Ethephon 39% SL is a widely used Plant Growth Regulator (PGR) in agriculture.
Technical Name: Ethephon (2-chloroethylphosphonic acid).
Formulation: 39% Soluble Liquid (SL), meaning it contains 39% active ingredient dissolved in a liquid carrier.
Mode of Action: Ethephon is a systemic PGR. When applied to a plant, it penetrates the tissues, is translocated, and slowly breaks down to release ethylene (a natural plant hormone). This released ethylene then regulates various physiological processes in the plant.
The specific effect of Ethephon 39% SL varies depending on the crop, the application timing, and the dosage.
| Crop | Primary Purpose | Specific Actions |
| Mango | Flower induction & Ripening | Induces profuse flowering; helps break alternate bearing tendencies; post-harvest treatment for uniform ripening. |
| Pineapple | Flower Induction & Ripening | Induces uniform flowering for synchronized harvesting; promotes even ripening. |
| Tomato | Ripening | Post-harvest dipping of mature green fruits to accelerate uniform ripening and improve coloration. |
| Coffee | Uniform Ripening | Accelerates and synchronizes the ripening of berries, especially Arabica and Robusta varieties. |
| Rubber | Latex Yield Stimulation | Applied to the tapping cut of the bark to increase the flow and yield of latex. |
| Pomegranate | Defoliation & Flowering | Promotes leaf shedding (defoliation) to encourage better flowering and fruit set. |
| Cotton | Boll Opening | Used to promote uniform opening of cotton bolls for easier harvest. |
The dosage and method are crucial and depend on the specific crop and desired effect. Always refer to the specific product label for the most accurate and safe instructions.
General Concentration: A common range for general application is about 1.0 to 2.5 ml per liter of water.
Application Methods:
Foliar Spray: Spraying on the leaves and fruit (for ripening, flower induction, defoliation).
Post-Harvest Dip: Dipping harvested fruits (like mango or tomato) in a diluted solution.
Trunk/Bark Application: Brushing the solution onto the tapping cut in rubber trees to stimulate latex flow.
