Irish Famine Blight Fungus Hits Rhode Island Crops
The same virus that caused the potato blight in Ireland in the 1840s that decimated the population and drove thousands to these shores has been found in potato and tomato crops in Rhode Island.
The Providence Journal has reported that the blight has been found in crops in the state and that the Department of Environmental Management DEM has warned all growers to be aware of the problem and use fungicides to counter it.
A Time Bomb For The World Wheat Crop
The spores arrived from Kenya on dried, infected leaves ensconced in layers of envelopes.
Working inside a bio-secure greenhouse outfitted with motion detectors and surveillance cameras, government scientists at the Cereal Disease Laboratory in St. Paul, Minn., suspended the fungal spores in a light mineral oil and sprayed them onto thousands of healthy wheat plants. After two weeks, the stalks were covered with deadly reddish blisters characteristic of the scourge known as Ug99.
Crop scientists fear the Ug99 fungus could wipe out more than 80% of worldwide wheat crops as it spreads from eastern Africa. It has already jumped the Red Sea and traveled as far as Iran. Experts say it is poised to enter the breadbasket of northern India and Pakistan, and the wind will inevitably carry it to Russia, China and even North America — if it doesn’t hitch a ride with people first.
“It’s a time bomb,” said Jim Peterson, a professor of wheat breeding and genetics at Oregon State University in Corvallis. “It moves in the air, it can move in clothing on an airplane. We know it’s going to be here. It’s a matter of how long it’s going to take.”
