Introduction
Paraquat aqueous is a non-selective, contact herbicide widely recognized for its rapid action and high effectiveness in weed control across agricultural, industrial, and horticultural settings. It is formulated as an aqueous solution to ensure quick absorption and even distribution, making it a valuable choice for managing both annual and perennial weeds.
Fast-Acting
Visible symptoms (wilting, browning) appear within hours
Full weed death occurs within 1–3 days after application
Broad-Spectrum Effectiveness
Controls most grasses, broadleaf weeds, and woody plants
Works under various climatic and soil conditions
Non-Selective and Contact-Based
Kills green parts on contact, leaving roots unaffected
Ideal for pre-plant or directed spray use
Minimal Soil Residue
Quickly deactivates upon contact with soil
No residual impact on subsequent crops
Crop | Target | Recommended Rate | Application Stage |
---|---|---|---|
Fruit Orchards | Annual weeds | 200–300 mL/100L water | Post-emergence, directed |
Non-crop areas | Grasses & broadleaves | 1.0–2.0 L/ha | As needed |
Sugarcane, Tea, etc. | Inter-row vegetation | 300–500 mL/100L water | Avoid contact with crops |
Always follow local regulations and safety guidelines for usage.
Quick burndown of weed biomass
Ease of application with standard spraying equipment
Rainfast within 30 minutes of spraying
Enables mechanical harvesting by removing foliage quickly
Compatible with no-till farming practices
Paraquat is toxic if ingested or inhaled, so personal protective equipment (PPE) is essential.
Should be stored securely, away from children and animals.
Labeling and usage are strictly regulated in many countries due to its toxicity.
Q: Can paraquat aqueous be used on food crops?
A: It should not come into contact with edible crop parts. It's ideal for inter-row or pre-plant desiccation.
Q: Does it affect soil fertility?
A: No, paraquat deactivates on soil contact and does not affect microbes or nutrients.
Q: How is it different from systemic herbicides like glyphosate?
A: Paraquat acts only on parts it contacts; glyphosate moves through the plant. Paraquat is faster but doesn’t kill roots.
Paraquat aqueous is a reliable and fast-acting herbicide for farmers and land managers seeking immediate weed control. Its rapid action and non-persistent nature make it an ideal option when timing and environmental safety are key priorities. Proper handling and usage in accordance with safety protocols ensure both efficacy and user safety.
