Just as a farmer's fruit should be turning juicy and sweet, an old foe called "little cherry disease" robs the harvest.
From The Dalles, Oregon, to Brewster, Washington, Northwest cherry growers are checking their orchards now, just before harvest. Infected trees have to be cut down. And the disease can spread like wildfire from tree to tree until an entire orchard is just stumps.
Small, pale, bland and bitter
Cherry industry officials estimate the disruption has already chopped 40 million pounds of cherries from the harvest. Two things are at work: A phytoplasma, that’s similar to a bacteria, and a separate virus causing similar little-cherry symptoms. They’re spread by insects like leafhoppers and mealybugs.

"They're small and pale, but they're either bland or bitter," Tianna DuPoint, with the Washington State University Extension in Wenatchee, said. "So they won't hurt you if you eat them, but they're not marketable."
Little cherry disease has devastated growers in California and Canada. Northwest farmers can request training from WSU Extension staff, or get a newly-produced booklet to help them identify the disease.
Sweet haul
The Northwest harvest begins about the end of May every year. This year there will be fewer juicy red orbs than in years past.
Nearly 21 million, 20-pound boxes are how many cherries will be picked in Washington and Oregon this year. That's down about 20% from the record-setting 2017 crop. Still, 21 million boxes is a lot of cherries. Growers are struggling with export markets and air shipments that are more complex than normal with trade wars and the coronavirus pandemic.
B.J. Thurlby leads the Northwest Cherry Growers industry group. He said exports to China will be down this year. But there is some good news.
“We’re expecting at least two million boxes just to [South] Korea, Taiwan and Vietnam,” Thurlby said. “So that should be a good export deal for us.”
Beyond trade problems, Thurlby said the crop is down largely due to little cherry disease and spring frost.
The earliest varieties in markets are likely to be Chelans, a dark red cherry, and Early Robins, a yellow Rainier-style cherry.
