South Africa will ban terbufos — one of the most acutely toxic pesticides still in commercial use — starting in 2026 C.E., ending years of pressure from scientists, rural advocates, and the farmworker women who lived with the chemical’s daily dangers. The decision removes a substance the World Health Organization classifies at its highest hazard tier from a country where it had been applied routinely on staple crops.
At a glance
- Terbufos ban: South Africa will prohibit the sale and use of terbufos from the start of 2026 C.E., removing one of the most hazardous organophosphate pesticides from its agricultural market.
- Public health risk: Even trace exposures to terbufos can be fatal — children in rural farming communities were disproportionately harmed, sometimes mistaking the granular chemical for food.
- Advocacy coalition: The Center for Environmental Rights and the Rural Women’s Assembly led a multi-year campaign combining toxicological evidence with direct community testimony to push the policy across the line.
Why terbufos was so dangerous
Terbufos belongs to the organophosphate family — chemicals that disrupt the nervous systems of insects, but also of mammals, birds, and humans. The World Health Organization rates it Class Ia: “extremely hazardous,” the highest toxicity tier in its pesticide risk framework.
In South Africa, it was widely applied to maize and sugarcane in granular form. That physical resemblance to grain made it especially lethal near young children. Farm workers applying it faced acute exposure with minimal protection, and rural communities near agricultural fields had little recourse.
The E.U. and several comparable agricultural economies had already banned terbufos years before South Africa’s decision, leaving the country as an outlier. Beyond human health, the chemical accumulates in soil and water. Raptors, ground-feeding birds, and small mammals that consumed contaminated insects or grain were documented casualties — a real cost in a country with extraordinary and fragile biodiversity.
Years of evidence, finally heard
The campaign didn’t happen overnight. The Center for Environmental Rights spent years compiling poisoning data, commissioning toxicological reviews, and working alongside the Rural Women’s Assembly — an organization that gave human weight to statistics regulators might otherwise have treated as abstractions.
It was that combination — rigorous science paired with direct community voice — that ultimately moved South Africa’s Department of Agriculture, Land Reform and Rural Development to complete a formal risk review. Its conclusion: the pesticide’s hazards could not be adequately managed through labeling or protective equipment requirements alone. A full ban was the only proportionate response.
The decision aligns South Africa with international chemical safety frameworks and fits within the global trend documented by the National Agricultural Library — a steady international move away from the most hazardous pesticide classes. It also echoes commitments South Africa made when it ratified the Minamata Convention on Mercury in 2017 C.E., reflecting a broader national recognition of persistent chemical pollutants as a public health threat.
What changes — and what still needs to happen
Banning a pesticide creates an immediate practical question: what do farmers use instead? South Africa’s agricultural sector — and smallholder farmers in particular — will need accessible, affordable alternatives. That requires investment in extension services, farmer education, and potentially subsidies to ensure the transition doesn’t simply leave rural growers without tools.
Enforcement is the other open challenge. Bans on paper don’t always translate to bans in practice, especially in rural areas where supply chains are informal and regulatory reach is limited. The civil society groups that drove this campaign will likely need to stay engaged to monitor implementation and report violations — and that sustained presence isn’t guaranteed.
Those are real, unresolved issues. But the precedent is significant. South Africa has demonstrated that evidence-based advocacy — centered on the voices of farmworker communities and rural women — can shift national chemical policy. The Rural Women’s Assembly’s role here echoes a pattern emerging across the Global South: grassroots environmental advocacy producing durable, policy-level results.
For the farming communities that have lived with terbufos for decades, the arrival of 2026 C.E. will mark something real: a government that finally aligned its chemical policy with the weight of global evidence and with the testimony of the people most at risk.
