Rukawat-X Herbicide (Quizalofop Ethyl 10% EC) – Coromandel
The Ultimate "Gromor Suraksha" Against Stubborn Grassy Weeds.
Rukawat-X is a premium, post-emergence systemic herbicide designed to protect your broadleaf crops. Manufactured by Coromandel International, this advanced 10% EC formulation is twice as concentrated as older generic alternatives. It specializes in destroying tough grassy weeds like Echinochloa (Sanwa) and Wild Cane without harming your Soybean, Cotton, or Groundnut crops.
Best For: Farmers seeking rapid, rainfast, and systemic removal of grasses to boost crop yield.

Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Rukawat-X |
| Technical Name | Quizalofop Ethyl 10% EC |
| IRAC MoA Code | Group 1 (Formerly Group A) |

How It Works: Mode of Action
Rukawat-X works by targeting the specific biological machinery found only in grasses.
- Absorption: Upon spraying, the ester formulation penetrates the waxy leaves of the weed within 1 hour.
- ACCase Inhibition: The chemical blocks the ACCase enzyme, which is responsible for producing lipids (fats) essential for cell growth.
- Systemic Death: It travels to the growing points (meristems). Weeds stop growing in 2 days, turn purple/red in 5-8 days, and completely rot from the core within 10-15 days.
Note: Broadleaf crops are naturally immune because their enzymes are structured differently.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean & Black Gram | Barnyard Grass (Sanwa), Crowfoot Grass (Makra), Volunteer Cereals |
| Cotton | Crabgrass, Goosegrass, Viper Grass, Bermuda Grass (Suppression) |
| Groundnut & Onion | Love Grass, Digitara spp., and other narrow-leaf annual weeds |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Use Flat Fan or Flood Jet nozzles for best coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 150 - 180 ml | 150 - 200 L | 1 ml | 90 - 100* |
| Cotton | 180 - 200 ml | 150 - 200 L | 1 - 1.2 ml | 80 - 90* |
| Groundnut/Onion | 150 - 180 ml | 150 - 200 L | 1 ml | 85 - 95* |
*PHI = Pre-Harvest Interval. Since Rukawat-X is applied in the early vegetative stage, the PHI is naturally satisfied by harvest time.
How to Apply: Best Practices
- Timing: Apply when weeds are young and actively growing (2 to 4 leaf stage). Do not spray on stressed weeds (drought/heat).
- Mixing: Compatible with Imazethapyr for broad-spectrum control in Soybean. Add Rukawat-X last in the tank mix.
- Coverage: Use sufficient water (150-200 Liters/acre) to ensure the spray droplets slide down into the weed whorls.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Toxic to fish—avoid use near ponds.
Frequently Asked Questions
1. Does Rukawat-X control broadleaf weeds?
No. It is a selective herbicide only for grassy (narrow leaf) weeds. For broadleaf weeds in Soybean, you can tank-mix it with Imazethapyr.
2. How long before it rains is it safe to spray?
Rukawat-X is rainfast within 1 hour. If it rains 60 minutes after spraying, re-application is not needed.
3. Can I use it on Maize or Paddy?
No! Maize and Paddy are grasses. Rukawat-X will kill them. Only use it on broadleaf crops like Soybean, Cotton, Groundnut, and Pulses.
4. Why do weeds turn purple after spraying?
This is a sign the product is working. The herbicide stops fatty acid production, causing the weed to accumulate pigments (anthocyanins) before it fully rots and dies.
5. What is the difference between Rukawat-X and older Quizalofop brands?
Rukawat-X is a 10% EC formulation, while older brands are 5% EC. This means Rukawat-X is more concentrated, requires less dosage per acre, and uses fewer harmful solvents.
