How It Works: Mode of Action
Waada uses sunlight to destroy weeds. It is a PPO Inhibitor that targets the weed's cell membranes.
- Contact: Upon spraying, the chemical forms a layer on the soil or coats the weed foliage.
- Sunlight Activation: When the weed is exposed to sunlight, the chemical triggers the release of active oxygen.
- Destruction: These oxygen molecules burst the weed's cell walls, causing it to dry out and die rapidly (desiccation).
Note: Because it needs light to work, it is highly effective on sunny days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|

| Onion & Tea | Amaranthus (Pigweed), Chenopodium (Bathua), Broadleaf weeds |
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) | 260 - 410 ml | 200 L | ~2 ml | Per Label |
| Groundnut | 260 - 430 ml | 200 L | ~2.5 ml | Per Label |
| Tea & Onion | 300 - 400 ml | 200 L | ~2 ml | Per Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Refer to the product leaflet for crop-specific days.
How to Apply: Best Practices
- Timing (Rice): Apply within 0 to 3 days after transplanting or sowing. This "Pre-Emergence" window is critical.
- Mixing: Mix the liquid well with clean water. Avoid using muddy water as it can reduce effectiveness.
- Coverage: Spray uniformly over the soil surface. The chemical needs to form an unbroken layer on the dirt to stop weed seeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How does Waada differ from other herbicides?
Waada is a "contact" herbicide that creates a chemical barrier on the soil. It kills weeds as they emerge and touch this barrier, unlike systemic herbicides that travel inside the plant.
2. Will Waada damage my crops?
It is safe for labeled crops (Rice, Onion, etc.) if applied before the crop seedlings emerge or as a directed spray. Avoid spraying directly on the leaves of young sensitive crops.
3. Is this effective against grassy weeds in Paddy?
Yes, it is highly effective against Barnyard grass (Echinochloa), which is the most common and damaging weed in rice fields.
4. What happens if it rains after spraying?
Waada binds tightly to soil particles. Once it settles on the soil, it is resistant to leaching, meaning it won't wash away easily or damage crop roots deep in the soil.
5. Is this product related to the Haryanvi songs?
No. While "Waada" means promise and is popular in music, this is a specialized agricultural product manufactured by HPM Chemicals & Fertilizers Ltd. for crop protection.
