Higrow
Growth PromotersHigrow Ethephon 39% SL: The Ultimate Plant Growth Regulator
Unlock the full potential of your harvest with HPM Higrow, a premium plant growth regulator (PGR) designed to synchronize ripening and boost yields.
Modern agriculture requires more than just fertilizers; it requires precise control over crop lifecycles. Higrow (Ethephon 39% SL) acts as a powerful signal transducer, releasing ethylene gas directly into plant tissues. This naturally triggers essential growth stages like fruit ripening, flowering, and latex flow.
Best For: Farmers seeking uniform fruit color, synchronized harvest, and a safe, legal alternative to banned chemicals like Calcium Carbide.

8 topicsWhy farmers choose itWhy Choose This Product? Key Benefits
- ⏱️ Uniform Ripening: Ensures all fruits (like Mangoes and Tomatoes) ripen at the same time, preventing uneven harvests.
- ?️ Safe & Legal: The approved, non-carcinogenic alternative to Calcium Carbide for post-harvest treatment.
- ⏳ Labor Saver: Reduces the number of pickings in crops like Coffee by forcing synchronous berry ripening.
- ?️ Climate Smart: Induces flowering in Mango and Pineapple even during erratic weather conditions.
- ? Latex Booster: Increases latex flow duration in Rubber trees by preventing rapid clotting.
Product scienceTechnical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Higrow (HPM Chemicals) |
| Technical Name | Ethephon 39% SL |
| Mode of Action | Systemic Ethylene Release |
| Chemical Group | Organophosphonate |
| Formulation | Soluble Liquid (SL) |
| Toxicity Label | Moderately Toxic (Blue/Yellow Triangle) |
Product scienceHow It Works: Mode of Action
Higrow works by mimicking nature. It contains Ethephon, which remains stable in the bottle (acidic pH).
- Penetration: Once sprayed, the liquid is absorbed into the plant leaves or fruit peel.
- Activation: Inside the plant, the natural pH is higher (above 5.0). This change causes Higrow to break down.
- Release: It releases Ethylene gas ($C_2H_4$) directly into the cells. This signals the plant to ripen fruit, drop leaves, or start flowering immediately.
Useful detailsTarget Crops & Pests
| Crop | Benefit / Action |
|---|---|
| Mango | Induces flowering in "off" years & uniform post-harvest ripening. |
| Pineapple | Induces uniform flowering for a single-pass harvest. |
| Coffee | Uniform berry ripening to facilitate "fly picking". |
| Rubber | Increases yield by prolonging latex flow time. |

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can cause leaves to drop (defoliation).
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Application Type | Dose (ml / Litre) | Est. Water (L / Acre) | PHI (Days) |
|---|---|---|---|---|
| Mango | Flower Induction | 1.0 – 2.0 ml | 200 - 500 L | - |
| Pineapple | Flower Induction | 1.0 – 2.0 ml | 150 - 200 L | - |
| Tomato | Post-Harvest Dip | 1.0 ml | As Needed (Dip) | - |
| Coffee | Berry Ripening | 1.0 – 2.5 ml | 200 L | - |
| Rubber | Bark Brushing | 2.0 – 2.5 ml | Paste/Brush | - |
*Note: For Mango Post-Harvest Dip, use 1.0 ml per Litre of water. Never dip immature fruits.
Useful detailsHow to Apply: Best Practices
- Timing: For Mango flowering, apply starting mid-October or early November. For post-harvest ripening, apply only to mature green fruits.
- Mixing: Do NOT mix with alkaline products like Bordeaux mixture, as this neutralizes the effect instantly. Use plastic or stainless steel equipment (it is corrosive to mild steel).
- Coverage: Ensure uniform spray coverage for flowering induction. For post-harvest, a dip treatment is best for even color.
- Safety: Always wear PPE (gloves, mask, goggles). This product is acidic and can cause eye damage. Wash hands thoroughly after use.

Frequently Asked Questions
1. Is Higrow better than Calcium Carbide ("Masala")?
Yes. Calcium Carbide is banned and carcinogenic (cancer-causing). Higrow (Ethephon) is the government-approved, safe standard for fruit ripening when used correctly.
2. Can I use this if it is about to rain?
No. Higrow is highly soluble and will wash off. Avoid spraying if rain is expected within 4-6 hours. You can use a sticker/spreader to improve rain-fastness.
3. Why did my mangoes turn yellow but stay sour?
You likely applied Higrow to immature fruits. Ethephon triggers color change and softening, but if the fruit hasn't reached "maturity" (sugar development), the taste will remain poor. Only treat mature green fruits.
4. How often should I apply it to Rubber trees?
Do not exceed 4 applications per year (March, Aug, Sept, Nov). Overusing it can lead to "Tapping Panel Dryness" where the tree stops producing latex completely.
5. Can I mix Higrow with fungicides?
Generally, yes, provided the fungicide is not alkaline. However, always perform a small jar test first to ensure compatibility.
