Krixe Herbicide (Topramezone 33.6% SC): The Ultimate Weed Solution for Maize
Say goodbye to manual weeding and labor costs. Krixe provides advanced, selective protection for your corn fields.
Maize farming faces a constant threat from aggressive grasses and broadleaf weeds that steal nutrients and sunlight. Krixe (Topramezone 33.6% SC) by Krishi Rasayan is a new-generation, post-emergence herbicide designed specifically for Maize (Corn). It targets tough weeds that have developed resistance to older chemicals, ensuring your crop gets 100% of the nutrition it needs.

How It Works: Mode of Action
Krixe operates on a unique "Bleaching" mechanism (HPPD Inhibition) that attacks the weed's ability to process sunlight.
- Systemic Absorption: After spraying, the chemical is absorbed through leaves and roots, moving to the growing tips.
- Chlorophyll Blockage: It stops the production of carotenoids, which protect chlorophyll from the sun.
- Visual Bleaching: Without protection, the sun destroys the chlorophyll. The weed turns stark white (bleached) and dies within 10-14 days.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. You MUST use an MSO Adjuvant for Krixe to work.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Maize | 30 ml - 40 ml | 150 Litres | 0.25 ml (+ 2ml MSO) | 83 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Always mix 2ml of MSO Adjuvant per litre of water.
How to Apply: Best Practices
- Timing: Apply when weeds are at the 2 to 5 leaf stage. This is usually when the Maize crop is at the 3-5 leaf stage.
- Mixing: Use the "Pre-Cream" method. Mix Krixe + MSO in a small bucket first, then add to the main tank. Mixing Order: Water -> Atrazine (if using) -> Krixe -> MSO Adjuvant.
- Coverage: Ensure the soil is moist at the time of application for best results. Use flat fan nozzles.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Krixe without the MSO Adjuvant?
No. The weeds have a waxy coating. The MSO (Methylated Seed Oil) is mandatory to help the medicine penetrate the weed leaf. Without it, efficacy drops significantly.
2. Will Krixe damage my Maize crop?
No. Krixe is highly selective. While you might see very temporary whitening on the corn if the crop is stressed (cold/waterlog), it recovers quickly without yield loss.
3. Can I mix Atrazine with Krixe?
Yes. A common tank mix is 30ml Krixe + 500g Atrazine (50% WP) per acre. This combination creates a synergy that kills weeds faster and handles tougher broadleaf weeds.
4. What if it rains after spraying?
Krixe is rainfast within 1 to 4 hours. If it rains after this period, you do not need to respray.
5. Is Krixe cheaper than MNC brands like Tynzer?
Generally, yes. Krixe is positioned as a cost-effective domestic alternative to premium MNC brands, offering similar technical performance at a better price point for Indian farmers.
