Product scienceHow It Works: Mode of Action
Ojika works by disrupting the internal "food factory" of the weed. It is absorbed through the roots and leaves, moving rapidly to the growing tips.
- Absorption: The herbicide is taken up by the weed's roots from the soil solution.
- Enzyme Block: It inhibits the ALS enzyme, which is responsible for creating essential amino acids (Valine, Leucine, Isoleucine).
- Starvation & Death: Without these proteins, cell division stops immediately. The weed turns yellow, stunts, and dies within 7-14 days.
Note: Rice plants naturally detoxify this chemical, which is why your crop stays healthy.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 80 g | Or Mix with 8-10kg Sand | ~ 0.5 g | 90 - 95 Days |
| Nursery | 8 - 10 g / 1000 sqm | Broadcast with sand | - | - |
| DSR | 80 g | Spray (150L Water) | ~ 0.5 g | 90 - 95 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices
- Timing: Apply strictly between 3 to 7 Days After Transplanting (DAT) for best results. For DSR, apply 5-10 days after sowing.
- Mixing (Sand Method): Mix the 80g packet with 8-10 kg of dry sand or fertilizer (like Urea). Broadcast evenly across the acre.
- Coverage: Maintain 3-5 cm of standing water in the field for at least 3-5 days after application. Do not drain or irrigate during this time.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

Frequently Asked Questions
1. Will Ojika damage my next crop (Wheat/Mustard)?
No. Ojika degrades rapidly in the soil. It is perfectly safe to plant sensitive rotational crops like wheat, mustard, or pulses after the rice harvest.
2. Does Ojika control grasses?
It is primarily for sedges and broadleaf weeds. For heavy grass infestation, it is recommended to use a grass-specific herbicide (like Pretilachlor) in combination or sequence.
3. Can I use it if the water has drained out?
Standing water is crucial for the "sand mix" method. If the field is just moist (no standing water), you must use a foliar spray with a Flat Fan nozzle.
4. What is the correct time to apply in Transplanted Rice?
The ideal window is 3 to 7 days after transplanting. Applying too late (after 15-20 days) will significantly reduce its effectiveness against established weeds.
5. Is the granule formulation better than powder?
Yes. The WG (Wettable Granule) formulation is dust-free, easier to measure, and disperses better in water, making it safer for the farmer to handle.
