Northwest agriculture researchers in the U.S. say they are finding more cases of a zebra chip disease in the region's potatoes. The malady mars spuds with dark streaks, making them unsuitable for sale.

The latest case cropped up near Hermiston, Ore. First discovered in the Northwest last year, zebra chip is a grower's worst nightmare. Silvia Rondon with Oregon State University say the insects that carry the disease are the size of aphids. She says they multiply more in the summer.
