A genetically modified variety of spud may have to be produced in Irish laboratories because of the growing threat from potato blight caused by the fungus Phytophthora infestans.
The fungal disease that wiped out the potato crop in the mid-19th century, causing more than 1m deaths, is posing a renewed menace after a more aggressive strain arrived, according to a leading scientist. This has prompted experts to intensify work, including using GM technology, to find a blight-resistant variety.

Plans for a new European Parliament law banning many pesticides would seriously affect growers, a National Farmers Union (NFU) spokesman said.
"We could lose 80% of pesticides currently available and this would end commercial production of many horticultural crops," he said.

Just by sniffing the air, an electronic nose can tell when cucumber and capsicum pepper plants are damaged – and even diagnose the problem.
The gadget can distinguish the whiff of a plant covered with caterpillars from one plagued with mites, or just physically damaged. It could act as an early warning system in glasshouses, alerting farmers to the early signs of disease before crop yields fall.

More than 3,000 farmers in Uganda have been able to combat a pestilent disease that threatened to wipe out production of cooking banana, thanks to a joint initiative by the Government and the United Nations Food and Agriculture Organization (FAO) that also helped them boost their yields of the staple crop.
The spread of banana bacterial wilt (BBW), a bacterial disease that kills off trees and makes their fruit inedible, had caused banana production in the East African nation to plummet around 65 to 80 per cent, according to FAO.

A joint Japan-U.S. research team has discovered the mechanism through which the tomato yellow-leaf curl virus spreads in infected plants, and causes a disease which has stricken the world's major tomato growing regions.
Growers currently have to discard infected tomatoes to prevent the disease from spreading, but the discovery of the pathway through which this disease is triggered at the molecular level offers hope that the disease can be prevented in the future.
