Active formulation and weed control mechanism
- Active ingredient: Bispyribac-sodium 10% SC (suspension concentrate formulation, HRAC Group 2).
- Mode of action: Inhibits the acetolactate synthase (ALS) enzyme, cutting off essential amino acids in susceptible grass and sedge weeds.
- Target weed spectrum: Controls barnyard grass (Echinochloa spp.), rice sedges (Cyperus spp.), and broadleaf weeds in direct-seeded and transplanted rice.
- Selectivity: Highly selective to rice plants, causing zero injury to the main crop when sprayed at recommended doses.
Pack sizes, price determinants, and dealer verification
- Pack sizes: Marketed in 50 ml (for small plots), 100 ml (standard 1-acre pack), 200 ml, 500 ml, and 1-litre commercial bottles.
- Price factors: Ex-retail prices depend on container size, regional distributor logistics, and local GST invoicing.
- Authenticity checks: Inspect tamper-evident holographic seals, manufacturer batch numbers, and expiry dates to avoid counterfeit goods.
- Licensed purchase: Always buy from state-licensed agrochemical retailers and demand a printed GST purchase receipt.
Application dosage calibration and spraying technique
- Dosage rate: Standard recommendation is 80 to 100 ml per acre diluted in 120 to 150 litres of clean water.
- Application window: Apply 15 to 25 days after sowing or transplanting when weeds have 2 to 4 leaves.
- Field water management: Drain standing water prior to spraying, and re-flood the field 48 hours post-application to suppress weed seeds.
- Nozzle selection: Use flat fan or floodjet nozzles for uniform herbicide spray distribution.
