One of the mysteries of the English language finally explained.
A weed which is extremely resistant to herbicides, especially one created by the transfer of genes from genetically modified crops into wild plants.
- ‘Fears over potential super weeds being created are misplaced - since hybrid maize would not be a weed, but merely a GM crop with increased productivity.’
- ‘Transfer of pesticide-resistant genes to related weeds may produce "super weeds" those immune to commonly used control methods.’
- ‘Even the term superweed goes back at least to 1949, in a book on hybridizing plant species.’
- ‘Opponents also raise the problem of horizontal gene transfer and the creation of ' super weeds ' and ' super pests '.’
- ‘Rice genetically modified to be resistant to pollution could potentially cross-breed with other plants to form "super weeds" that no herbicide could kill.’
- ‘In one English Nature showed that in Canada a generation of super weeds is developing.’
- ‘If a pest- or herbicide-resistant strain were to spread from crops to weeds, a "superweed" could result and be nearly impossible to stop.’
- ‘Studies into the superweed are being carried out at Eden by Camborne School of Mines scientist Dr Loveday Jenkin.’
- ‘It will in fact create more resilient super terrorists just as pesticides, herbicides and genetic engineering have created super pests and super weeds.’
- ‘I reject the notion that this is a superweed or that it will confer genetic resistance on other weeds and make them superweeds.’
- ‘Scientists tackling the thorny problem of a foreign superweed hope a humble insect could halt its rampage across UK gardens.’
- ‘The hyacinth is an aquatic plant that was introduced from Brazil in the 19th century by misguided holticulturists and has become a devastating superweed.’
- ‘A superweed that is the bane of gardeners throughout the UK could be brought under control by introducing a bug from Japan, scientists have suggested.’
- ‘The first genetically modified superweed has been discovered in Britain - the result of GM oilseed rape cross-breeding with a common weed.’
- ‘People opposed to genetically modified organisms say we're going to have super weeds taking over the world.’
- ‘Suggestions that the testing or using of genetically engineered plants may lead to production of super weeds are similarly unfounded.’
- ‘The chemical companies are bringing their spray-resistant super weeds that spread into a GE-free crop.’
- ‘She cited the loss of biodiversity, a decrease in the nutrition of the food supply and the presence of super pests and super weeds as problems.’
- ‘The super weeds have a greater resistance to widely used herbicides and will be more difficult for farmers to kill.’
- ‘We don't know that these plants won't cross-breed with wild/weed plants to create super weeds.’
