Srizon Herbicide (Atrazine 50% WP) | Expert Weed Control for Maize & Sugarcane
Maximize your harvest with Crystal Crop Protection's Srizon—the trusted broad-spectrum herbicide for early-season weed management.
Srizon (Atrazine 50% WP) is a powerful, selective systemic herbicide designed specifically for Maize (Corn) and Sugarcane. It tackles aggressive broadleaf weeds and suppresses grasses right at the start, ensuring your crop gets all the nutrients, water, and sunlight it needs without competition.
Best For: Farmers looking for cost-effective, residual weed control that keeps fields clean for weeks after planting.
Why Choose This Product? Key Benefits
- ⏱️Early Action: Apply Pre-emergence (0-3 days) or Early Post-emergence to kill weeds before they steal crop nutrients.
- ?️Crop Safety: Highly selective formula is safe for Maize and Sugarcane due to their natural ability to detoxify the chemical.
- ⏳Long-Lasting Protection: Provides residual soil activity, keeping your field weed-free for 30 to 100 days depending on conditions.
- ?️Broad Spectrum: Effectively targets tough broadleaf weeds like Amaranthus and Trianthema (Horse Purslane).
- ?Economical: A high-value solution that offers excellent ROI for smallholder farmers compared to expensive patent herbicides.

How It Works: Mode of Action
[Image of photosynthesis inhibition diagram in plants]Srizon works by stopping the energy production within the weed. It is absorbed through the roots and moves up to the leaves.
- Root Absorption: When applied to the soil, the herbicide is absorbed by the roots of germinating weeds.
- Photosynthesis Block: It travels to the leaves and blocks "Photosystem II," effectively stopping the plant from processing sunlight.
- Starvation & Death: Unable to create energy, the weed turns yellow (chlorosis) at the leaf tips and dies, leaving your crop to grow competition-free.
Note: Maize and Sugarcane have special enzymes that rapidly break down Atrazine, making them immune to this process.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Trianthema monogyna (Horse Purslane), Amaranthus viridis, Digera arvensis, Echinochloa spp. |
| Sugarcane | Broadleaf weeds, Annual grasses, and Portulaca oleracea. |
| General | Most effective on broadleaf weeds; moderate suppression of grasses. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Soil type matters: use lower doses for sandy soils and higher doses for clay/heavy soils.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Maize (Corn) | 400 - 800 g | 200 - 300 L | 2 - 4 g | 60 |
| Sugarcane | 400 - 1600 g | 200 - 300 L | 2 - 8 g | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply Pre-emergence (0-3 days after sowing) for best results. Soil must be moist.
- Mixing: This is a Wettable Powder (WP). Pre-mix it with a little water to form a slurry before adding to the main tank. Agitate constantly to prevent settling.
- Coverage: Use Flat Fan or Flood Jet nozzles to ensure coarse droplets hit the soil. Avoid fine mist nozzles.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the dust during mixing.
Frequently Asked Questions
1. When is the best time to spray Srizon?
Ideally, spray immediately after planting (0-3 days) before weeds emerge. It can also be used as an early post-emergence spray when weeds are very small (2-3 leaf stage).
2. Does it require rain to work?
Yes. Srizon needs soil moisture to be activated. If there is no rain within 7-10 days, light irrigation or shallow soil mixing is recommended.
3. Can I use it on other vegetables?
No. Srizon is highly specific to Maize and Sugarcane. Using it on sensitive crops like vegetables, wheat, or pulses will kill them.
4. Can I mix Srizon with other herbicides?
Yes. For better grass control in Maize, it is often tank-mixed with Metolachlor. Always perform a "Jar Test" first to check compatibility.
5. What is the waiting period for the next crop?
Since Srizon has residual activity, wait 6-10 months before planting sensitive crops like Wheat, Soybeans, or Mustard to avoid carryover damage.
