Shivalik Bispa Herbicide - Bispyribac Sodium 10% SC

Post-Emergence Systemic Herbicide for Broad-Spectrum Weed Control in Rice

Shivalik Bispa (Bispyribac Sodium 10% SC) is a selective, post-emergence systemic herbicide developed for effective weed management in all major rice cultivation systems, including direct-seeded rice, transplanted rice and rice nurseries. It provides excellent control of grasses, sedges and broadleaf weeds, allowing rice plants to grow without weed competition.

Its systemic action ensures rapid absorption through weed foliage and movement throughout the plant, stopping weed growth and eliminating weeds from the roots. Bispa helps improve nutrient availability, water utilization and crop productivity while supporting healthy rice establishment.

Product Specifications

Key Features & Benefits

• Broad-spectrum control of grasses, sedges and broadleaf weeds.
• Suitable for direct-seeded, transplanted and nursery rice.
• Post-emergence systemic herbicide with rapid absorption.
• Stops weed growth soon after application.
• Reduces crop competition for nutrients, moisture and sunlight.
• Improves crop establishment and overall yield potential.
• Provides effective control with a low application dose.

Mode of Action

Bispyribac Sodium is absorbed through weed leaves and translocated throughout the plant. It inhibits the Acetolactate Synthase (ALS) enzyme, preventing the production of essential amino acids required for weed growth. The weeds gradually stop growing, turn yellow and eventually die.

Recommended Crop

• Direct-Seeded Rice (DSR)
• Rice Nursery
• Transplanted Rice

Target Weeds
