Super Racer Herbicide (Pretilachlor 37% WG)
The Advanced Pre-Emergence Solution for Weed-Free Rice Farming

Unlike older chemical formulas that can burn your crop, Super Racer uses advanced 37% WG (Water Dispersible Granule) technology. This ensures your paddy stays safe and green while tough weeds like Barnyard grass and Sedges are eliminated before they even emerge.
Best For: Farmers seeking a labor-saving, safe, and highly effective solution for transplanted rice.

How It Works: Mode of Action
Super Racer works by inhibiting the production of Very Long Chain Fatty Acids (VLCFA), which are essential for weed growth. It targets the weed at its most vulnerable stage.
- Absorption: The herbicide is rapidly absorbed by the shoots (coleoptile) of germinating weeds.
- Disruption: It stops cell division and enlargement inside the weed seedling.
- Elimination: The weed seedling dies before it can emerge above the water or soil surface, ensuring a clean field.
Note: Rice plants are naturally able to detoxify Pretilachlor, making this product safe for your crop while deadly to weeds.

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 (or g) | Sand Mix* | -- | -- |
| Transplanted Rice (Spray) | 600 ml (or g) | 200 Litres | 3 ml | -- |
*For Sand Mix: Mix 600ml of Super Racer with 10-20kg of dry sand or fertilizer and broadcast. PHI is not applicable for pre-emergence use as it degrades well before harvest.
How to Apply: Best Practices
- Timing: Apply strictly between 0 to 5 days after transplanting. Effectiveness drops significantly after this window.
- Mixing (Sand Method): Mix the granules with 10-20 kg of dry sand or urea. Broadcast evenly over the field.
- Coverage (Water Level): Ensure the field has 2-3 cm of standing water at the time of application. Maintain this water for 2-3 days without draining.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not drain water into fish ponds.
Frequently Asked Questions
1. Can I use Super Racer after weeds have already grown?
No. Super Racer is a pre-emergence herbicide. It works best before weeds emerge (0-5 days after transplanting). It will not kill established weeds.
2. Is Super Racer safer than the old "Racer" (50% EC)?
Yes. The 37% WG formulation is solvent-free, meaning it does not cause the leaf burning or stunting often seen with the older 50% EC formulations.
3. Can I drain the water immediately after application?
No. You must hold the water for at least 48-72 hours. Draining the water washes the chemical away and reduces effectiveness.
4. What if it rains after application?
Since Super Racer requires standing water to work, light rain is generally fine. Heavy rain that causes overflow may wash the product out of the field.
5. Can I mix this with Bispyribac Sodium?
Generally, no. Their application timings are different. Super Racer is for 0-5 days, while Bispyribac is typically applied later (15-25 days).
