What Happened
- The Telangana government issued a notification on March 31, 2026, imposing a 60-day ban on the sale, stocking, distribution, and manufacturing of Paraquat dichloride and its derivatives across the state.
- The ban followed a resolution passed unanimously by the Telangana Legislative Assembly on March 30, 2026, urging the Central government to impose a nationwide ban on the herbicide, citing its lethal impact on human health and biodiversity.
- A campaign led by Doctors Against Paraquat Poison (DAPP), based in Mancherial district, drove sustained pressure on the state government after documenting approximately 2,000 annual deaths from paraquat poisoning in Telangana alone.
- The herbicide has been linked to Parkinson's disease through established international research, which shows paraquat's toxins attack the nervous system and impair motor functions.
- Demands for a nationwide ban are now being raised by Warangal MP Dr. Kadiyam Kavya in the Lok Sabha, and the Indian Medical Association (IMA) is preparing for a national "Chalo Delhi" protest.
- Paraquat has no known antidote; it is categorised as "highly toxic" by the Central Insecticides Board and Registration Committee (CIBRC) but remains approved for use in nine crops in India.

Paraquat — Mechanism of Toxicity and Why It Has No Antidote
Paraquat (paraquat dichloride) is a non-selective, contact herbicide that acts by generating highly reactive oxygen free radicals inside plant and animal cells. In plants, it disrupts photosynthesis and kills green tissue rapidly. In humans and animals, these oxygen radicals cause severe oxidative stress, leading to irreversible damage to lungs, kidneys, and liver. The lungs are especially vulnerable because paraquat preferentially concentrates in lung tissue after ingestion, causing progressive pulmonary fibrosis (lung scarring) that often leads to death days after exposure. No antidote exists because the biochemical damage from oxidative stress cannot be reversed once it begins — supportive care only delays, not prevents, death in severe cases.
- Paraquat is classified as a WHO Class II (moderately hazardous) pesticide in terms of acute toxicity, but its no-antidote status makes even small exposures potentially fatal.
- As few as 10–20 ml of concentrated paraquat solution is sufficient to cause death in an adult.
- Paraquat has been banned in over 60 countries, including the UK (2007), EU (2007), China (2017), and Brazil.
- In India, CIBRC has approved paraquat for use in 9 crops, available as a 24% concentrated solution.
- The herbicide is widely used in India by tea, rubber, and cotton farmers as it offers low cost and fast knockdown of weeds.
Connection to this news: Telangana's ban is driven precisely by these characteristics — a highly lethal, widely available poison with no antidote, extensively documented as a driver of accidental deaths and suicides in rural Telangana.
Pesticide Regulation in India — The Insecticides Act, 1968 and CIBRC
Pesticide regulation in India is governed primarily by the Insecticides Act, 1968, which establishes the Central Insecticides Board and Registration Committee (CIBRC) as the apex regulatory body for registration, import, manufacture, sale, and use of pesticides. Registration under the Act is mandatory before any pesticide can be commercially sold in India. The CIBRC's Registration Committee evaluates safety data, efficacy, and environmental impact before granting registration. States can, under the Essential Commodities Act and Drugs & Cosmetics-related powers, impose temporary bans or restrictions on specific pesticides for public health reasons.
- India has banned approximately 27 pesticides completely; around 12 are restricted in use.
- The Pesticide Management Bill has been pending since 2008, aimed at replacing the 1968 Act with a more robust framework — it has not yet been passed.
- State-level bans, like Telangana's 60-day action, are temporary and do not override the central registration framework.
- A nationwide ban would require CIBRC review and either de-registration under the Insecticides Act or a Central Government notification.
Connection to this news: The gap between Telangana's state ban and a nationwide ban illustrates the federalism of pesticide regulation in India — states can act quickly but cannot permanently revoke central registrations.
Pesticides and Their Link to Non-Communicable Diseases — Parkinson's Disease
Parkinson's disease is a progressive neurodegenerative disorder caused by the loss of dopamine-producing neurons in the brain's substantia nigra region. Epidemiological research — including large cohort studies from the US, France, and South Korea — has consistently found a significantly elevated risk of Parkinson's disease among populations exposed to paraquat. The US Environmental Protection Agency (EPA) is currently under court pressure to ban paraquat on these grounds. The mechanism proposed is that paraquat produces a chemical (MPTP-like compound) that selectively destroys dopaminergic neurons, replicating the pathology of Parkinson's disease at cellular level.
- Farmers exposed to paraquat have a risk of Parkinson's disease 2.5 times higher than unexposed populations in key studies.
- India has an estimated 7–10 lakh Parkinson's patients; the disease burden is rising.
- The Parkinson's–paraquat link is the primary scientific basis cited by the IMA and DAPP for the nationwide ban demand.
- Syngenta, one of the world's largest manufacturers of paraquat, announced it would cease production — adding momentum to global phase-out efforts.
Connection to this news: The Parkinson's link elevates paraquat from a poisoning risk to a long-term public health hazard, strengthening the case for a national ban and connecting this agricultural issue to India's growing burden of non-communicable diseases.
