Welcome to your ultimate guide for Atranex WP, a trusted and highly effective herbicide formulated by ADAMA.
If you are struggling with aggressive weeds choking your maize, sorghum, or sugarcane crops in the first 30 to 45 days, this Atrazine 50% WP solution is exactly what you need. By creating a strong chemical barrier in the soil, it stops competitive broadleaf weeds and grasses before they even break the surface.
Boost your crop yields, save up to 90% on expensive manual labor, and keep your fields clean all season long with this foundational crop protection solution.
Why Choose This Product? Key Benefits
- ⏱️Fast & Lasting Weed Control: Delivers powerful pre-emergence and early post-emergence action to eliminate weeds before they steal vital nutrients and sunlight.
- 🛡️100% Crop Safe: Naturally neutralized by the internal enzymes (GST) of maize and sugarcane, keeping your main crops completely unharmed while weeds are destroyed.
- ⏳Extended Soil Protection: Forms a durable, residual barrier in the topsoil that suppresses new weed seed germination for weeks after the first application.
- 🌧️Moisture Activated: Works beautifully with natural soil moisture to travel straight to the weed's roots for maximum, systemic impact.
- 🌿Broad-Spectrum Power: Effectively kills a massive variety of tough, yield-robbing broadleaf weeds and annual grasses.

How It Works: Mode of Action
Atranex WP eliminates weeds by starving them of energy. Here is the step-by-step process:
- Rapid Root Absorption: Once applied to moist soil, the active ingredient dissolves and is quickly taken up by the roots of germinating weed seeds.
- Upward Movement: As the weed grows, it naturally pulls the herbicide up into its stems, leaves, and green tissues.
- Photosynthesis Blockout: The chemical immediately shuts down the weed's ability to produce energy from sunlight. The leaves quickly turn yellow or bleach white, leading to the rapid death of the plant.
*Note: Maize and sugarcane have naturally high levels of detoxifying enzymes, which safely break down the herbicide before it can harm the crop.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Horse purslane, Slender amaranth, Common cocklebur, Jungle rice, Goosegrass, Crabgrass |
| Sugarcane | Common purslane, Crabgrass, Pigweed, and broadleaf weeds |
| Sorghum | Early-season annual grasses and broadleaf weed varieties |
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 (g / Acre)* | Water (L / Acre) | Dose (g / Litre)* | PHI (Days) |
|---|---|---|---|---|
| Maize | 400 - 800 g | 200 - 280 L | 2 - 3 g | Refer to Label |
| Sugarcane | 400 - 1600 g | 200 - 280 L | 2 - 6 g | Refer to Label |
| Sorghum | 400 - 800 g | 200 - 280 L | 2 - 3 g | Refer to Label |
*Note: Header adjusted to grams (g) as Atranex WP is a solid powder formula. PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply strictly within 3 days of sowing the seeds (pre-emergence) before either the crop or the weeds break the soil surface. It can also be used as an early post-emergence spray.
- Mixing: Always use the "pre-slurry" method. Mix the powder with a small amount of clean water in a bucket to form a smooth, lump-free paste. Fill your spray tank halfway with water, turn on agitation, and slowly add your paste.
- Coverage: Use a high volume of water (at least 200 liters per acre) and ensure the soil is moist. A continuous, even spray creates the perfect weed-blocking barrier. Do not apply through drip irrigation.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Keep spray away from windy conditions to avoid drift.
Frequently Asked Questions
1. Can I mix Atranex WP with other herbicides?
Yes! It works brilliantly in tank mixtures with advanced herbicides like Tembotrione. This combination creates a double-knockout punch, killing tough weeds and managing herbicide resistance effectively.
2. Will this herbicide damage my maize or sugarcane?
No. These specific crops have natural internal enzymes that instantly detoxify Atrazine. Your harvest stays 100% safe while the surrounding weeds die.
3. What happens if I just dump the powder directly into the spray tank?
Because it is a Wettable Powder (WP), failing to make a "slurry paste" first will cause dense chemical lumps at the bottom of the tank. This clogs your spray nozzles and results in poor, uneven weed control.
4. How does the weather affect the application?
Atranex needs moist soil to activate properly. However, avoid spraying right before a heavy, torrential rain, as this can wash the protective chemical barrier away from the weed root zone.
5. Will it harm the next crop I plant in this field?
When applied at the recommended doses, it will not leave harmful residues that affect delicate rotational crops like wheat, mustard, or greengram in the following season.
