Colorado - Bispyribac-Sodium 10% SC - FMC

FMC Colorado Bispyribac Sodium 10% SC Rice Herbicide

FMC Colorado is a selective, systemic, post-emergence herbicide containing Bispyribac Sodium 10% SC. FMC's current India product information lists Colorado for direct-seeded rice, transplanted rice and rice nurseries, with control of specified grass, sedge and broad-leaf weeds.

This page is limited to the crop, formulation and weed spectrum supported by current manufacturer information. It does not extend Colorado to non-rice crops or replace the directions, restrictions and precautions printed on the supplied pack.

Key Product Information

• Post-emergence rice herbicide: intended for use after listed weeds emerge in rice.
• Systemic activity: absorbed by susceptible weeds and moved to growing points.
• Broad weed spectrum: FMC lists important grasses, sedges and broad-leaf weeds in rice.
• Rice systems: manufacturer information covers direct-seeded, transplanted and nursery rice.
• Label-first application: rate, timing, water volume, field condition, re-entry and harvest interval must follow the current physical label.

Technical Specifications

How It Works

Bispyribac Sodium is classified as an HRAC/WSSA Group 2 herbicide. It inhibits the ALS/AHAS enzyme in susceptible weeds, interrupting production of essential branched-chain amino acids. Growth stops after uptake, followed by decline of susceptible weeds. The classification describes the site of action; it does not guarantee control where resistance is present.

Verified Rice Systems & Weed Spectrum

Use only where the current Colorado label lists the rice system and target weeds relevant to the field. Do not use this page to infer approval for another crop or unlisted weed.

Dose & Application

Read the current physical Colorado label before measuring or spraying. This page does not publish a universal per-acre, per-litre, pump or tank dose. Follow the supplied label for formulation rate, spray-water volume, weed stage, rice stage, field-water condition, weather limits, re-entry, harvest interval and maximum application count.

• Identify the rice cultivation system and weeds before treatment.
• Apply only at the label-listed crop and weed stages.
• Use calibrated equipment and obtain uniform coverage without drift to nearby crops.
• Wear all personal protective equipment specified on the label.
• Do not mix Colorado with another herbicide, pesticide, fertiliser or adjuvant unless every applicable current label expressly permits it.
• Recommendation cards are standalone shopping alternatives, not a tank-mix or compulsory spray sequence.
