Land Rider Herbicide (Bispyribac Sodium 10% SC)
The "One-Shot" Post-Emergence Solution for Grasses, Sedges, and Broadleaf Weeds in Rice.
Land Rider by Nichino India is a technologically advanced, broad-spectrum herbicide designed to protect your paddy fields. It replaces labor-intensive manual weeding by effectively eliminating tough weeds like Echinochloa (Barnyard Grass) without harming your rice crop.
Formulated as a high-quality Suspension Concentrate (SC), it is safe for the applicator and highly effective on young, actively growing weeds.
Why Choose This Product? Key Benefits
-
⏱️
Immediate Growth Arrest: Weeds stop growing within hours of application, preventing them from competing with your crop for nutrients.
-
🛡️
High Crop Safety: Features "Metabolic Selectivity," meaning it kills weeds but is safely digested by the rice plant, leaving your crop healthy.
-
⏳
Systemic Root Kill: Absorbed by leaves and moves down to the roots (phloem mobility), ensuring weeds do not grow back.
-
🌧️
Rainfastness: Requires only 6 hours of rain-free weather after spraying for complete absorption.
-
🌿
Broad Spectrum Control: A single spray controls Grasses, Sedges, and Broadleaf weeds simultaneously.

How It Works: Mode of Action
Land Rider works by starving the weed of essential proteins required for survival.
- Uptake: It is absorbed through foliage and roots, translocating to the growing tips of the weed.
- Inhibition: It blocks the ALS enzyme, stopping the biosynthesis of essential amino acids (Valine, Leucine, Isoleucine).
- Result: Cell division stops immediately. The weed turns yellow (chlorosis), then brown (necrosis), and dies completely.
Note: Rice plants possess specific enzymes that degrade the chemical rapidly, ensuring the crop remains unharmed.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Nursery) | Barnyard Grass (Echinochloa crus-galli), Jungle Rice |
| Rice (Transplanted) | Sedges (Cyperus difformis, Cyperus iria) |
| Direct Seeded Rice | Broadleaf Weeds (Eclipta alba, Ludwigia parviflora) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Application must happen when weeds are at the 2-5 leaf stage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 80 - 100 ml | 120 - 200 L | 0.5 - 0.8 ml | 78 Days |
*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 and have 2 to 5 leaves (approx. 10-15 DAT or 15-25 DAS).
- Mixing: Use a Flat Fan or Flood Jet nozzle for uniform coverage. Avoid hollow cone nozzles.
- Coverage: **Critical Step:** Drain standing water from the field before spraying so weeds are exposed. Reflood the field 48-72 hours after spraying and maintain water depth for 5-7 days.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use in aquaculture (fish) ponds.
Frequently Asked Questions
1. Does Land Rider require clear weather?
Yes, it requires at least 6 hours of rain-free weather after spraying to be fully effective.
2. Can I spray when the field is flooded?
No. You must drain the water first. If weeds are submerged, the chemical cannot contact the leaves, and the application will fail.
3. Is this product safe for fish?
No, Bispyribac Sodium is toxic to fish. Do not allow runoff into fish ponds.
4. Will it kill mature weeds (older than 5 leaves)?
Efficacy drops significantly on hardened, mature weeds. Always target the 2-5 leaf stage for best results.
5. Can I control resistant Echinochloa with this?
Yes, Land Rider is an effective tool against Echinochloa, but ensure proper dosing (100ml/acre) and rotate with other herbicides to prevent resistance buildup.
