Officer Herbicide (Bispyribac Sodium 20% + Pyrazosulfuron Ethyl 15% WDG)

The "One-Shot" Broad-Spectrum Weed Solution for Healthy Rice Fields

Officer Herbicide is a technologically advanced, dual-action weed killer designed specifically for modern rice farming. By combining two powerful active ingredients—Bispyribac Sodium and Pyrazosulfuron Ethyl—in a high-quality granule formulation, it eliminates the need for multiple sprays. It effectively controls grasses, stubborn sedges, and broadleaf weeds simultaneously, ensuring your crop gets all the nutrition it needs without competition.

Best For: Transplanted Rice (TPR), Wet Direct-Seeded Rice (DSR), and Nurseries.

Why Choose This Product? Key Benefits

• ⏱️
  Perfect Timing (Early Post-Emergent): Designed to hit weeds at the critical "1-3 leaf stage," stopping them before they steal nutrients from your crop.
• 🛡️
  Complete Spectrum Control: Offers cross-spectrum protection by killing Grasses (Echinochloa), Sedges (Cyperus), and Broadleaf weeds in a single application.
• ⏳
  Long-Lasting Residual Action: Provides season-long control by suppressing weed regrowth and inhibiting tuber sprouting in sedges.
• 🌧️
  Quick Rainfastness: Absorbs into the plant system rapidly; it is rainfast within 6 hours of application.
• 🌿
  High Crop Safety: Safe for rice seedlings due to metabolic selectivity (breaks down inside the rice plant), reducing phytotoxicity risks when used correctly.

Technical Specifications

How It Works: Mode of Action

Officer works by Systemic and Residual action. It enters the weeds through leaves and roots, moving to the growing points to stop growth immediately.

1. Absorption: The WDG granules dissolve and are absorbed by weed foliage and roots.
2. Enzyme Blockage: It inhibits the ALS enzyme, which blocks the production of essential amino acids (Valine, Leucine, Isoleucine).
3. Weed Starvation: Without proteins, the weed stops growing within hours, turns yellow (chlorosis), and dies completely within 7-14 days.

Note: Rice plants naturally break down the chemical, staying safe while weeds perish.

Dosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not overdose.

Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Officer is applied at the vegetative stage, so residues are generally not found in grain.

How to Apply: Best Practices

• Timing: Apply strictly when weeds are at the 1 to 3 leaf stage (usually 10-20 days after transplanting). Do not spray on older, larger weeds.
• Water Management (Drain-Spray-Flood):
  1. Drain the field to expose weeds.
  2. Spray onto moist soil and exposed weeds.
  3. Flood the field after 24-30 hours and hold water for 5-7 days.
• Mixing (Stock Solution): Dissolve the 60g packet in a bucket with 8 mugs of water. Add 1 mug of this solution to each spray tank (15L) to ensure even distribution. Add a surfactant like Spreadmax for better results.
• Coverage: Use a Flat Fan or Flood Jet nozzle. Do not use Hollow Cone nozzles.
• Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
