Syngenta Rifit Plus Herbicide (Pretilachlor 37% EW)
The Ultimate Pre-Emergence Safety Shield for Your Rice Crop
Don't let weeds steal your yield. Syngenta Rifit Plus is a premium, broad-spectrum pre-emergence herbicide designed specifically for Transplanted Rice. Unlike older formulations, its advanced EW (Emulsion in Water) technology ensures powerful weed control without harming your young rice seedlings. It stops competition from stubborn grasses, sedges, and broadleaf weeds before they even start.
Best For: Farmers seeking a "Green Label" safe solution that replaces labor-intensive manual weeding.

How It Works: Mode of Action
Rifit Plus acts as a growth inhibitor. It creates a chemical layer on the soil/water interface.
- Absorption: As weed seeds germinate, their emerging shoots (coleoptiles) and roots absorb the herbicide.
- Disruption: The active ingredient inhibits the synthesis of Very Long Chain Fatty Acids (VLCFA), which are essential for cell growth.
- Termination: Without these fatty acids, cell division stops, and the weed dies before it can emerge above the soil/water surface.
Note: Rice plants naturally metabolize (break down) Pretilachlor rapidly, ensuring the crop remains safe while weeds are destroyed.
Target Crops & Pests
| Crop | Target Pest(s) |

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) |
|---|---|---|---|---|
| Transplanted Rice | 600 ml | Mix with Sand/Fertilizer OR 200L Spray | 3 ml (if spraying) | 90-110 |
| Direct Seeded Rice (DSR)* | Contact Local Agronomist | Spray | - | 90-110 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. (Ideally, this product is used only at the very start of the season).
How to Apply: Best Practices
- Timing: Apply strictly between 0 to 3 days after transplanting. Do not delay, or weeds will emerge and become resistant.
- Mixing (Sand Method): Mix 600ml of Rifit Plus with 10-20 kg of dry sand or fertilizer. Broadcast uniformly across the field.
- Coverage (Water Mgmt): Ensure the field has 2-5 cm of standing water. Hold this water for 2-3 days after application to create a perfect chemical barrier.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How is Rifit Plus different from Rifit 50 EC?
Rifit Plus uses modern EW (water-based) technology, which is much safer for the rice crop. It prevents the "yellowing" or "stunting" often caused by the older, solvent-heavy 50 EC formulation.
2. Can I apply this if weeds have already appeared?
No. Rifit Plus is a pre-emergence herbicide. It works best before weeds are visible (0-3 days after transplanting). It will not kill established weeds.
3. Is it compatible with Urea/Fertilizers?
Yes, mixing the recommended dose with Urea or sand is a very common and effective application method for this product.
4. Will it harm fish in the paddy field?
While slightly toxic, it is recommended not to drain paddy water into fish ponds immediately after application. Keep the water held in the field.
5. What is the shelf life of the product?
The product typically has a shelf life of 2 years from the date of manufacture if stored in a cool, dry place.
