Bayer Ethrel is a plant growth regulator that regulates growth in crops, such as mango, tomato, and other fruit crops. Bayer Ethrel plant growth regulator promotes the uniform ripening of the fruits and reduces crop loss. This plant growth regulator is quickly absorbed by the crops and provides immediate results within a few hours of application. The water-soluble liquid formulation of Ethrel plant growth regulator lasts for a longer period, reducing application frequency.
Key Features and Benefits of Bayer Ethrel:
Uniform Crops: Bayer Ethrel plant growth regulator penetrates deeply into the roots and releases plant hormones that ensure all crops mature at the same time.
Long-lasting: Bayer Ethrel plant growth regulator lasts for a longer period and reduces reapplication rates of the product.
Increases Crop Production: Bayer Ethrel plant growth regulator improves flowering and fruiting in the crops and promotes higher yield.
Regulates Crop Growth: Bayer Ethrel plant growth regulator regulates the growth process, enhancing fruit color, taste, and overall crop quality.
Bayer Ethrel Uses:
Bayer Ethrel plant growth regulator is recommended for selected fruit, vegetable, plantation, and commercial crops:
Fruit Crops: Mango, Pineapple, Pomegranate
Vegetable Crops: Tomato
Plantation Crops: Coffee, Rubber
Bayer Ethrel Dose Per Litre:
The concentration and application stage must be selected crop-wise because Ethrel Plant Growth Regulator can produce different responses at different rates. Use clean water, measure accurately, and never increase the concentration to obtain a faster response.
Crop | Application Method | Dose / Acre | Per 15L Pump | When to Apply |
|---|
Coffee | Foliar Spray | 200–500 ml | 7.5–37.5 ml | Berry ripening stage |
Mango | Foliar Spray | 200–500 ml | 15–30 ml | Mature fruit stage |
Tomato | Post-harvest Dip or Directed Spray | Not acre-based | 15 ml | Mature green stage |
Pineapple | Central Whorl Application | 154–205.2 ml | 3.75 ml | Flower induction stage |
Pomegranate | Foliar Spray | 200–500 ml | 15–30 ml | Before bahar treatment |
Rubber | Directed Tapping-Panel Application | Depends on tree count | Not applicable | Active tapping period |
How to Use Bayer Ethrel:
Shake the Bayer Ethrel bottle gently before measuring the soluble liquid formulation.
Calculate the required quantity according to the crop, purpose, and application stage.
Fill the spray tank halfway with clean water.
Add the measured Ethrel Plant Growth Regulator slowly while stirring the water.
Pour in the remaining water and mix until the solution is uniformly diluted.
Apply the prepared solution evenly to the required plant parts without excessive dripping.
For pineapple, direct the measured solution into the central whorl instead of spraying the entire canopy.
For rubber, use the recommended directed treatment on the tapping panel rather than a normal foliar spray.
Prepare only the quantity needed for immediate application and clean the equipment after use.
Best Time to Apply:
Application timing depends on the intended crop response. Use the product when the plant reaches the correct physiological stage, such as mature-green fruit for ripening, suitable vegetative maturity for pineapple flowering, or the planned pre-bahar period for pomegranate defoliation. Spray during calm morning or evening hours and avoid application before rainfall.
Frequency of Application and Re-entry Period:
Frequency of Application: Ethrel Plant Growth Regulator is generally used once for a particular crop objective. Repeated treatment should only be made when the crop recommendation specifically permits another application.
Re-Entry Period: Keep workers, children, and animals away from the treated area until the spray has dried. Protective clothing should be worn if early entry is necessary.
Compatibility: The formulation is acidic and should not be combined with lime, alkaline products, or unverified mixtures. Conduct a small jar test before mixing it with another agricultural input.
Safety, Precautions and Handling:
Wear gloves, protective eyewear, a mask, long clothing, and closed footwear while handling the product.
Avoid splashes on the skin and eyes while measuring Ethrel Plant Growth Regulator.
Do not eat, drink, smoke, or chew during preparation and application.
Never use a higher concentration to force quicker ripening or a stronger crop response.
Prevent spray drift from reaching neighbouring crops and untreated plants.
Wash exposed skin, contaminated clothing, measuring tools, and equipment after use.
Do not release leftover spray solution into wells, ponds, drains, canals, or irrigation water.
