Zimbabwe Launches Comprehensive Review of Glyphosate Herbicides Amid Global Safety Concerns
Zimbabwe’s Ministry of Lands, Agriculture, Fisheries, Water and Rural Development has embarked on a formal review of the safety and regulatory status of glyphosate‑based herbicides in the country. This decisive measure follows a landmark multi‑billion‑dollar settlement by Bayer, the agrochemical giant behind Roundup, after hundreds of US lawsuits claimed the widely used weedkiller caused cancer.
The global controversy has sent ripples through Zimbabwe’s agricultural sector, where glyphosate herbicides are commonly used by farmers to control weeds in an array of crops from maize to oilseeds. These products have become essential for many, offering effective weed management but also raising questions concerning health and environmental safety.
Context of the Bayer settlement and global debate
In a Missouri court, Bayer agreed to pay a staggering US$7.25 billion to resolve thousands of claims alleging its product Roundup, primarily containing glyphosate, caused non‑Hodgkin lymphoma. Despite contending the science, Bayer chose to settle to end years of legal battles and regulatory uncertainties impacting its operations in the US.
The US Supreme Court is concurrently preparing to hear arguments on whether federal regulators properly approved the herbicide. These unfolding developments underscore the global scrutiny surrounding glyphosate’s safety.
Zimbabwe government response and farmer concerns
Zimbabwean authorities were quick to respond. Professor Obert Jiri, Permanent Secretary in the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development, confirmed an ongoing review to ensure public safety against exposure risks related to glyphosate herbicides.
“We are looking at the report also,” Professor Jiri remarked, highlighting government’s intent to align national policy with emerging global evidence and precautionary principles under the National Development Strategy 1 (NDS1).
Within farming communities—from smallholder plots in Mazowe to commercial operations near Harare and Bulawayo—the announcement has sparked urgent calls for awareness and guidance on safe chemical use.
Mr Ringisai Masocha, a cereal farmer from Sealous, confessed, “We were never told about cancer risks. We just buy what works. If there are dangers, authorities should educate us so that we protect ourselves.”
Similarly, Mazowe farmer Mr Dennis Moyo stressed the need for comprehensive nationwide campaigns to inform rural farmers dependent on agro-dealers for advice.
Expert insights on glyphosate risks and safe handling
Leading Zimbabwean agrochemical expert Dr Reneth Mano, Executive Administrator at the Livestock and Meat Advisory Council (LMAC), emphasised the government’s responsibility to safeguard citizens.
“The Government of Zimbabwe is the one with the mandate and legal obligation to respond to these latest developments by taking appropriate policy action to protect citizens from exposure to such cancer‑causing agro‑chemicals,” Dr Mano stated unequivocally.
Veteran agronomist Mr Ivan Craig, with decades of field experience, offered practical counsel to farmers.
“Glyphosate-based herbicides are effective and popular but must be handled with extreme caution,” he advised. “These chemicals can be quite dangerous if misused or mishandled.”
Mr Craig urged adherence to label instructions, strict compliance with application rates, and mandatory use of protective clothing.
“Farmers often underestimate long-term health risks. The damage can be slow and cumulative, including skin cancer, if safety precautions aren’t followed,” he explained.
He also underscored the importance of understanding cropping programmes and supply chain requirements:
- “Residues can affect germination of subsequent crops in rotation.”
- “Export markets increasingly test for chemical residues and may reject produce that fails to meet safety standards.”
A Zimbabwean case study: sustainable weed management challenges and opportunities
The story of Ms Tanyaradzwa Chikwenya, a smallholder farmer from Manicaland, provides vivid insight into the realities faced by Zimbabwe’s agricultural family sector.
For years, Ms Chikwenya relied on glyphosate herbicides to control weeds in her maize and groundnut fields. She found the products affordable and readily accessible in her local agro-dealer shop. However, after hearing recent safety concerns, she began to question their use.
“I want to protect my family and farm workers. If these chemicals pose risks, I need alternatives and training on their use,” she said. Her experience highlights the urgent need for farmer education and government extension services tailored for women, youth, and rural communities.
Policy alignment and future pathways for Zimbabwe agriculture
The review launched by Zimbabwe’s Ministry signals a commitment to protecting public health while balancing the needs of agriculture—a crucial sector for national food security and economic growth. This is aligned with Zimbabwe’s National Development Strategy 1 (NDS1), which prioritises sustainable agriculture, rural livelihoods, and innovations in farming practices.
Potential policy actions could include:
- Rigorous scientific evaluation of glyphosate products’ safety in Zimbabwean conditions.
- Enhanced regulatory oversight and transparent labelling requirements.
- Development and promotion of safer, alternative weed control technologies, including integrated pest management.
- Nationwide farmer education campaigns focused on chemical safety and environmental stewardship.
- Targeted support for women and youth farmers to access knowledge and safer agrochemical alternatives.
Harnessing such approaches can accelerate Zimbabwe’s transition toward climate-smart and health-conscious farming methods, safeguarding both producers and consumers.
Conclusion: Awareness, safety, and responsible use
As glyphosate-related court cases unfold globally and scientific debates continue, Zimbabwe stands at a pivotal junction in agrochemical policy. The government’s review is a welcome step in protecting human health and upholding the integrity of Zimbabwe’s agriculture.
For farmers across the country, knowledge and caution will be their best tools. Wearing protective gear, following label directions, and staying informed through official channels will help mitigate risks.
Most importantly, inclusive dialogue involving government authorities, agricultural experts, agro-dealers, and farmers—especially women and youth—will shape a safer, more sustainable future for Zimbabwean agriculture and rural communities.
FFA Explainer:
Glyphosate is a broad-spectrum systemic herbicide widely used to control weeds. It works by inhibiting a specific plant enzyme needed for growth, effectively killing unwanted plants. However, concerns have emerged linking glyphosate to certain cancers, especially non-Hodgkin lymphoma, leading to global debates about its safety and regulatory status.
