Adaphon (Ethephon 39% SL): The Ultimate Plant Growth Regulator for Faster Ripening & Yield
Accelerate crop maturity, reduce harvest labor, and boost your farm's profitability with ADAMA's premium ethylene-releasing solution.
Adaphon is a highly effective plant growth regulator (PGR) that helps farmers take full control of their harvest timeline. By safely mimicking the plant's natural ripening hormone (ethylene), it ensures uniform fruit color, breaks alternate bearing cycles, and acts as a powerful defoliant for mechanized harvesting.
Best for: Mango, Tomato, Cotton, Pomegranate, Coffee, and Chilli.
Why Choose This Product? Key Benefits
- ⏱️Faster, Uniform Ripening: Speeds up color development and maturity in fruits like mangoes, chillies, and tomatoes for top market value.
- 🛡️Breaks Alternate Bearing: Helps orchard trees like mangoes produce consistent, reliable yields year after year instead of skipping seasons.
- ⏳Saves Huge Labor Costs: Synchronizes crop maturity so you can harvest everything in a single pass, drastically reducing manual picking time.
- 🌧️Superior Canopy Management: Acts as an excellent defoliant for cotton and pomegranate, improving air circulation and preparing crops for easy harvest.
- 🌿Cost-Effective Alternative: Delivers the exact same powerful results as leading originator brands (like Ethrel) but at a fraction of the cost.

How It Works: Mode of Action
Adaphon works from the inside out to naturally speed up your crop's biological clock:
- Systemic Absorption: The liquid quickly penetrates the plant's leaves and travels seamlessly through its vascular system.
- Ethylene Release: Once inside the plant's cells, the ethephon molecule breaks down and releases a powerful burst of ethylene gas.
- Growth Alteration: This hormonal boost triggers immediate physical changes—forcing fruits to sweeten and change color, causing older leaves to drop cleanly, or stimulating new flowers to bloom.
Target Crops & Pests
| Crop | Target Pest(s) / Purpose |
|---|---|
| Mango & Pomegranate | Flower induction, defoliation, and breaking alternate bearing cycles. |
| Cotton | Pre-harvest defoliation and accelerated boll opening for cleaner picking. |
| Tomato, Chilli & Coffee | Pre-harvest and post-harvest uniform ripening and color enhancement. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Mango | 100 - 150 ml | 200 L | 0.5 - 2.6 ml | Varies (Pre-bloom) |
| Cotton | 400 - 800 ml | 150 - 200 L | 2.0 - 4.0 ml | 10 - 14 Days |
| Tomato | 650 - 1000 ml | 150 - 200 L | 4.5 - 6.5 ml | 7 - 10 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Only apply at the exact correct growth stage. For example, spray cotton when 60-65% of the bolls are already open, or coffee when 10-15% of berries are red.
- Mixing: Never mix Adaphon with alkaline (hard) water. High pH water will destroy the chemical before it even touches your plants.
- Coverage: Spray evenly across the entire plant canopy. Avoid excessive soaking that causes the liquid to run off onto the soil.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. The raw concentrate is highly acidic and can cause severe skin burns.
Frequently Asked Questions
1. Is Adaphon the exact same as Ethrel?
Yes. Both products use the exact same active ingredient (Ethephon 39% SL). Adaphon simply offers a much more cost-effective option for farmers without sacrificing quality.
2. Can I use Adaphon to ripen fruits after I pick them?
Yes, Adaphon is widely used as a post-harvest dip for fruits like mangoes and tomatoes to ensure they turn a uniform, beautiful color before reaching the market.
3. Is it safe to spray while bees are pollinating my crops?
Yes. Ethephon is practically non-toxic to honeybees, making it very safe to use in orchards and fields during active pollination.
4. What happens if I spray too much?
Applying more than the recommended dose can severely burn the leaves, cause flowers to drop unintentionally, and damage the overall health of your crop. Always stick to the exact dosage.
5. Can I apply it near lakes or rivers?
No. While it is safe for birds and bees, it is toxic to aquatic life. Always keep a safe distance from water bodies to prevent chemical runoff.
