TEXT: John Cunliffe, assistant head grower at Smith Gardens in Aurora, Oregon, inspects a 1.5 quart Princettia Pink poinsettia plant for the whitefly, a common poinsettia pest Friday November 30, 2018. Smith Gardens uses a biological approach to handling the insect by introducing beneficial predatory insects to fight the flies and reduce the need for pesticides. Cunliffe is inspecting the plants before they are packaged for one of the last shipments of the year in early December. The plants go to local big box stores.
