- Target: Controls weeds like grasses, sedges, and broadleaf species that infest rice fields.
- Mode of Action: It is an ALS inhibitor that stops the production of branched-chain amino acids (valine, leucine, isoleucine) needed for plant growth, leading to chlorosis and eventual death of weeds.
- Systemic and Selective: It moves through the plant's roots and foliage, targeting weeds without harming the rice crop.
- Post-emergence: Applied after weeds have germinated, typically at the 2-5 leaf stage.
- Formulation: A 10% Suspension Concentrate (SC) that is effective at low dosage rates.
Application Guidelines
- Preparation: Shake the bottle well before use.
- Timing: Apply when weeds are at the 2-5 leaf stage.
- Broad-Spectrum Control: Controls both annual and perennial broadleaf and grassy weeds by affecting their essential growth processes.
- Weather: Do not apply if rain is expected within 6 hours of application.
- Broad-Spectrum Control: Controls both annual and perennial broadleaf and grassy weeds by affecting their essential growth processes.
Important Considerations
- Crop Safety: Bispyribac sodium is specifically formulated to be safe for rice crops.
- Weed Spectrum: It is a broad-spectrum herbicide, effectively controlling various types of weeds.
- Absorption: It is absorbed quickly by weeds through the leaves and roots.
