GM crop trials should be carried out in secret or behind security fences in a bid to prevent saboteurs from ripping them out of the ground, it is claimed.
UK scientists and biotech companies are putting pressure on ministers to implement special protection measures.
They are understood to have support in government from Business Secretary Lord Mandelson, who is keen to support GM science and farming.
However, the proposals have been slammed by critics who say secret trials would expose vast areas of the country to disastrous GM contamination.
Conventional and organic farmers could find their crops are contaminated with GM pollen without any idea who is responsible.
The vast majority of consumers, supermarkets and food manufacturers in Britain and Europe have made clear they do not want GM crops and food.
Questions have been raised about GM farming techniques and their harm on the environment and beneficial insects such as bees.
Just last week, a study funded by the government of Austria suggested GM corn could harm fertility following a feeding trial with rats.
Experts at the University of Leeds claim they are being prevented from carrying out trials on GM potatoes and other crops for fear they will be wrecked by protestors.
They claim the only way to go ahead is either to keep their precise location a secret or spend many thousands of pounds on security fencing and guards.
They are considering asking a Government funding body, the Biotechnology and Biological Sciences Research Council, to stump up £100,000 for fencing.
THE GM GENOCIDE
Thousands of Indian farmers are committing suicide after using genetically modified crops
When Prince Charles claimed thousands of Indian farmers were killing themselves after using GM crops, he was branded a scaremonger. In fact, as this chilling dispatch reveals, it's even WORSE than he feared.
The children were inconsolable. Mute with shock and fighting back tears, they huddled beside their mother as friends and neighbours prepared their father's body for cremation on a blazing bonfire built on the cracked, barren fields near their home.
As flames consumed the corpse, Ganjanan, 12, and Kalpana, 14, faced a grim future. While Shankara Mandaukar had hoped his son and daughter would have a better life under India's economic boom, they now face working as slave labour for a few pence a day. Landless and homeless, they will be the lowest of the low.
"Shankara's crop had failed - twice. Of course, famine and pestilence are part of India's ancient story.
But the death of this respected farmer has been blamed on something far more modern and sinister: genetically modified crops.
Shankara, like millions of other Indian farmers, had been promised previously unheard of harvests and income if he switched from farming with traditional seeds to planting GM seeds instead."
