Coromandel Victini-Z & Pilot (Pretilachlor): Ultimate Paddy Weed Control
Stop weeds before they start. Secure your Rice yield with Coromandel’s advanced Pre-Emergence Herbicides.
Weed competition in the first 30 days can destroy up to 80% of your harvest. Victini-Z (37% EW) and Pilot (50% EC) are specialized solutions designed to form a protective chemical barrier over your paddy water, preventing stubborn grasses and sedges from ever emerging.
Best For: Transplanted Rice (Paddy) farmers looking for early-stage protection against Barnyard grass and other tough weeds.

How It Works: Mode of Action
Pretilachlor works by stopping the weeds before they can establish. It targets the "elongase" enzymes responsible for cell growth.
- Shoot Absorption: The herbicide is absorbed primarily through the shoots (coleoptile) of germinating weeds as they try to push through the treated water layer.
- Growth Blockade: It inhibits the synthesis of Very Long Chain Fatty Acids (VLCFAs), which are essential for cell division and expansion.
- Selective Safety: Rice plants naturally contain enzymes (GST) that detoxify the chemical rapidly, keeping your crop safe while weeds die.
Result: Weeds become stunted, fail to emerge, and die within days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice (Paddy) | Barnyard Grass (Echinochloa spp.) |
| Transplanted Rice (Paddy) | Sedges (Cyperus iria, Cyperus difformis) |
| Transplanted Rice (Paddy) | Broadleaf Weeds (Ludwigia, Eclipta alba) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not under-dose, as this leads to weed escapes.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Using Victini-Z) | 600 - 750 ml | 200 - 300 L (Spray) | ~ 2.5 - 3 ml | Follow Label |
| Rice (Using Pilot/Force) | 400 - 600 ml | Sand Mix Application | N/A (Sand Mix) | Follow Label |
| Rice (High Weed Pressure) | Max Label Dose | Maintain Standing Water | - | Follow Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Refer to the specific product label for the most accurate regulatory days.
How to Apply: Best Practices
- Timing: Apply within 0 to 4 Days after transplanting. Late application (after weeds have 3 leaves) will result in failure. [Image of herbicide application in paddy field]
- Mixing: For Pilot, mix 500-600ml with 20-25 kg of sand/fertilizer and broadcast evenly. For Victini-Z, spray evenly over the water surface.
- Coverage: Maintain 2-3 inches of standing water in the field for 2-3 days after application. This water distributes the chemical. Do not let the field dry out and crack!
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling spray mist.
Frequently Asked Questions
1. What is the difference between Victini-Z and Pilot?
Victini-Z is a premium 37% EW formulation (water-based) that spreads better and is safer for the crop. Pilot is the standard 50% EC formulation (solvent-based) that is highly cost-effective.
2. Can I apply this if the field is dry?
No. Pretilachlor requires standing water to work. Ensure 2-3 cm of water is present during application and retained for 48-72 hours.
3. Will it kill weeds that have already grown large?
No. It is a pre-emergence herbicide. It works best on weeds that are just germinating or are in the 1-2 leaf stage. It will not kill large, established weeds.
4. Is it safe for fish in the paddy field?
No. Pretilachlor is toxic to fish (especially catfish and carp). Do not use in fields where aquaculture is practiced alongside rice.
5. Can I use it on Direct Seeded Rice (DSR)?
These specific brands are primarily positioned for transplanted rice. For DSR, consult an agronomist as safety margins are tighter.
