THE L.A. TIMES has a disturbing article by Karen Kaplan on a wheat fungus that threatens to wipe out 80% of the world's wheat crop. According to Ms. Kaplan, the Ug99 fungus, called stem rust, could wipe out more than 80% of the world's wheat as it spreads from Africa, scientists fear. The race is on to breed resistant plants before it reaches the U.S.
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.
The International Maize and Wheat Improvement Center in Mexico estimates that 19% of the world's wheat, which provides food for 1 billion people in Asia and Africa, is in imminent danger. American plant breeders say $10 billion worth of wheat would be destroyed if the fungus suddenly made its way to U.S. fields.
Fear that the fungus will cause widespread damage has caused short-term price spikes on world wheat markets. Famine has been averted thus far, but experts say it's only a matter of time.
Stem rust destroyed more than 20% of U.S. wheat crops several times between 1917 and 1935, and losses reached nearly 9% twice in the 1950s. The last major outbreak, in 1962, destroyed 5.2% of the U.S. crop, according to Peterson, who chairs the National Wheat Improvement Committee.
Well, there's always Rye.
