Apple, pear and grape production in the U.S. should fall in 2010, according to a new U.S. Department of Agriculture report.

About 9.5 billion pounds of apples, 4% less than last year, should be produced in 2010, according to the USDA’s National Agricultural Statistics Service’s Aug. 12 Crop Production report.

Poor growing conditions in the eastern half of the country is the main reason for the drop. Michigan, the No. 3 producer, is expected to produce 47% fewer apples than last year. New York, the second-largest apple producer, is projected for a 13% drop, and Pennsylvania expects a 4% decline.

Production in the top-producing state, Washington, is expected to be up in 2010-11. About 5.7 billion pounds are expected out of Washington, 5% more than in 2009-10.

Production in California is expected to jump 17%, to 310 million pounds.

U.S. pear production also is expected to fall in 2010-11, according to the report. About 855,000 tons are expected, 11% fewer than last year.

Bartlett production in Washington is expected to be down 9% from last year. California is projected to produce 8% fewer bartletts. Production of all other Washington pear varieties is expected to fall 12%.

Grape production also is expected to decline in the U.S. this year, according to the report. About 7 million tons are forecast for 2010, 3% fewer than last year.
