Parizine (Atrazine 50% WP): The Pro Herbicide for Maize & Sugarcane

Protect Your Harvest with Parijat's Parizine — The Trusted Solution for Broadleaf Weed & Annual Grass Control

Parizine (Atrazine 50% WP) is a selective, systemic, and broad-spectrum herbicide from Parijat Industries. It's a trusted choice for Indian farmers for its reliable control of challenging annual grasses and broadleaf weeds, ensuring your crops get the nutrients they need to thrive.

This Wettable Powder (WP) formulation is designed for easy mixing and effective application. It works both on contact (on-leaf) and through the soil (root uptake), providing a residual barrier that protects your fields from new weed growth.

Why Choose Parizine? Key Benefits

  • ⏱️
    Flexible Application Window: Works as both a pre-emergence (before weeds sprout) and early post-emergence (on young weeds) spray, giving you more flexibility.
  • 🛡️
    Dual-Action Control: Absorbed by both the leaves (for a quick knockdown) and the roots (for residual soil action), stopping weeds from multiple angles.
  • Long-Lasting Systemic Action: Moves through the entire weed to the growing points, ensuring a complete kill and preventing costly re-growth.
  • 🌧️
    Residual Soil Barrier: Forms a protective layer in the soil that kills newly germinating weeds, keeping your field clean for longer.
  • 🌿
    Selective & Broad-Spectrum: Effectively targets a wide range of tough annual grasses and broadleaf weeds *without* harming your Maize or Sugarcane crop (when used as directed).

How It Works: Mode of Action

Parizine is a powerful systemic herbicide that stops weeds from feeding themselves.

  1. Dual Uptake: Parizine is absorbed by both the roots (pre-emergence) and the leaves (post-emergence) of target weeds.
  2. Systemic Translocation: Once inside, it moves upwards through the plant's water-conducting tissues (xylem) to the new growth, leaves, and apical meristems.
  3. Photosynthesis Inhibition: It works by blocking a key process called Photosystem II (PSII). This stops the weed from converting sunlight into energy, effectively starving it from the inside out and leading to its death.

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 ~2.0 - 3.0 g Check Label*
Sugarcane 400 - 1600 g (0.4 - 1.6 kg) 200 - 280 L ~2.0 - 6.0 g Check Label*

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always refer to the official product label for the exact PHI.

How to Apply: Best Practices

  • Timing: Apply as a pre-emergence spray (0-3 days after sowing) on clear, moist soil OR as an early post-emergence spray when weeds are small (2-3 leaf stage).
  • Mixing: Fill your spray tank with 50% of the required water. Add the recommended amount of Parizine powder, and agitate thoroughly to create a good suspension. Add the remaining water and spray.
  • Coverage: Ensure uniform spray coverage over the entire area. Use a knapsack sprayer with a flat fan or flood jet nozzle.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

Frequently Asked Questions

1. What is Parizine (Atrazine 50% WP)?
Parizine is a selective, systemic herbicide from Parijat Industries. It is CIBRC-approved to control a wide variety of annual grasses and broadleaf weeds in Maize and Sugarcane.

2. When is the best time to apply Parizine?
The ideal time is pre-emergence (0-3 days after sowing) before weeds have sprouted. It can also be used as an early post-emergence spray when weeds are very young (2-3 leaf stage).

3. Is Atrazine banned in India?
No. As of 2024-2025, Atrazine 50% WP is *not* banned. It is officially "reviewed" and approved for restricted use as per the CIBRC label (for Maize and Sugarcane only).

4. Can I use Parizine on my Cotton, Soybean, or Vegetable crops?
NO. This is illegal and highly risky. Parizine is *only* approved for Maize and Sugarcane. Using it on unapproved "off-label" crops can cause severe crop injury, total crop loss, and is not supported by the manufacturer.

5. Can I mix Parizine with other herbicides like Paraquat?
DO NOT mix Parizine with Paraquat, as it can flocculate (clump) and clog your sprayer. While it may be compatible with other common chemicals, always perform a small jar test for compatibility before mixing a full tank.
