Allaying publics worries over GMcrops
Allaying publics worries over GMcrops
GENETICALLY modified crops covered an estimated 12.1m hectares (30m acre) in North America this year. And survey results suggest those with herbicide tolerance did help cut the amount of pesticide used.
"A survey of the 8m hectares (19.7m acres) of GM glyphosate-resistant soya beans sown in the United States this year shows 39% less herbicide was used, representing a 35% reduction in the use of conventional active ingredients," says Colin Stride of Monsanto. "That demonstrates one of the environmental benefits of GM crops."
Meanwhile, in-built delays in EU and UK regulatory controls are providing a good opportunity to address consumer concerns in the UK, says Les Sykes GMO product manager for AgrEvo. He does not expect the companys herbicide resistant spring oilseed rape to be launched until 1999.
That will be four years behind the launch of the glufosinate-resistant Canola Liberty Link in Canada, which was sown on 1m hectares (2.47m acres) this year, Mr Sykes notes.
According to produce technical manager Nick Ball, Tesco received 50 letters from customers concerned about genetically modified organisms.
On-going trials should help allay those fears. Indeed, vigilance is required before GMOs are introduced into this country, comments NIABs Jeremy Sweet. As part of the approval process NIAB is co-ordinating MAFF and Department of the Environment sponsored trials and audits in co-operation with AgrEvo and Monsanto.
Those will help check whether there are any interactions between GM crops and nearby conventional crops or other plants – including wildflowers. "We mustnt have a blinkered vision about any possible downstream effects," he adds.n
