Rulout Herbicide (Glyphosate 41% SL): The Ultimate Weed Killer
Get complete control over stubborn weeds in Tea plantations and non-crop areas with Rulout by Nichino India.
Rulout is a premium non-selective systemic herbicide designed to solve your toughest weed problems. Unlike standard weed killers that burn only the leaves, Rulout absorbs into the plant and travels deep into the roots. It effectively destroys aggressive perennial weeds like Cogon grass and Bermuda grass, ensuring they do not grow back.
Best for: Tea Estates, Industrial Sites, Bunds, and Non-Cropped Areas.

How It Works: Mode of Action
Rulout uses a "Trojan Horse" strategy to kill weeds from the inside out.
[Image of systemic herbicide translocation in plants]- Absorption: The liquid is sprayed on the green leaves. Special surfactants help it penetrate the waxy surface immediately.
- Translocation: Once inside, the chemical travels through the plant's food transport system (phloem) down to the roots and rhizomes.
- Complete Kill: It blocks a specific enzyme (EPSPS) needed for growth. The plant starves, turns yellow, and dies completely within 7 to 20 days.
Note: Visible symptoms like yellowing take 4-7 days to appear. Patience is key!

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) |
|---|---|---|---|---|
| Tea Plantations | 800 - 1200 ml | 180 - 200 L | 6 - 10 ml | Refer to Label |
| Non-Cropped Area | 800 - 1200 ml | 200 L | 8 - 12 ml | - |
| Hard-to-kill Weeds | 1200 ml + AMS | 200 L | 10 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 actively growing (green and healthy). Avoid spraying during drought or when weeds are covered in dust.
- Mixing: Use clean water. If you have hard water, add Ammonium Sulfate (AMS) to improve results.
- Coverage: Use a "Hooded" or "Shielded" nozzle to ensure the spray hits the weeds but DOES NOT drift onto your Tea bushes.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not apply near water bodies.
Frequently Asked Questions
1. How long does Rulout take to kill weeds?
It is a slow-kill herbicide. You will see yellowing in 4-7 days, but complete death (root kill) takes about 15-20 days.
2. Can I use Rulout on Cotton or Vegetables?
No. Rulout is legally registered only for Tea and Non-Cropped areas. Spraying it over other crops will kill them.
3. What if it rains after spraying?
Rulout is rainfast within 1 to 4 hours. If it rains immediately after spraying (less than 1 hour), you may need to respray.
4. Does it damage the soil?
No. Glyphosate binds tightly to soil particles and becomes inactive, so it does not affect future crops planted in that soil.
5. Who can apply this product?
Per government rules, Glyphosate should be applied by Pest Control Operators (PCOs) or trained personnel to ensure safety.
