Nominee Gold Herbicide (Bispyribac Sodium 10% SC) by PI Industries
The "Gold Standard" Post-Emergence Weed Solution for Rice Nurseries, Transplanted Rice, and Direct Seeded Rice (DSR).
Nominee Gold is a broad-spectrum, systemic herbicide designed to replace laborious manual weeding. Powered by Bispyribac-sodium (10% SC), it provides a "rescue" solution for farmers, effectively controlling grasses, sedges, and broadleaf weeds that have already emerged. It offers a wide application window and excellent crop safety, making it the trusted choice for maximizing rice yields across India.
Best For: Controlling major weeds like Barnyard grass (Echinochloa) and Sedges in all types of rice cultivation.
Why Choose This Product? Key Benefits
- ⏱️Flexible Application Window: Apply comfortably between 15 to 25 days after sowing or transplanting (need-based application).
- ?️Broad Spectrum Control: One shot controls Grasses (like Barnyard grass), Sedges, and Broadleaf weeds simultaneously.
- ⏳Quick Rainfastness: The herbicide is absorbed rapidly and becomes rainfast within just 6 hours of spraying.
- ?️Systemic Action: Absorbed by both leaves and roots, it moves through the plant to kill weeds from the inside out.
- ?Crop Safety: Highly selective to rice plants due to metabolic detoxification (enzymatic breakdown), ensuring your crop stays safe while weeds die.

How It Works: Mode of Action
Nominee Gold works by inhibiting the ALS enzyme (Acetolactate Synthase), which is vital for plant growth.
- Absorption: Upon spraying, the active ingredient is rapidly absorbed by the foliage (leaves) and roots of the weeds.
- Translocation: It travels through the plant's system (Phloem and Xylem) to the growing points (tips and roots).
- Inhibition: It blocks the production of essential amino acids. The weed stops growing immediately, turns yellow/brown, and dies within 1-3 weeks.
Note: Rice plants contain a specific enzyme (Cytochrome P450) that breaks down the chemical quickly, keeping the crop safe.
Target Crops & Pests

|---|---|
| Rice (Nursery) | Barnyard grass (Echinochloa spp.), Sedges |

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Nursery) | 80 - 100 ml | 120 - 150 L | 0.6 - 0.8 ml | 78 |
| Rice (Transplanted) | 80 - 120 ml | 120 - 150 L | 0.8 - 1.0 ml | 78 |
| Rice (DSR) | 100 - 120 ml | 120 - 150 L | 0.8 - 1.0 ml | 78 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when weeds are at the 2 to 5 leaf stage (approx. 15-25 days after planting). Do not delay beyond the 5-leaf stage.
- Mixing: Shake the bottle vigorously before opening. Use a Flat Fan nozzle or Flood Jet nozzle for uniform coverage. Do not use cone nozzles.
- Coverage (The Drain-Spray-Reflood Method):
1. Drain the water from the field so weed leaves are exposed.
2. Spray the herbicide evenly.
3. Reflood the field after 48-72 hours and maintain water for 3-5 days to suppress new weeds. - Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Why did my rice leaves turn slightly yellow after spraying?
This is a common, temporary effect called a "Yellow Flash." It happens as the rice plant detoxifies the herbicide. The crop typically recovers fully within 10-14 days with no yield loss. A top dressing of Nitrogen (Urea) 7 days after spraying helps recovery.
2. Can I mix Nominee Gold with other chemicals?
Do NOT mix with Sulfur or Copper-containing fungicides, as this causes severe crop burn. Avoid mixing with fertilizers like Urea for broadcasting; it must be sprayed.
3. It rained 5 hours after I sprayed. Is it effective?
Yes, Nominee Gold is rainfast within 6 hours. If it rains after this period, the efficacy is generally maintained.
4. Should I spray if the field is full of water?
No. You must drain the water to expose the weed leaves. If weeds are submerged, the spray will not hit them, and they will survive.
5. What is the shelf life of the product?
The product has a shelf life of 2 years when stored under ambient conditions.
