Key Formulation Takeaway
With its high solubility, proven tank stability, and adaptable dose range, Ethephon 480g/L SL & 40% SL meet the diverse operational needs of growers, contractors, and distributors worldwide.
This makes it an ideal choice for anyone seeking reliable, uniform results in fruit ripening, cotton boll opening, or latex yield improvement.
Mode of Action
Ethephon functions as a maturation-promoting plant growth regulator through its unique mode of action:
Once applied, Ethephon is absorbed by plant tissues—including leaves, stems, fruits, and seeds—and moves systemically to the target sites within the plant.
Ethylene Release Mechanism
After absorption, Ethephon decomposes within plant cells under slightly alkaline conditions, releasing ethylene gas, which acts as an endogenous plant hormone.
This released ethylene is the same natural hormone that plants produce to regulate key growth and maturation processes.
How Ethylene Influences Plants
-
Fruit Ripening: Ethylene accelerates the ripening process by stimulating enzymes responsible for converting starches to sugars, softening fruit tissue, and enhancing color development.
-
Defoliation & Shedding: Ethylene weakens the bond between the stem and leaves or fruit, promoting uniform shedding. This is particularly useful for crops like cotton where boll opening and leaf drop aid mechanical harvesting.
-
Flower Induction & Sex Expression: In certain crops like pineapples, ethylene can be used to synchronize flowering or alter the ratio of male to female flowers, improving yield potential.
-
Dwarfing & Growth Regulation: Ethylene slows down cell elongation, helping manage plant height in cereals and ornamental crops to reduce lodging and improve light penetration.
-
Latex Yield Improvement: In rubber trees, ethylene enhances latex flow by stimulating the laticifer cells, resulting in higher output per tapping.
Systemic Movement
Once applied, the soluble liquid formulation ensures that Ethephon penetrates plant tissues efficiently.
Its systemic translocation ensures even ethylene distribution to the target sites, enabling consistent physiological responses even under variable field conditions.
Key Takeaway
By leveraging this predictable ethylene release, POMAIS Ethephon 480g/L SL & 40% SL helps growers manage ripening schedules, harvest timing, plant structure, and latex output more effectively—all within a single, easy-to-apply solution.

Field Use Scenarios
POMAIS Ethephon 480g/L SL & 40% SL is widely used across different regions and cropping systems for reliable growth regulation and harvest improvement.
Below are typical field scenarios that show how growers apply this product to maximize yield and quality.
Scenario 1: Cotton – Boll Opening & Defoliation
In major cotton-growing regions, growers apply Ethephon during late-season when the majority of bolls have matured.
By using 4500–6000 times dilution per hectare, farmers achieve uniform boll opening and natural leaf drop, which improves picking efficiency and fiber quality.
This practice is common in areas where mechanical harvesters are used, minimizing the need for multiple field passes.
Scenario 2: Bananas – Ripening Synchronization
Banana producers use Ethephon to induce even ripening before fruit enters post-harvest handling.
A typical dose of 50–70 mg/kg fruit is applied through airtight fumigation in ripening chambers.
This ensures bananas reach the market with consistent color and taste, especially important for export buyers who demand uniformity.
Scenario 3: Rubber Plantations – Latex Yield Boost
In rubber plantations, tappers apply a localized smear of Ethephon solution—0.12–0.16 ml per plant—on the bark near the tapping cut.
This stimulates laticifer cell activity, increasing latex flow without damaging the tree.
Such treatments are integrated into scheduled tapping cycles for sustainable productivity.
Scenario 4: Tomatoes – Uniform Color Development
Tomato growers apply Ethephon as a foliar spray at 12000–15000 times dilution per hectare when fruits reach mature green stage.
This encourages simultaneous ripening, reduces sorting losses, and aligns harvest timing with market demand—critical for fresh-market and processing supply chains.
Scenario 5: Pineapples – Flower Induction
In pineapple farms, Ethephon is used to synchronize flowering so that harvest dates can be better managed.
Field staff apply the product through crown or whorl application at specific developmental stages, ensuring more uniform fruit size and maturity.
Key Takeaway:
These field-proven scenarios demonstrate how POMAIS Ethephon 480g/L SL & 40% SL adapts to diverse crops and production goals,
helping growers achieve predictable results, improved labor efficiency, and higher returns.
