The "Promise" of a Weed-Free Harvest: Advanced Control for Rice, Tea, & Onion.
HPM Waada is a trusted, broad-spectrum herbicide designed to keep your fields clean and your crops healthy. Powered by Oxyfluorfen 23.5% EC, it works as both a pre-emergence barrier (stopping weed seeds from sprouting) and a post-emergence contact spray (burning down young weeds).
Best For: Farmers seeking an affordable, dual-action solution against tough grasses, broad-leaf weeds, and sedges in Paddy (Rice), Groundnut, and Tea plantations.
Why Choose This Product? Key Benefits
- ⏱️Dual Action Power: Works effectively before weeds grow (Pre-emergence) and kills young weeds on contact (Post-emergence).
- ?️Selective Safety: Tough on weeds but safe for crops like Rice, Onion, and Tea when used as directed (acts on contact, limited movement in plants).
- ⏳Long-Lasting Protection: Forms a chemical layer on the soil surface that prevents new weeds from germinating for weeks.
- ?️Eco-Friendly Profile: Safe for fish and earthworms, making it an excellent choice for paddy fields and sustainable farming ecosystems.
- ?Complete Weed Control: Eliminates difficult enemies like Barnyard grass (Sanwa), Pigweed, and Sedges (Motha).

How It Works: Mode of Action
Waada works using advanced Light-Activated Technology (PPO Inhibition).
- Absorption: The herbicide is absorbed by the shoots of emerging weeds or leaves of young plants.
- Activation: Once the treated weed is exposed to sunlight, the chemical triggers a rapid reaction inside the plant cells.
- Destruction: This reaction disrupts the cell membranes, causing the weed to dry out, bleach, and die quickly.
Note: Because it requires light and contact, thorough coverage of the soil or weed foliage is essential.

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 | 260 - 400 ml | 200 L | 1.5 - 2 ml | Label |
| Tea | 260 - 400 ml | 200 L | 1.5 - 2 ml | Label |
| Groundnut | 260 - 430 ml | 200 L | 1.5 - 2 ml | Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Refer to product leaflet for crop-specific timelines.
How to Apply: Best Practices
- Timing: For Pre-emergence (Rice/Groundnut), apply within 0-3 days of sowing/transplanting before weeds appear. For Post-emergence, apply when weeds are small.
- Mixing: Use clean water. Shake the bottle well before mixing. Ensure the soil has sufficient moisture for the chemical barrier to form effectively.
- Coverage: Do not disturb the soil after application. The herbicide forms a film on the surface; walking on it or raking it will break the seal and allow weeds to grow.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhalation of spray mist.

Yes, Oxyfluorfen (Waada) is generally considered safe for fish when used at recommended dosages, making it suitable for rice-fish systems.
3. Is sunlight necessary for it to work?
Yes. Waada is a PPO inhibitor, which means it requires sunlight to activate the chemical process that kills the weeds.
4. Can I mix Waada with other herbicides?
Always check the label for compatibility. Rotational use is recommended to prevent weed resistance, rather than just mixing.
