UPL Strider Herbicide:
Advanced Post-Emergence Weed Control for Paddy
UPL Strider is a selective post-emergence herbicide powered by Bispyribac Sodium 10% SC, specially designed for effective weed management in rice cultivation. It works by inhibiting the ALS (Acetolactate Synthase) enzyme, which is essential for amino acid synthesis in weeds. Once absorbed through the leaves and roots, the herbicide stops weed growth and gradually eliminates them, ensuring that rice plants receive maximum nutrients, sunlight, and space for healthy development.
Strider is widely trusted by paddy farmers because it controls grasses, sedges, and broadleaf weeds in both nursery and main field conditions. Its systemic activity allows the herbicide to move inside the weed plant tissues, providing consistent and long-lasting control during critical crop growth stages.

Strider Herbicide Features and Benefits
Broad Spectrum Weed Control
Effectively controls major grassy weeds, sedges, and broadleaf weeds commonly found in rice fields.
Systemic Action
Absorbed by weed foliage and roots and moves throughout the plant tissue to stop growth completely.
Flexible Application Window
Can be applied during the 2–5 leaf stage of weeds, providing farmers with a wider spraying window.
Crop Safety
Highly selective to rice crop when used at the recommended dose, ensuring strong crop growth.
Reduces Labor Cost
Helps reduce manual weeding operations, saving labor and increasing farm efficiency.
Long Lasting Field Cleanliness
Maintains weed-free fields during critical crop growth stages for better yield potential.
Mode of Action
Bispyribac Sodium belongs to the Pyrimidinyl Carboxy herbicide group and works by blocking the Acetolactate Synthase (ALS) enzyme, which is responsible for producing essential amino acids required for weed growth.
When the enzyme activity is disrupted, weeds stop growing within a few days and gradually die, allowing the rice crop to grow without competition for nutrients and sunlight.
Usage and Crop Recommendations
| Crop | Target Weeds | Dosage/ha | Dilution in Water (L/ha) | Waiting Period |
|---|---|---|---|---|
| Rice (Nursery) | Echinochloa crusgalli, Cyperus difformis, Ludwigia parviflora | 200 ml | 300 L | Not Required |
| Rice (Transplanted) | Echinochloa colona, Cyperus iria, Monochoria vaginalis | 200–250 ml | 300 L | ~78 Days |
| Rice (Direct Seeded) | Fimbristylis miliacea, Eclipta alba | 200–250 ml | 300 L | ~78 Days |
Application Guidelines
Application Method: Foliar spray using knapsack or power sprayer with flat-fan nozzle.
Best Time of Application:
15–25 days after transplanting when weeds are in 2–4 leaf stage.
Field Preparation:
Drain excess water before spraying and re-irrigate after 1–2 days for best weed control.
Rain Fastness:
Rainfall occurring several hours after application usually does not affect performance.
Safety and Handling
• Always read the manufacturer label before use.
• Use protective gloves, mask, and clothing during spraying.
• Do not overdose or mix with incompatible chemicals.
• Store in a cool, dry place away from sunlight and children.
