Product scienceHow 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.

How to applyDose & 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.
