Product scienceHow It Works: Mode of Action
Preet acts as a growth inhibitor targeting weed seedlings before they emerge from the soil.
- Uptake: The herbicide is absorbed rapidly by the shoots (coleoptiles) and roots of germinating weed seeds.
- Cellular Blockage: It inhibits the synthesis of Very Long Chain Fatty Acids (VLCFA), which are essential for cell division and cell growth.
- Elimination: Without new cells, the weed seedling stops growing, fails to emerge from the soil surface, and dies within days.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Adjust dose slightly higher for heavy clay soils and lower for light sandy soils.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Transplanted Rice | 500 ml - 750 ml | 200 Liters (Spray) or Sand Mix | 2.5 - 3.75 ml | 75 - 90 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 0 to 5 Days After Transplanting (DAT). Effectiveness drops significantly if weeds have already emerged (2-3 leaf stage).
- Mixing (Sand Method): Mix the recommended dose with 20-25 kg of dry sand or fertilizer (Urea). Broadcast uniformly over the field.
- Coverage (Water Management): Maintain 2-3 inches of standing water in the field for 3-5 days after application. This water acts as a carrier to spread the chemical and form a barrier.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not drain water immediately.

Frequently Asked Questions
1. Can I use Preet for Direct Seeded Rice (DSR)?
No. Preet 50% EC is recommended for transplanted rice. For DSR, a safener (like Fenclorim) is usually required to prevent crop injury; consult an agronomist for DSR-specific formulations.
2. What happens if it rains heavily after application?
Moderate rain is fine, but heavy rain causing water runoff can wash the herbicide away, reducing control and potentially harming nearby water bodies. Ensure field bunds are secure.
3. Can I mix Preet with other herbicides?
Yes. Farmers often mix Preet with Almix (Metsulfuron + Chlorimuron) to enhance control over broad-leaved weeds and sedges, creating a potent broad-spectrum solution.
4. Why do I need standing water?
Standing water allows the herbicide to emulsify and spread evenly across the field. It also suppresses aerobic weed germination, acting as a secondary weed control method.
5. Is there an antidote for accidental poisoning?
There is no specific antidote. Treatment is symptomatic and supportive. Note: Symptoms may mimic organophosphate poisoning, but treatment differs. Seek immediate medical attention.
