The "Generic-Plus" solution for powerful broadleaf weed control in Wheat, Maize, Sorghum, and Sugarcane.
Clareo is a trusted systemic herbicide from Coromandel International Ltd. It features 2,4-D Amine Salt 58% SL, a low-volatile formulation designed to kill tough weeds without the high drift risks associated with older ester formulations. It penetrates deep into the root system to prevent weed regrowth.
Best For: Farmers looking for a cost-effective, selective herbicide to control Bathua, Motha (Sedges), and other broadleaf weeds while ensuring crop safety.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Systemic Action: Absorbed quickly by leaves and moves to the roots, killing weeds from the inside out.
-
🛡️
Higher Crop Safety: The "Amine" salt formula is low-volatile, significantly reducing the risk of vapor drift damaging neighboring sensitive crops compared to ester sprays.
-
⏳
Controls Hard-to-Kill Weeds: Highly effective against deep-rooted perennials and sedges like Cyperus rotundus (Motha).
-
🌧️
Soluble Liquid Technology: Mixes instantly with water without needing constant agitation; no dust hazards like wettable powders.
-
🌿
Cost-Effective: One of the most economical solutions on the market (approx. ₹150–₹250 per acre cost) for broad-spectrum control.

How It Works: Mode of Action
Clareo acts as a Synthetic Auxin. It mimics the plant's natural growth hormones but in an uncontrolled manner.
- Uptake: The herbicide is absorbed through the leaves and green stems of the weed.
- Translocation: It travels via the phloem (food pipe) to the growing tips and roots.
- Disruption: It triggers rapid, chaotic cell division. This crushes the plant's nutrient transport system, causing stems to curl (epinasty) and the plant to starve to death within 7-14 days.
Note: Cereal crops (Wheat, Maize) naturally detoxify the chemical, remaining safe while weeds perish.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Bathua (Chenopodium), Senji (Melilotus), Gajri (Fumaria), Hiran Khuri. |
| Maize & Sorghum | Trianthema, Pigweed (Amaranthus), Striga, and Nutsedge (Cyperus). |
| Sugarcane | Motha (Cyperus rotundus), Convolvulus, Portulaca, and other broadleaves. |
| Aquatic / Non-Crop | Water Hyacinth, Parthenium (Carrot Grass), Lantana. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not overdose, as it may stunt crop growth.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Approx. Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 300 - 500 ml | 150 - 200 L | 2.5 ml | 90-100 |
| Maize / Sorghum | 344 - 600 ml | 150 - 200 L | 3 ml | 60-70 |
| Sugarcane | 300 - 1200 ml | 200 - 250 L | 4 - 5 ml | - |
| Aquatic Weeds | 340 - 680 ml | High Volume | Mix with surfactant | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Wheat): Apply strictly 30–35 Days After Sowing (DAS). Spraying during the "Jointing" stage can deform the earheads (onion leaf symptom).
- Timing (Maize): Apply when the crop is 8–10 inches tall. Avoid spraying directly into the leaf whorl to prevent stalk brittleness.
- Mixing: Use clean water. If mixing with grassicides (like Clodinafop), perform a "Jar Test" first to check for compatibility.
- Coverage: Use Flat Fan or Flood Jet nozzles for coarse droplets. Do not use fine mist to avoid drift.
- Safety: CRITICAL: This product causes irreversible eye damage. Always wear tight-fitting goggles and gloves when mixing.
Frequently Asked Questions
1. Can I use Clareo on Cotton or Vegetables?
NO. Cotton, okra, tomatoes, and pulses are extremely sensitive. Even a small drift of vapor can destroy these crops.
2. What is the difference between Amine and Ester 2,4-D?
Clareo is an Amine salt. It is water-soluble, odorless, and much less volatile (likely to vaporize) than Ester formulations, making it safer for nearby crops.
3. How long does it take to see results?
You will see twisting and curling of weeds (epinasty) within 24 hours. Complete death of the weed occurs in 7 to 14 days.
4. Does it control Motha (Nutsedge)?
Yes, it is very effective against Motha (Cyperus rotundus), especially in Sugarcane. For best results, spray when the weed is actively growing but before flowering.
5. Is there an antidote for accidental poisoning?
There is no specific antidote. Treatment is supportive. In severe cases, doctors use alkaline diuresis to help the body excrete the toxin.
