Nakshtra Herbicide (Metribuzin 16.8% + 2,4-D 56% WP) for Sugarcane
The Ultimate "Double-Action" Solution for Tough Weeds in Sugarcane.
Nakshtra by Insecticides (India) Limited is a specialized, broad-spectrum herbicide designed specifically for Indian sugarcane farmers. It combines two powerful active ingredients—Metribuzin and 2,4-D Sodium Salt—to tackle the toughest grasses, broadleaf weeds, and stubborn sedges (Motha) in a single spray.
Best For: Controlling mixed weed populations during the critical early growth stage of sugarcane.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Weed Knockdown: Stops weed growth quickly by attacking both the leaves and the internal food systems of the plant.
-
🛡️
Double-Engine Protection: Offers dual power—Metribuzin kills grasses, while 2,4-D eliminates broadleaves and sedges.
-
⏳
Long-Lasting Control: Provides residual soil activity that prevents new weeds from germinating for weeks after application.
-
🌧️
Rainfast & Systemic: Absorbed through roots and leaves, ensuring performance even if weather conditions change post-absorption.
-
🌿
Higher Sugar Yield: By eliminating competition for sunlight and nutrients early on, it allows your cane to grow thicker and taller.

How It Works: Mode of Action
Nakshtra uses a unique "Synergistic Technology" where one ingredient opens the door for the other to strike deeper.
- Photosynthesis Blockade (Metribuzin): It stops the weed from converting sunlight into energy, causing the leaves to yellow and starve.
- Hormonal Disruption (2,4-D): It mimics plant hormones, causing uncontrolled, twisted growth that crushes the weed's internal transport system.
- Deep Translocation: The 2,4-D helps move the Metribuzin down to the roots and tubers (especially in Sedges), ensuring the weed does not grow back.
This combination creates a "Double Hit" that overwhelms the weed's defense system, preventing resistance.
Target Crops & Pests
| Crop | Target Pest(s) |

| Sugarcane | Purple Nutsedge (Motha), Cyperus rotundus |
| Sugarcane | Broadleaf Weeds: Parthenium, Bathua, Bindweed |
| Sugarcane | Grassy Weeds: Barnyard grass, Bermuda grass |
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) |
|---|---|---|---|---|
| Sugarcane | 1250 g (1.25 kg) | 200 - 250 Litres | ~ 5 - 6 g | Not Applicable* |
*PHI: Nakshtra is applied in the early vegetative stage; residue is not a concern at harvest (10-12 months later).
How to Apply: Best Practices
- Timing: Apply post-emergence when weeds are young and actively growing (at the 2 to 4-leaf stage).
- Mixing: This is a Wettable Powder (WP). Always pre-mix the powder with a little water to form a smooth slurry (paste) before adding it to the main spray tank.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Ensure high water volume (200L+) to reach the soil and cover dense weeds. Soil should be moist.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spray drift to nearby sensitive crops like cotton or vegetables.
Frequently Asked Questions
1. Does Nakshtra control Motha (Purple Nutsedge)?
Yes, the high concentration of 2,4-D Sodium Salt in Nakshtra is highly effective against sedges like Motha, suppressing their tubers.
2. When is the best time to spray Nakshtra in Sugarcane?
Spray when weeds are at the 2 to 4-leaf stage and the soil has adequate moisture. This is usually 20-40 days after planting.
3. Is Nakshtra safe for the sugarcane crop?
Yes, sugarcane has high tolerance to this formulation. However, avoid spraying directly into the plant whorl and ensure correct dosage to prevent temporary yellowing.
4. Do I need to add any sticker or spreader?
While not strictly mandatory, adding a good quality silicon-based spreader can improve coverage and absorption, especially on waxy weeds.
5. Can I use this on other crops?
No. Nakshtra is specifically recommended for Sugarcane. Using it on sensitive crops like Cotton, Vegetables, or Pulses will cause severe damage.
