Full Story
A highly toxic herbicide that poses significant health risks continues to be applied in agricultural practices across India, despite having no known antidote. Paraquat Dichloride, renowned for its lethality—where even minimal exposure can be fatal to humans—has been banned in over 70 countries due to safety concerns. Critics assert that ineffective regulatory frameworks in India have permitted the herbicide’s ongoing usage, leading to pressing questions about the safety of agricultural practices within the nation.
The central question being raised by various environmental campaigners is why India permits the agricultural use of Paraquat when 74 countries have deemed it too hazardous for use. The herbicide, first synthesised in 1882 by Austrian chemists, initially found its application as a chemical dye. However, it was not until the mid-20th century that its herbicidal properties were discovered by British researchers from Imperial Chemical Industries (ICI). Upon realising its effectiveness in eradicating plants, ICI began mass production of Paraquat in 1961 and marketed it globally a year later under the brand name Gramoxone.
In a somewhat ironic twist, the very countries that played pivotal roles in its development have since banned its use. For instance, Austria prohibited Paraquat in 1993, and the UK followed suit in 2007 due to mounting health concerns. Although the UK ceased domestic use, it continued to export the herbicide to nations like India. Switzerland, home to Syngenta—the key global manufacturer of Paraquat—implemented a ban in 1989, a move echoed by China in 2017. Despite owning Syngenta, China has since prohibited Paraquat’s domestic use.
Syngenta has indicated plans to cease global production of Paraquat by June 2026; however, the lack of a comprehensive national ban in India means that production may continue under other manufacturers. This ongoing utilisation raises significant concerns, particularly when considering that nations such as Austria, the UK, Switzerland, and numerous EU countries—including France and Germany—along with Brazil, Thailand, and Malaysia have enforced similar bans.
Champions of a prohibition argue that countries which have banned Paraquat have effectively transitioned to alternative agricultural practices that do not compromise crop yield. In India, the herbicide gained traction during the Green Revolution, a period marked by an emphasis on enhancing agricultural productivity and decreasing labour costs. The Central Insecticides Board and Registration Committee (CIBRC) sanctioned the use of Paraquat Dichloride for specific crops, including tea, potatoes, cotton, and paddy, among others.
In an attempt to address safety doubts, the Indian government instituted the Anupam Verma Committee in 2013. This committee assessed 66 pesticides banned internationally but still registered in India, including Paraquat. The review, however, concluded in 2015 with preferences to retain Paraquat’s registration, albeit under strict safety and packaging guidelines as well as medical preparedness criteria. Detractors of this decision argue that these safeguards have not been effectively enforced, leading to potential health crises.
Reports indicate that over 100 metric tonnes of Paraquat Dichloride are utilised annually in Indian agriculture. Alarmingly, in regions such as Rajasthan and Madhya Pradesh, farmers are reported to apply Paraquat in order to accelerate the drying process of crops like moong beans before harvesting, thus attempting to cut down on labour costs. Such farming practices raise significant red flags regarding the possible contamination of food supplies with hazardous residues.
The absence of a specific antidote for Paraquat poisoning exacerbates the risks associated with exposure. This factor has sparked broader discussions regarding the efficacy of India’s agricultural regulations and priorities surrounding public health. The continuing approval of Paraquat presents urgent questions regarding the government’s commitment to ensuring the safety of its citizens in the face of mounting evidence substantiating the herbicide’s dangers.
As India navigates these complex issues, it remains imperative that regulatory oversight enhances, prioritising public health and the safety of its agricultural practices. This re-evaluation is crucial as concerns continue to linger over the implications of using a substance that many nations consider too perilous to maintain within their agricultural systems. The ongoing debate surrounding Paraquat highlights the necessity for increased public scrutiny and legislative action regarding pesticide usage in India, ensuring that a balance is struck between agricultural productivity and the health of consumers.
While critiquing existing policies, it is important that discussions about Paraquat also consider the ongoing plight of farmers who may rely on such substances for their livelihoods. Effective agricultural practices must not only safeguard the health risks associated with toxic chemicals but also provide a sustainable path forward for the farming community. The future of agricultural innovation in India hinges on finding safer alternatives while addressing the realities of those who cultivate the land.
Our Thoughts
The continued use of Paraquat Dichloride in India raises significant health and safety concerns, particularly given its toxic nature and the absence of an antidote. To mitigate risks and align with best practices observed in countries that have banned the substance, India could strengthen its regulatory framework by enforcing stricter controls on the approval and usage of hazardous chemicals.
Key safety lessons include the importance of comprehensive risk assessments and robust enforcement of safety standards, which were not adequately implemented as per the Anupam Verma Committee’s recommendations. Additionally, proper training for farmers and stakeholders on the dangers associated with using such chemicals and implementing effective monitoring systems are critical steps that could have prevented these issues.
In the UK, relevant legislation such as the Control of Pesticides Regulations 1986 and the Health and Safety at Work Act 1974 emphasizes the need for safe pesticide practices and risk management. By ignoring these principles, significant regulatory gaps emerged that allowed unsafe chemicals to continue in use.
To prevent similar incidents in the future, a proactive regulatory approach, including regular reviews of pesticide safety, could ensure adherence to public health standards and align with international best practices.
