Details Functions How to use Characteristics package

Product details

Active ingredient content: Common dosage forms include 0.004% aqueous solution (i.e., 0.04 g of active ingredient per liter) and 0.01% soluble concentrate. This very low concentration reflects its extremely high biological activity.
Dosage forms: The most common are soluble concentrates (SL) and aqueous solutions (AS), but emulsifiable concentrates (EC) and soluble powders (SP) are also available.
Appearance: Typically a colorless to pale yellow, transparent liquid.
Product Characteristics: Easily soluble in polar solvents such as water and ethanol, and relatively stable, but susceptible to decomposition in the presence of strong bases.

Applicable Crops: Suitable for nearly all crops, including but not limited to:
--Field Crops: Rice, wheat, corn, cotton (growth promotion, yield increase)
--Vegetables: Tomatoes, cucumbers, peppers, watermelons, strawberries (flower and fruit preservation, and enlargement)
--Fruit Trees: Citrus, apples, grapes, pears, lychees (quality improvement, yield increase)
--Cash Crops: Tea, tobacco, peanuts, soybeans (improvement of resistance, quality improvement)

Functions

28-Epihomobrassinolide is an analog of natural brassinolide. It has extremely high physiological activity and comprehensive functions. Its main effects can be summarized as follows:
1. Promotes growth, increases yield and improves quality:
--Promotes cell division and elongation: Directly promotes cell division and expansion in plant vegetative organs (roots, stems, and leaves) and reproductive organs (fruits and seeds), thereby promoting root development, plant health, and fruit enlargement.
--Increases fruit set and reduces flower and fruit drop: Regulates nutrient flow within the plant, transporting nutrients to "sink" organs such as flowers and fruits, significantly improving fruit set.
-- Improved quality: Promotes the synthesis and accumulation of proteins, sugars, vitamins, and other substances, resulting in brighter fruit color, more uniform shape, and better taste, thereby increasing commercial value.

2. Enhanced stress tolerance:
- Alleviation of pesticide and fertilizer damage: Significantly alleviates and restores damage caused by improper use of herbicides, fungicides, and insecticides, or excessive fertilizer use, encouraging the plant to quickly grow new, robust tissue.
- Stress resistance: Significantly improves the crop's resistance and resilience to adverse environmental conditions, such as drought, flooding, low temperatures (freezing damage), high temperatures, and saline-alkali environments.
- Disease mitigation: By enhancing the plant's own immunity, it has a certain effect on mitigating and preventing certain diseases (such as viral diseases and powdery mildew).

3. Regulating photosynthesis and nutrient distribution:
- Enhanced photosynthetic efficiency: Increases chlorophyll content, prolongs the lifespan of functional leaves, and produces more nutrients. --Optimize nutrient distribution: guide the transportation of photosynthetic products to where they are needed (such as fruits, roots, and tubers), avoid wasting nutrients on ineffective growth, and thus increase economic yield.

4. Synergistic Effects with Fertilizers and Pesticides:
-- When mixed with foliar fertilizers (such as potassium dihydrogen phosphate), it can improve nutrient absorption efficiency.
-- When mixed with most insecticides and fungicides, it not only mitigates the risk of pesticide damage but also enhances efficacy, creating a synergistic effect.

How to use

Dosage and Dilution Method (using the most common 0.004% aqueous solution as an example): .

Dilution Ratio: Typically 2000-4000 times for foliar spraying

Calculation Method: Take 5-10 ml of 0.004% aqueous solution, add 15-30 kg of water (the amount in a conventional sprayer bucket), and mix well. Dosage: The typical dosage per acre is 5-10 ml.

Use Frequency: 2-3 applications throughout the entire growing season, with a single application during critical periods, spaced 7-10 days apart.

Important: The "double dilution method" must be used: First, thoroughly dissolve the product in a small amount of water in a cup, then pour it into a sprayer filled with water and stir thoroughly to ensure a uniform solution and avoid localized concentrations.

Use Period and Purpose

-Seedling Stage: Dilute and spray or dredge to promote root growth and ensure uniform and strong seedlings. - Pre-vegetative growth/vegetative period: Promotes stem and leaf growth, laying the foundation for high yields.
-Bud stage/pre-flowering: Promotes flower bud differentiation, conserving energy for flowering and fruiting.
-Flowering/young fruit stage: One of the most critical periods. Used to preserve flowers and fruits, prevent physiological fruit drop, and increase fruit set.
-Fruit expansion/grain filling: Another critical period**. Promotes cell expansion, directs nutrient transport to the fruit or seeds, and increases yield.
-Before and after adverse conditions: Preventive spraying before cold waves, droughts, heavy rains, and pesticide damage, or emergency spraying after they occur, can effectively mitigate losses and restore growth.
