GALIGAN (ADAMA)

Galigan Herbicide (Oxyfluorfen 23.5% EC) – Powerful Weed Control
Eliminate stubborn broadleaf and grassy weeds with Galigan, a highly effective, dual-action herbicide designed for optimal crop protection and higher yields.
Weed competition can destroy up to 80% of your crop yield by stealing essential water, sunlight, and nutrients. Galigan (powered by Oxyfluorfen) acts as a powerful shield, offering both pre-emergence and early post-emergence control. It creates a chemical barrier on the soil surface to stop weeds before they sprout and burns down existing weeds on contact.
Say goodbye to aggressive weeds and protect your investment with ADAMA's trusted Galigan formulation.
Why Choose Galigan Herbicide? Key Benefits
- ⏱️Rapid Action: Fast-acting contact formula that quickly burns down visible weeds when exposed to sunlight.
- 🛡️Long-Lasting Soil Barrier: Forms a tight, protective layer on the soil surface that prevents new weed seeds from germinating for weeks.
- ⏳Application Flexibility: Can be used reliably as both a pre-emergence treatment (before weeds sprout) and a post-emergence spray.
- 🌧️Excellent Soil Retention: Binds strongly to the soil, meaning it won't easily wash away into deep groundwater during irrigation.
- 🌿Perfect for Specialty Crops: Specifically engineered to be safe for waxy crops like onions and garlic when applied at the correct growth stages.

How It Works: Mode of Action
Galigan destroys weeds using a sunlight-driven, three-step scientific process:
- Enzyme Blockade: It stops the plant from producing an essential enzyme called PPO, halting chlorophyll production.
- Sunlight Activation: Once exposed to sunlight, it creates highly destructive oxygen radicals inside the weed's cells.
- Rapid Cell Destruction: These oxygen radicals destroy the cell membranes, causing the weed to rapidly dry out, turn brown, and die.
When applied to bare soil, it forms a chemical blanket. When a sprouting seed touches this layer, the young shoot is instantly destroyed.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Onions (Transplanted & Seeded) | Broadleaf weeds (Chenopodium, Amaranthus) & Grasses (Echinochloa, Phalaris) |
| Tea Plantations | Tough grasses (Digitaria, Imperata) & Broadleaf varieties |
| Fruit Orchards & Forestry | Wide range of seasonal flushes and under-canopy weeds |
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) |
|---|---|---|---|---|
| Transplanted Onions | 170 - 340 ml | 160 - 300 L | ~ 1.5 ml | 40 - 90 |
| Direct Seeded Onions | 200 - 400 ml | 160 - 300 L | ~ 1.5 ml | 40 - 90 |
| Tea Plantations | 260 - 400 ml | 200 - 300 L | ~ 1.5 ml | 15 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For direct-seeded onions, ONLY apply at the 2-to-4 true leaf stage. For transplanted onions, apply strictly within 2 days of transplanting. Galigan requires sunlight to activate effectively.
- Mixing: Ensure the soil is finely prepared and weed-free before pre-emergence application. A light irrigation after pre-emergent spraying helps activate the barrier.
- Coverage: Because Galigan is a contact herbicide, uniform and complete spray coverage over the weeds is absolutely mandatory for post-emergent success.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not walk into the treated field for at least 24-48 hours.
Frequently Asked Questions
1. Can I use Galigan on Potato or Groundnut crops?
No. As of October 2023, the Indian Government has strictly banned the use of Oxyfluorfen on all potato and groundnut crops.
2. Does this herbicide need sunlight to work?
Yes! Galigan's weed-burning action is powered directly by sunlight. If applied on heavily overcast days, the results will be significantly slower.
3. When is it perfectly safe to spray on my direct-seeded onions?
You must wait until the onion plants have reached the "2 to 4 true leaf" stage. By this time, they have developed a protective waxy coating that keeps them safe from the chemical.
4. What happens if I disturb the soil after a pre-emergence spray?
Breaking or hoeing the soil surface will shatter the invisible chemical barrier Galigan creates, allowing new weed seeds beneath the barrier to sprout.
5. What should I do if the chemical touches my skin or eyes?
Immediately flush the exposed area with clean water for at least 15 to 20 minutes and seek medical attention. Never induce vomiting if accidentally swallowed.
