Atrataf (Atrazine 50% WP) Herbicide by Rallis India
The Ultimate Pre-Emergence Weed Solution for Maize and Sugarcane
Atrataf is the trusted flagship herbicide from Rallis India (Tata Group). Designed specifically for coarse cereals like Maize and Sugarcane, it acts as a powerful barrier against weeds before they even appear. By controlling broad-leaf weeds and grasses during the critical first month of crop growth, Atrataf ensures your crop gets 100% of the nutrients, sunlight, and water it needs.
Best For: Farmers looking for a cost-effective alternative to manual weeding (saving up to 90% on labor costs).
Why Choose This Product? Key Benefits
- ⏱️Early Action: Stops weeds before they emerge (0-3 days after sowing), protecting the crop during its most vulnerable stage.
- ?️Tata Rallis Quality: Backed by Rallis India’s 167-year legacy, ensuring correct chemical loading and formulation stability.
- ⏳Long-Lasting Control: Provides residual control, keeping the field weed-free for the critical first 30-45 days.
- ?️Rainfastness: Works best when soil moisture is present; ideal for irrigated fields or application before light rain.
- ?Crop Safety (Selectivity): Highly safe for Maize and Sugarcane due to natural enzymes (GST) in these crops that detoxify the chemical.

How It Works: Mode of Action
Atrataf works by starving weeds of energy. It is a systemic herbicide absorbed through the roots of germinating weed seeds.
- Root Uptake: When applied to moist soil, the chemical is absorbed by the roots of weed seedlings as they try to grow.
- Photosynthesis Block: It travels up to the leaves and blocks the "Photosystem II" process. This stops the weed from converting sunlight into food.
- Elimination: Without energy, the weed turns yellow (chlorosis), dries out, and dies before it can compete with your crop.
Why doesn't it kill Maize? Maize plants have a special "superpower" enzyme called GST that breaks down Atrazine instantly, keeping the crop safe while killing the weeds.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Trianthema monogyna (Carpet weed), Digera arvensis, Amaranthus spp. |
| Sugarcane | Broad-leaf weeds, Xanthium strumarium, Annual grasses. |
| Pearl Millet (Bajra) | General broad-leaf and grassy weed complex. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Adjust dose based on soil type—use higher doses for heavy clay soils.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre)* | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Maize | 400g - 800g | 200 - 250 L | 2g - 4g | Refer to Label |
| Sugarcane | 400g - 1600g | 250 - 300 L | 2g - 5g | Refer to Label |
| Sorghum | 400g - 800g | 200 L | 2g - 4g | Refer to Label |
*Note: Since Atrataf is a powder, doses are in Grams (g). Use higher water volume for better soil coverage.
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days of sowing. It must be sprayed on the soil surface before weeds or the crop emerge.
- Mixing: Use the "Creaming Method." Mix the required powder with a little water to make a paste, then add it to the full water tank. Keep stirring.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Do not use cone nozzles. You need a uniform layer on the soil. [Image of flat fan nozzle spray pattern]
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying on windy days.
Frequently Asked Questions
1. Can I use Atrataf on Cotton or Pulses?
No. Atrataf is specific to Maize and Sugarcane. Using it on broad-leaf crops like cotton, soybeans, or pulses will kill the crop.
2. Does the soil need to be wet?
Yes. For the powder to activate and enter weed roots, soil moisture is essential. Irrigate lightly after sowing/spraying or spray after rain.
3. Can I mix it with other herbicides?
Yes. It is often mixed with 2,4-D (sequential application) or modern herbicides like Topramezone for enhanced weed control. Consult an agronomist for tank mixes.
4. Will it affect the next crop?
Atrazine has a long residual life. Be careful if you plan to plant sensitive crops like Mustard or Pulses immediately after Maize.
5. Can this be sprayed using a drone?
Yes, trials show it works with drones, but you must manage the formulation carefully to prevent nozzle clogging.
