Oregon State Wasco County Extension Agent Lynn Long says the cherry fruit fly emerged on Sunday in The Dalles area.  The entire cherry-growing area, including the cities of The Dalles, Mosier, and Dufur are within a cherry fruit fly control district, and all homeowners with a backyard tree as well as commercial orchardists are required by state law to apply a control program.  Long says for homeowners recommended materials would include Spinosad and Malathion.  To obtain a free pesticide spray guide for the cherry fruit fly and other tree pests…contact the Wasco County Extension Office at 541-296-5494.
