Paraquat Dichloride 24% SL
Paraquat Dichloride 24% SL is a broad-spectrum, non-selective contact herbicide known for delivering the fastest weed knockdown available in Indian agriculture. Belonging to the bipyridyl chemical group, it has a unique mode of action that rapidly destroys green plant tissue within hours of application, making it the preferred choice when farmers need quick, complete weed clearance before sowing, planting, or between crop rows.
How Paraquat Dichloride 24% SL Works
This herbicide works by disrupting the photosynthesis process inside the weed’s cells. Once sprayed on green plant tissue, Paraquat Dichloride interferes with the electron transport chain during photosynthesis, causing the rapid generation of superoxide free radicals. These highly reactive compounds attack and destroy the cell membranes and cytoplasm of the weed, causing rapid desiccation and collapse of all green tissue within hours. Because this process requires sunlight to activate, the herbicide works fastest on bright sunny days — another reason farmers prefer applying it in the morning when conditions are ideal for rapid weed knockdown.
Why Farmers Choose This Herbicide
One of the standout features of Paraquat Dichloride 24% SL is its exceptional speed — visible weed wilting begins within just 2 to 3 hours of spraying, and complete weed death is typically achieved within 24 to 48 hours, making it the fastest weedicide available in India by a significant margin. This is especially valuable during the pre-sowing window, when farmers need to clear weed growth from the field as quickly as possible before the next crop goes in, without having to wait days for results.
Unlike systemic herbicides that move through the entire plant and can take 7 to 14 days to show full effect, Paraquat acts purely on contact, killing only the green plant parts it directly touches. This contact-only action is actually an advantage in conservation and no-till farming, where killing only the above-ground weed growth — while leaving the root structure intact — helps prevent soil erosion and maintains the soil’s physical structure. Once it reaches the soil, Paraquat binds tightly to soil particles and is immediately inactivated, meaning the field can safely be planted within 1 to 2 days of application. Its rainfastness within just 15 to 30 minutes of spraying also makes it the top choice during monsoon season, when unexpected rain can wash away other herbicides before they have a chance to act.
Key Benefits
- Fastest weed knockdown in India — visible wilting in 2 to 3 hours
- Complete weed kill within 24 to 48 hours on a sunny day
- Non-selective broad-spectrum control of annual grasses and broadleaf weeds
- Rainfast within 15 to 30 minutes — ideal for monsoon season use
- Soil-safe — binds to soil on contact, field ready to plant in 1 to 2 days
- Ideal for no-till and conservation farming — controls foliage without disturbing roots
- Also used for pre-harvest desiccation in potato and other crops
Why Crop Nutrition Matters After Weed Clearance
After using Paraquat Dichloride 24% SL to clear weeds before sowing, giving the new crop strong nutritional support right from the start helps it establish quickly and grow well through the season. Products like Humic Acid 98% Flakes help improve soil health and root development during the early establishment phase, while Power PGR Liquid supports better flowering and fruit setting as the crop matures toward harvest.
Safety Tips & Precautions
- Paraquat Dichloride is classified as a WHO Class I hazardous chemical — handle with extreme care at all times
- Always wear full protective gear including gloves, goggles, face shield, mask, and full-sleeve clothing before handling or spraying
- Never allow the product to contact skin, eyes, or mouth — wash immediately with large amounts of water if contact occurs
- Do not eat, drink, smoke, or chew anything while handling the product
- This is a non-selective herbicide — never spray directly onto the crop, only on weeds using directed spray or inter-row application
- Use a flat-fan nozzle to spray only on green weed surfaces; avoid spray drift onto crop foliage at all times
- Apply in early morning or evening hours when wind speed is low to avoid drift
- Maintain a pre-harvest interval of at least 7 days before harvesting the crop
- In case of accidental ingestion, seek immediate medical attention — do not induce vomiting without medical advice
- Keep completely out of reach of children and animals at all times
- Store in original locked container — never transfer to food, drink, or beverage containers
Storage Instructions
Store Paraquat Dichloride 24% SL in its original sealed container in a cool, dry, locked place away from direct sunlight, heat, and moisture. Keep completely out of reach of children and animals. Never store near food, animal feed, or drinking water sources.
