Coromandel Weedax Herbicide (Paraquat Dichloride 24% SL)
The fast-acting, non-selective contact herbicide for effective weed control in field and plantation crops.
Weedax by Coromandel International is a powerful solution designed to solve labor shortages and reduce weeding costs. It contains Paraquat Dichloride 24% SL, a contact herbicide that burns down green plant tissue on contact. It is ideal for clearing weeds before planting (zero tillage) or managing undergrowth in tea and coffee plantations. Because it becomes inactive as soon as it touches the soil, it is safe for your next crop.
Why Choose This Product? Key Benefits
- ⏱️Super Fast Action: Visible results appear within hours. It works by "sunburning" the weeds from the inside out.
- ?️Soil Safe (No Residuals): The chemical becomes inactive immediately upon touching soil. You can sow your next crop right after spraying without fear of damage.
- ⏳Labor & Cost Saver: A cost-effective alternative to manual weeding, helping you manage large fields despite labor shortages.
- ?️Rainfast: Absorbs quickly into the leaf. Rain occurring shortly after application does not wash it away or reduce its power.
- ?Broad Spectrum Control: Effectively kills a wide variety of grasses, broadleaf weeds, and sedges across varying terrains.

How It Works: Mode of Action
- Contact Action: Weedax is a "contact" killer. It does not move inside the plant to the roots. It only kills the green parts it touches.
- Photosynthesis Block: It enters the leaves and intercepts electrons during photosynthesis (specifically Photosystem I).
- Cell Destruction: This reaction creates free radicals that rupture the plant's cell membranes, causing the weed to dry up and die rapidly (necrosis).
Note: Because it is a contact killer, thorough coverage of the weed foliage is essential for success.

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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | 325 - 1700 ml | 200 Litres | 1.6 - 8 ml | -- |
| Rice (Pre-plant) | 500 - 1400 ml | 200 Litres | 2.5 - 7 ml | -- |
| Wheat / Maize | 700 - 1700 ml | 200 Litres | 3.5 - 8.5 ml | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Water volume is an estimate based on standard 500L/Ha calibration.
How to Apply: Best Practices
- Timing: Apply when weeds are actively growing (2-3 leaf stage) for best results. For crops like Tea, use a directed spray to avoid hitting the tea bushes.
- Mixing: Use clean water. Do not mix with alkaline substances or anionic surfactants (soaps), as this will deactivate the chemical.
- Coverage: Ensure the weed is completely wet. Since it doesn't move inside the plant, parts of the weed not sprayed will not die.
- Safety: Always wear PPE (gloves, mask, goggles, boots). Wash hands thoroughly after use. Never transfer liquid to food/drink bottles.
Frequently Asked Questions
1. Is Weedax safe for the soil?
Yes. Weedax has a unique "soil inactivation" property. It binds tightly to clay particles in the soil and becomes biologically inactive, so it won't harm the seeds you plant next.
2. Can I mix Weedax with other pesticides?
You must be very careful. Do not mix it with alkaline products. It is generally recommended to spray Weedax alone to ensure maximum efficacy.
3. How fast will I see results?
Weedax is extremely fast. You will often see weeds withering and turning yellow within a few hours of application.
4. Why is the liquid blue and smelly?
Safety features are added intentionally. The dark blue color helps distinguish it from water or tea. The "stenching agent" creates a bad smell to prevent accidental drinking.
5. Is there an antidote for accidental swallowing?
No. There is no specific antidote for Paraquat. This is why wearing protection and storing it safely away from children is critical.
