Rulout Herbicide (Glyphosate 41% SL) by Nichino
The Ultimate Systemic Weed Killer for Tea Plantations and Non-Cropped Areas.
Rulout is a premium non-selective herbicide formulated by Nichino India. Designed with Japanese technology, it contains Glyphosate 41% SL, a powerful active ingredient that eliminates tough, deep-rooted weeds. Unlike ordinary weed killers that only burn the leaves, Rulout travels deep into the plant's system to destroy the roots, preventing regrowth and ensuring long-term field hygiene.
Best For: Tea estates, industrial sites, railway tracks, and managing difficult perennial grasses like Cogon grass and Bermuda grass.
Why Choose This Product? Key Benefits
- ⏱️Complete Root Kill: Uses advanced systemic action to travel from leaves to roots, killing rhizomes and tubers to stop weeds from coming back.
- ?️Japanese Quality Assurance: Manufactured by Nichino India (subsidiary of Nihon Nohyaku Co., Ltd.), ensuring superior surfactant quality and consistent performance.
- ⏳Long-Lasting Control: Effectively controls perennial weeds like Imperata cylindrica (Thatch grass) that are difficult to remove manually.
- ?️Superior Rainfastness: Formulated with high-quality surfactants that allow rapid absorption, becoming rainfast within 1 to 4 hours.
- ?Soil Safe: The chemical becomes inactive upon contact with soil, meaning it leaves no harmful residue for future crops.

How It Works: Mode of Action
Rulout works by "tricking" the plant's enzymes. It is a systemic herbicide, meaning it moves inside the plant's sap stream.
- Absorption: The liquid is sprayed on the green foliage. Special surfactants help the droplet spread and penetrate the waxy leaf surface.
- Translocation: Once inside, the active ingredient moves via the phloem (sugar transport channels) down to the roots and rhizomes.
- Inhibition: It blocks the EPSPS enzyme, which creates essential amino acids. Without these proteins, the plant starves and dies completely within 7 to 21 days.
Note: This is a slow-kill process. Visible yellowing starts in 7 days, and complete death occurs in about 3 weeks.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tea Plantations | Imperata cylindrica (Thatch grass), Cynodon dactylon (Bermuda grass), Broadleaf weeds, Climbers |
| Non-Cropped Areas | Sorghum halepense (Johnson grass), Parthenium, General vegetation control on bunds/industrial sites |
| Aquatic Weeds (Restricted) | Do not apply directly to water bodies; toxic to aquatic life. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less will result in weed regrowth; using too much wastes money.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | 800 - 1200 ml | 180 - 200 L | 5 - 7 ml | As per Label |
| Non-Cropped Area | 800 - 1200 ml | 200 L | 5 - 7 ml | - |
| Knapsack Spraying | - | - | 100 - 150 ml per 15L Tank | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always check the physical bottle label for the most current statutory PHI.
How to Apply: Best Practices
- Timing: Apply when weeds are actively growing and green. Avoid spraying during drought or on dust-covered weeds.
- Mixing: Use clean water. For hard water, adding Ammonium Sulfate (1-2%) can boost effectiveness.
- Coverage: In Tea gardens, use a Hooded Sprayer or shield to protect the tea bushes from drift. Use Flat Fan or FloodJet nozzles for coarse droplets (reduce drift).
- Safety: Always wear PPE (gloves, mask, goggles, boots). Wash hands thoroughly after use. Do not walk barefoot in treated areas.
Frequently Asked Questions
1. Can I use Rulout on Cotton or Vegetables?
No. Rulout is strictly registered for Tea and Non-Cropped areas. Using it over-the-top on cotton or vegetables will kill the crop unless it is an illegal HT variety.
2. How soon will the weeds die?
Glyphosate is a slow killer. You will see yellowing after 7 days, and complete death takes 14 to 21 days. Be patient—it is killing the roots.
3. What if it rains after spraying?
Rulout is generally rainfast within 1 to 4 hours. If it rains immediately after spraying (within 1 hour), effectiveness may drop, and re-application might be needed.
4. Who can spray this product?
According to Government of India regulations, Glyphosate should ideally be applied by Pest Control Operators (PCOs) to ensure safety and correct usage.
5. Does it leave residue in the soil?
No. Rulout binds tightly to soil particles and becomes inactive immediately, so it does not harm future crops planted in that soil.
