Cornwall councillors are to be asked to pause the start of a controversial chemical weed treatment, currently scheduled for May, pending public consultation.
The vote takes place at the council meeting, in Truro, tomorrow (Tuesday). It revolves around a decision to reintroduce chemical weed treatment using glyphosate, which represents a significant policy reversal. It would have ecological, public health, and democratic implications for communities across Cornwall, councillors are told in their agenda.
The motion has been put forward by Green Newquay councillor Drew Creek, citing, among other things, a lack of consultation across all public forums ahead of the weed treatment’s scheduled introduction in May.
Across the globe, glyphosate is considered to be a significant risk to health and ecology, even when spot spraying techniques are used. Recent human epidemiological studies (March 2026) have now linked glyphosate use/exposure with development of non-Hodgkin lymphoma.
Beyond the cancer risk, glyphosate has been shown to disrupt gut microbiome health in mammals, including humans. Research has demonstrated that even low-level environmental exposure, of the kind that would result from children and pets contacting treated kerblines, can alter gut microbiome diversity. Children are disproportionately at risk due to their lower body eight, hand-to-mouth behaviour, and proximity to ground level. Pets, particularly dogs, are similarly exposed through paw contact and grooming behaviour on treated surfaces.
“These pathways of exposure are not adequately addressed by Cornwall Council’s framing that diluted application is safe for the public,” a report to the full council meeting says. Glyphosate does not degrade rapidly once it reaches the aquatic environment, either. “In Cornwall’s coastal context, this is of particular concern.”
Government consultation?
St Ives MP Andrew George, in a joint statement with North Cornwall colleague Ben Maguire, said Cornwall Council had left this matter too late to implement this season, “without generating significant avoidable controversy and undermining public trust. Nevertheless, the proposal can now be given time for sufficient further scrutiny, research, and review of the science prior to a decision taken in time to be rolled out next year.”
Given approval for the use of glyphosate in the UK expires in December 2026, this would also allow time for the UK Health and Safety Executive (HSE) to complete a thorough review of the herbicide’s safety and effectiveness before deciding on its long-term renewal.
“If the council agrees, we will consult the government, and seek the resources to — in addition to the formal HSE authorisation review — commission a thorough review of peer reviewed science into the human health, wildlifem and other environmental impacts of using glyphosate, and on the effectiveness, cost-effectiveness and practicalities of alternatives to herbicide based solutions,” the MPs add.
“We are aware that much of the science quoted in discussions has included selective material, including from sources too closely associated with companies with a commercial interest in promoting these herbicidal remedies. That’s why we would prefer to commission an independent review of all factors.”
A protest against the use of glysophate is being organised for County Hall, Truro, tomorrow, from 8.30am. Some petitions have been set up, among them this one from Redruth Town Council.
