml of formulation per acre, dilute with 30-50kg of water, and spray evenly.
- Spray 2-3 times during the growing season, with intervals of 7-10 days.
4. Precautions
Excessive use is strictly prohibited: High concentrations can inhibit growth and cause leaf curling and deformity.
Spraying time: Avoid midday temperatures (>30°C) and strong sunlight, and spray in the morning and evening when there is no wind.
Mixing taboos:
- Do not mix with strongly alkaline pesticides (Bordeaux mixture, lime sulfur);
- Test compatibility on a small scale before mixing.
Safety interval: Discontinue use 7-10 days before harvest.
