Kuria Herbicide (Glufosinate Ammonium 13.5% SL)
The Premium "Burn-Down" Specialist for Tough Weeds in Cotton & Tea
Nichino Kuria is a powerful, non-selective contact herbicide designed to control weeds that other chemicals miss. Powered by Japanese technology, it uses a high-load surfactant system (over 58%) to penetrate waxy leaves and deliver rapid results.
Best For: Farmers dealing with Glyphosate-resistant weeds, Parthenium, and hard-to-kill grasses in Cotton and Tea plantations.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Action: Stops weed growth immediately. You will see the "burn-down" and drying effect within 3 to 5 days of spraying.
-
🛡️
Crop Safety (Contact Action): Unlike systemic herbicides, Kuria only kills the green parts it touches. It does not travel through the roots, making it safer for inter-row spraying in Cotton.
-
⏳
Resistance Breaker: Excellent against "super weeds" (like Eleusine and Parthenium) that have developed tolerance to Glyphosate.
-
🌧️
Superior Rainfastness: Thanks to its advanced sticking agents, it becomes rain-proof just 4 hours after application.
-
🌿
Soil Friendly: Bio-degradable and leaves no harmful residue in the soil, ensuring safety for your next crop rotation.

How It Works: Mode of Action
Kuria works differently from other weed killers. It is a "Contact Herbicide" that acts like a chemical scorch.
- Absorption: The high-quality surfactants allow the chemical to penetrate the weed's leaf surface instantly.
- Ammonia Trap: It blocks an enzyme called 'Glutamine Synthetase'. This causes toxic ammonia to build up inside the plant cells.
- Cell Burst: The excess ammonia destroys the plant's cell membranes and stops photosynthesis, causing the weed to turn yellow, dry up, and die.
Note: Since it is a contact killer, it will not travel to the roots. Complete coverage of the weed foliage is necessary for a total kill.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Barnyard grass (Echinochloa), Goosegrass, Broadleaf weeds, Parthenium. |
| Tea | Borreria (Buttonweed), Imperata (Thatch grass), Commelina, Ferns. |
| Non-Crop Areas | Cynodon (Bermuda grass), Cyperus rotundus (Nutsedge), General vegetation. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Kuria requires high water volume for proper coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 1000 - 1200 ml | 200 Litres | 5 - 6 ml | 96 |
| Tea | 1000 - 1200 ml | 200 Litres | 5 - 6 ml | 15 |
| Non-Crop | 1200 ml | 200 Litres | 6 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are young and actively growing (2 to 4 leaf stage). Do not spray on stressed or dry weeds.
- Mixing: Use clean water. Do not mix with muddy water or highly alkaline water (pH > 7.5) as it reduces effectiveness.
- Coverage: "Coverage is King." Since this is a contact herbicide, use a Flat Fan or Flood Jet nozzle to ensure the weeds are thoroughly wet.
- Safety: Always wear PPE (gloves, mask, goggles). Use a spray hood/shield in Cotton to prevent the chemical from touching the cotton crop.
Frequently Asked Questions
1. How is Kuria different from Glyphosate?
Glyphosate kills the roots (Systemic) but is slow. Kuria burns the green parts (Contact), acts much faster (3-5 days), and is safer for soil.
2. Will it kill the roots of the weeds?
No, Kuria is primarily a contact herbicide. It kills the top growth. For tough perennial weeds like Nutsedge (Motha), it will suppress growth but tubers may resprout.
3. Is it rainfast?
Yes, Kuria contains strong sticking agents. It becomes effective and rain-proof after 4 hours of application.
4. Can I use it on Parthenium (Carrot Grass)?
Yes! Kuria is highly effective against Parthenium and other weeds that have become resistant to other chemicals.
5. Is there an antidote for accidental poisoning?
No, there is no specific antidote (Atropine does NOT work). Treatment is symptomatic. Immediate medical attention and gastric lavage are critical.
