Vivaya Herbicide: The Ultimate Broad-Spectrum Weed Control for Rice (Penoxsulam + Cyhalofop-butyl)
Stop weeds from stealing your yield. Vivaya is the advanced solution for mixed weed flora in Paddy.
Growing rice is hard work, and weeds are your biggest enemy. Manual weeding is expensive, and labor is hard to find. Vivaya Herbicide by Corteva Agriscience is the technological answer to these challenges. It is a powerful, post-emergence herbicide designed specifically for rice farmers to control grasses, sedges, and broadleaf weeds in a single shot.
Best For: Farmers looking for a "one-spray solution" to control tough weeds like Leptochloa (Chinese Sprangletop) and Echinochloa without hurting the rice crop.

How It Works: Mode of Action
Vivaya uses a "Double Hammer" approach to kill weeds without harming the rice plant.
- Stops Protein Growth (Penoxsulam): It absorbs into the weed and blocks the ALS enzyme. This starves the weed of essential amino acids, causing it to stop growing immediately.
- Destroys Cell Membrane (Cyhalofop-butyl): This component targets grassy weeds by blocking the ACCase enzyme, which stops the production of fatty acids needed for cell walls. The weed collapses from the inside.
- Oil Dispersion Advantage: The specialized oil formulation dissolves the waxy coating on weed leaves, ensuring the poison penetrates deep into the system for a complete kill.
Result: Weeds stop growing within days, turn yellow, and die completely within 2-3 weeks.

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 (Paddy) | 800 ml - 900 ml | 150 - 200 Litres | ~4.5 ml | 60 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply 10 to 15 Days After Transplanting (DAT) or sowing. Weeds should be small (2 to 4 leaf stage) for best results.
- Mixing: Shake the bottle well before use (OD formulation needs shaking). Drain the standing water from the field before spraying so the medicine hits the weed leaves directly.
- Coverage: Use a Knapsack sprayer with a Flat Fan or Flood Jet nozzle. Do not use a hollow cone nozzle.
- Moisture Management: Re-flood the field 24-48 hours after application to stop new weed seeds from germinating.
- Safety: Always wear PPE (gloves, mask, goggles). Vivaya can be irritating to the eyes, so eye protection is mandatory. Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Vivaya control Leptochloa (Chinese Sprangletop)?
Yes, Vivaya is highly effective (over 90% control) against Leptochloa chinensis, which many other herbicides struggle to kill.
2. Can I use Vivaya in Direct Seeded Rice (DSR)?
Yes, it is an excellent choice for DSR because it is safe for young rice seedlings and controls the complex mix of weeds found in dry fields.
3. What happens if it rains after spraying?
Vivaya is rainfast within 1 hour. If it rains an hour after you finish spraying, you do not need to spray again.
4. Why do I need to drain the water before spraying?
Vivaya is a contact and systemic herbicide. It needs to land on the leaves of the weeds to be absorbed. If weeds are submerged under water, the spray won't reach them.
5. Is it safe for fish?
No, Vivaya is toxic to aquatic life. Do not spray near fish ponds or aquaculture setups, and prevent runoff into fish-bearing waters.
