Quinzel Herbicide (Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC)
The "One-Shot" Solution for Broadleaf and Grassy Weeds in Cotton.
Struggling with labor shortages or tough weeds like Carpet Weed and Jungle Rice? Quinzel is a specialized, broad-spectrum post-emergence herbicide designed exclusively for Cotton. Powered by advanced MEC (Micro Emulsion Concentrate) technology, it absorbs faster and works harder to protect your yield during the critical 20–60 day growth window.
Best For: Farmers seeking a cost-effective alternative to manual weeding that targets mixed weed flora without harming the cotton crop.
Why Choose This Product? Key Benefits
- ⏱️Double-Engine Action: Controls both broadleaf weeds (like Trianthema) and grasses (like Echinochloa) simultaneously, eliminating the need for tank mixing.
- ?️Advanced MEC Technology: The Micro Emulsion formulation creates nano-sized droplets for superior leaf penetration, ensuring the chemical reaches the weed's roots.
- ⏳Cost-Effective: Drastically cheaper than manual labor (approx. 1/3rd the cost) with a high Benefit-Cost ratio, securing higher profits.
- ?️Rapid Rainfastness: Due to quick absorption, the product becomes rain-safe within 2 hours, reducing the risk of wash-off during monsoon season.
- ?High Crop Safety: Cotton plants naturally metabolize the herbicide into non-toxic compounds, ensuring the crop remains safe while weeds perish.

How It Works: Mode of Action
Quinzel uses a systemic "Hit-and-Stop" strategy. It enters the weed through leaves and stems, traveling to the growth points (roots and tips).
[Image of systemic herbicide translocation in plants]- Broadleaf Attack (Pyrithiobac): It inhibits the ALS enzyme, starving the weed of essential amino acids (proteins). The weed stops growing within hours and dies in 14–21 days.
- Grass Attack (Quizalofop): It targets the ACCase enzyme, stopping fatty acid production. This destroys cell membranes in grasses, causing "dead heart" and drying out the plant.
- MEC Delivery: The unique formulation dissolves the waxy coating on weed leaves, ensuring the poison gets inside even tough weeds.
Result: Weeds stop competing for food and water immediately, turning yellow/purple and eventually dying, while your Cotton crop thrives.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Major Broadleaves: Carpet Weed (Trianthema portulacastrum), Digera (Digera arvensis), Pigweed (Amaranthus viridis). Major Grasses: Jungle Rice (Echinochloa colona), Viper Grass (Dinebra retroflexa), Crowfoot Grass. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less water than recommended will result in poor weed control.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 150 - 200 Litres | 2.5 ml | Refer to Label* |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always use 150+ Litres of water to ensure the spray reaches weeds hidden under the crop canopy.
How to Apply: Best Practices
- Timing: Apply at 20–25 Days After Sowing (DAS) when weeds are at the 2 to 4 leaf stage. Weeds larger than 5 leaves may only be suppressed, not killed.
- Mixing: Shake well before use. Mix with clean water. Do NOT mix with Organophosphate insecticides (like Monocrotophos or Profenofos) as this will cause severe crop damage.
- Coverage: Use a Flat Fan or Flood Jet nozzle for uniform coating. Do not use Cone nozzles. Ensure soil is moist (good "wattar") at the time of application.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. My cotton leaves turned slightly yellow after spraying. Is this normal?
Yes, mild yellowing (chlorosis) or reddening is a common temporary effect. The cotton plant metabolizes the herbicide and will fully recover within 10–14 days without any yield loss.
2. Does Quinzel control Motha (Sedges/Nutgrass)?
No. While it may suppress Purple Nutsedge slightly, it is not designed as a sedge killer. It is specific to broadleaves and grasses.
3. Can I spray this on other crops like Vegetables?
No. This product is highly specific to Cotton. Spraying on vegetables, spinach, or mustard will kill them.
4. What if it rains after spraying?
Thanks to the MEC formulation, Quinzel is generally rainfast within 2 hours. If it rains immediately after spraying, efficacy may be reduced.
5. What crops can I plant next?
It is safe to plant Wheat (after 6 months), Maize, or Cotton in the next season. Avoid sensitive vegetable crops immediately after cotton harvest.
