Bispyribac Sodium 10% w/v SC

Bispyribac Sodium 10% SC

Bispyribac Sodium 10% SC is a next-generation, broad-spectrum post-emergent herbicide that solves one of the biggest challenges paddy farmers face every season — managing three completely different types of weeds (grasses, sedges, and broadleaf weeds) in a single, low-dose spray. CIB & RC approved in India and trusted across millions of acres of rice cultivation, it is one of the most effective and cost-efficient herbicide choices available to paddy farmers today.

How Bispyribac Sodium 10% SC Works

This herbicide works by inhibiting the ALS (Acetolactate Synthase) enzyme inside weed cells, which is responsible for producing the branched-chain amino acids valine, leucine, and isoleucine that weeds need for protein synthesis and growth. Once this enzyme is blocked, weed growth stops completely within 24 to 48 hours of application. The active ingredient is absorbed through both the foliage and roots of the weed and then translocated systemically throughout the entire plant, making it effective even against weeds that are partially submerged in water. Visible yellowing appears within 4 to 6 days, with complete weed kill achieved within 10 to 14 days, after which the field remains weed-free for 30 to 45 days.

Why Farmers Choose This Herbicide

One of the most valuable features of Bispyribac Sodium 10% SC is its 3-in-1 control — a single application handles grasses like Sanwa and Barnyard grass, sedges like Motha and Fimbristylis, and broadleaf weeds like Bhringraj and Caesulia all at once. This removes the need for multiple herbicide applications targeting different weed types, saving farmers both time and input cost per crop cycle.

This herbicide has excellent crop selectivity, meaning the rice plant breaks down the active ingredient extremely quickly in its own system while weeds remain fully affected — making it safe for all rice varieties including basmati, hybrid rice, and traditional varieties when used at the recommended dose and stage. It works equally well in transplanted rice, direct-seeded rice (DSR), and rice nurseries, giving it wide applicability across different paddy cultivation methods. Studies show that proper use of Bispyribac Sodium 10% SC can increase rice yield by 15 to 25% compared to unweeded fields, simply by removing weed competition during the most critical early growth stage.

Key Benefits

• Controls grasses, sedges, and broadleaf weeds in one spray
• Visible weed yellowing in 4 to 6 days, complete kill in 10 to 14 days
• Weed-free protection for 30 to 45 days from a single application
• Safe for basmati, hybrid, and all traditional rice varieties
• Works in transplanted rice, DSR, and rice nursery
• Can improve rice yield by 15 to 25% over unweeded fields
• Very low dose requirement — cost-effective for large paddy fields

Why Crop Nutrition Matters Alongside Weed Control

With weeds removed, the paddy crop gets full access to nutrients and water during its critical growth window. Supporting this with proper nutrition gives the best results. Products like Humic Acid 98% Flakes help strengthen root development and improve soil health, while Power PGR Liquid supports better tillering, flowering, and grain setting for higher final yield at harvest.

Safety Tips & Precautions

• Apply between 15 to 25 days after transplanting (DAT) or 15 to 20 days after sowing (DAS) for best results
• Drain water from the paddy field before spraying; refill within 2 to 3 days and maintain 3 to 4 cm standing water for at least 10 days
• Do not apply if the rice crop is under stress from drought, disease, or fertilizer burn
• Do not mix with sulphur, copper products, 2,4-D, or MCPA — spray separately with a 7-day gap
• Wear gloves, mask, and protective clothing while mixing and spraying
• Wash hands thoroughly after use; keep away from children and animals

Storage Instructions

Store Bispyribac Sodium 10% SC in a cool, dry place below 35°C away from direct sunlight and moisture. Keep tightly sealed in the original container and out of reach of children and animals.
