Paraquat: The Toxic Weedicide at the Intersection of Agriculture, Public Health and Regulation
The recent ban on paraquat in Telangana has reignited the debate over balancing agricultural productivity with human health and environmental safety. While farmers value the herbicide for its low cost and effectiveness, doctors and public health experts view it as one of the world's deadliest agricultural chemicals.
What is Paraquat?
| Feature | Details |
|---|---|
| Type | Non-selective contact herbicide |
| Cost | Around ₹280 per litre |
| Nature | Colourless, tasteless and highly toxic |
| Global Status | Banned in 74 countries |
| Indian Usage | Used on nearly 80 lakh acres |
"Paraquat is in a different league. It destroys the cell structure and there is no antidote." — Dr. Marri Mahesh Reddy
Why is Paraquat So Dangerous?
Unlike many poisons, paraquat has no antidote.
Effects on Human Body
- Severe corrosive injury ("Paraquat Mouth")
- Acute kidney damage
- Liver failure
- Irreversible lung fibrosis
- Multiple organ failure
- High mortality rate
Ingestion → Kidney Damage → Liver Damage
→ Lung Fibrosis → Respiratory Failure → Death
Doctors report that even advanced treatments such as Continuous Renal Replacement Therapy (CRRT) offer limited success.
A Public Health Crisis
The human cost is significant.
| Evidence | Findings |
|---|---|
| Gandhi Hospital Study | 217 poisoning cases (2024-25) |
| Farmers among victims | 54% |
| Students among victims | 16% |
| Suicide-related cases | 94% |
| Accidental cases | 5% |
A notable survivor was a Telangana employee who accidentally consumed paraquat stored in a juice bottle, highlighting the dangers of unsafe storage practices.
"There is no treatment for paraquat poisoning, only supportive care." — Dr. Krupal Singh
Why Do Farmers Continue Using It?
Despite the risks, paraquat remains popular because of structural changes in agriculture.
Key Drivers
- Rising labour shortages
- Increasing farm wages
- Quick weed removal
- Low-cost alternative
- Easy availability
Labour Scarcity
↓
Demand for Chemical Weed Control
↓
Growing Dependence on Paraquat
Paraquat imports increased from 8,598 tonnes (2019-20) to 20,786 tonnes (2022-23), indicating rapidly expanding usage.
Regulatory Challenges
The primary legislation governing paraquat is the Insecticides Act, 1968.
Recent Developments
| Year | Event |
|---|---|
| 2011 | Kerala banned paraquat |
| 2022 | Kerala HC overturned ban on technical grounds |
| Mar 2026 | Telangana banned paraquat |
| May 2026 | Andhra Pradesh followed |
| Apr 2026 | Centre cleared new formulation applications |
A major concern is the gap between state-level restrictions and nationwide regulation.
"A ban by one State without controlling online sales is just a ban on paper." — Pesticide Action Network
Global and Corporate Dimensions
The controversy extends beyond India.
Important Facts
- Paraquat was commercialised in the 1960s.
- Internal company records reportedly acknowledged its suicide risk.
- India opposed its listing under Annex III of the Rotterdam Convention in 2013.
- Over 1,500 licensed manufacturers currently operate in India.
Critics argue that economic interests have often outweighed precautionary public health measures.
Awareness Deficit
Safe-use awareness remains limited.
| Indicator | Status |
|---|---|
| Farmers trained (2020-26) | 79,185 |
| Population dependent on agriculture | 46.1% |
The mismatch suggests large sections of agricultural workers remain vulnerable to unsafe handling and accidental exposure.
Way Forward
- Impose a nationwide scientific review of paraquat.
- Strengthen pesticide regulation beyond the Insecticides Act, 1968.
- Regulate e-commerce sales of hazardous chemicals.
- Promote safer alternatives such as mechanical weed management and less toxic herbicides.
- Expand farmer awareness programmes.
- Strengthen poison surveillance and reporting systems.
- Improve packaging, labelling and storage norms.
Conclusion
The paraquat debate reflects a larger challenge facing Indian agriculture: ensuring productivity without compromising human life. While farmers require affordable weed-management solutions, public health considerations demand stronger regulation, awareness and safer alternatives. The Telangana experience demonstrates that proactive intervention can significantly reduce poisoning-related deaths and offers important lessons for national policy.
