With toxic pesticides and chemical fertilizers saturating its farmlands, Bangladesh faces a growing public health crisis as food safety slips further out of reach.
Although these agrochemicals have played a critical role in boosting crop yields their unregulated and excessive use has raised serious concerns about safety.
Farmers across the country spray over 40,000 tons of pesticides annually, often without adequate training or awareness of safe application methods and dosages. This widespread misuse not only contaminates food but also degrades soil, pollutes water sources, and endangers non-target organisms.
Professor Abu Noman Faruq Ahmmed of Sher-e-Bangla Agricultural University said that although the Pesticide Act was enacted in 2018, Bangladesh still lacks a comprehensive pesticide policy to regulate usage and ensure safe agricultural practices.
"Bangladesh currently has over 7,500 pesticide products in the market, but misuse and overapplication are alarmingly common," he said at a recent event in Dhaka.
Environment Adviser Syeda Rizwana Hasan has said the import of pesticides rose sharply from 12,000 tons in 2005 to 27,000 tons in 2020 — more than double in 15 years.
She shared the information at a roundtable titled “Impact of climate change in the agriculture sector and way forward” organized by the Bangladesh Agricultural Reporters Forum at the National Press Club in December last year.
She said while the recommended pesticide use per hectare was valued at Tk98 the current figure has soared to Tk882.
Similarly, fertiliser application has risen dramatically from 8.5 kg per unit of land to about 700 kg.
Organic farming advocate Delowar Jahan said: "If I farm naturally, I get 10 maunds of crops; with chemicals, I harvest 25. But the cost to health and nature is not worth the gain."
While vegetable production in Bangladesh grew by 37.6% over the past decade, pesticide use rose even faster.
A comprehensive study conducted by researchers at Bangladesh Agricultural University has identified 25 highly hazardous pesticides currently registered and used in the country, raising serious concerns over public health and environmental safety.
The study, led by Prof Dr Gopal Das of the Department of Entomology, analysed 343 active pesticide ingredients following eight international benchmarks set by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO).
The findings were presented at a workshop held on July 30 in Dhaka, titled “Enhancing Capacity for Management of Highly Hazardous Pesticides and Chemicals in Bangladesh.”
Out of the 25 pesticides identified, 11 were insecticides, seven fungicides, five herbicides, and two rodenticides.
These are used in nearly 8,000 commercial formulations across the country. Among the most widely used toxic chemicals are abamectin, chlorpyrifos, paraquat, glyphosate, glufosinate ammonium, carbendazim, propiconazole, zinc phosphide and bromadiolone.
Health experts have raised alarms over the acute and chronic health risks posed by these, particularly in commonly consumed vegetables like tomatoes, beans, and eggplants. Children and adolescents are especially vulnerable.
Adding to concerns, out-of-season produce such as year-round tomatoes, beans, and cauliflower often grown using heavy chemical input has flooded local markets.
Land ownership also compounds the problem.
Nearly 85% of Bangladeshi farmers are landless, working on leased or sharecropped plots, which discourages sustainable land stewardship.
Meanwhile, government fertilizer subsidies have ballooned to Tk28,000 crore this year—four times more than last year—yet most farmers still struggle to earn a viable income.
“The agriculture system has turned into a gamble,” said Zahidul Islam, an agro-community organizer, adding: “If it were truly profitable, farmers would encourage their children to take it up. Instead, large companies and absentee landlords are buying up land, while small farmers fall deeper into poverty.”
Experts are calling for urgent reforms, including avoiding cultivation near industrial sites, regular soil and crop testing, greater consumer awareness and stronger regulatory enforcement by BFSA.
To address fertilizer demand, the government, on October 7, approved the procurement of 2.30 lakh tons of fertilizer. This includes 30,000 tons of bulk granular urea from SABIC Agri-nutrients Company, Saudi Arabia, at a cost of Tk159.99 crore.
Public health advocates urge a shift toward Integrated Pest Management (IPM), strict enforcement of withdrawal periods before harvest, support for organic farming, and consumer education on how to wash and prepare produce safely.
Mohammad Shoeb, Member of the Bangladesh Food Safety Authority, acknowledged the widespread misuse of pesticides.
“This is an open secret. We’re working to coordinate with relevant authorities to reduce usage and monitor market samples regularly. It’s not just food, but the soil and even cattle fodder have become toxic. Even the grass our livestock feed on has lost its nutritional value,” he added.
