How It Works: Mode of Action
Al-Vida works by starving the weed from the inside out. It targets the enzyme system responsible for plant growth.
- Absorption: The herbicide is rapidly absorbed by the roots and leaves of the weed.
- Enzyme Block: It inhibits the ALS enzyme, which prevents the weed from producing essential proteins (Amino Acids).
- Elimination: Without proteins, the weed stops growing within hours, turns yellow, and dies completely within 1–3 weeks.
Note: Rice plants naturally break down this chemical quickly, which is why they are not harmed.

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 (g / Acre) | Water (L / Acre) | Method | PHI (Days) |
|---|---|---|---|---|
| Rice (Main Field) | 80g | NA (Sand Mix) or 150L | Broadcast with Sand/Urea OR Spray | 60-90 |
| Rice (Nursery) | 8-10g per 1000 sq.ft | As required | Spray | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
[Image of farmer broadcasting fertilizer in paddy field]- Timing: Apply between 3 to 10 days after transplanting. It works best when weeds are small (2-leaf stage).
- Mixing: The easiest method is to mix the 80g pouch with 10kg of dry sand or Urea and broadcast it manually.
- Coverage: Maintain standing water (2-3 cm) in the field for 5 to 7 days after application. This spreads the medicine to the weed roots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Al-Vida kill Grassy weeds?
It is primarily a specialist for Sedges (Motha) and Broadleaf weeds. For heavy grass infestation, it is often used alongside grass-specific herbicides.
2. Can I use it in my Rice Nursery?
Yes! Al-Vida is very safe for rice seedlings and is an excellent choice for keeping nurseries weed-free.
3. Is it better to Spray or Broadcast with Sand?
Broadcasting with sand/fertilizer is the most popular and easiest method for farmers, as long as there is standing water in the field. Spraying is also effective if water levels are low.
4. Will it affect the next crop (like Wheat or Mustard)?
No. Pyrazosulfuron-ethyl degrades quickly in the soil. There is no residual effect on the following crops in the rotation.
5. What happens if it rains after application?
Since Al-Vida is designed to work in standing water, rain generally does not reduce its efficacy, provided the water does not overflow and wash the chemical out of the field.
