    Description

    When we examine the nursery survey data over the past 3 years, we find that in the western states, the number of Phytophthora ramorum-infested nurseries found via nursery inspections or surveys has dropped by more than 0 percent from 2004 to 2006, from 110 nurseries to 50, respectively. The percent of nurseries found to be infested compared to the number of nurseries inspected was at 1 to 2 percent. There were three main factors that were responsible for, or influenced, the decline from 2004 to 2006: 1. The sudden oak death Federal Order which was signed in 2004 and implemented in January 2005. 2. Grower trainings which were conducted beginning in January through March, 2004, sponsored by the California Oak Mortality Task Force (COMTF) and 3. Critical nursery research that was being identified and conducted. In order to continue the trend, the United States Department of Agriculture-Animal and Plant Health Inspection Service (USDA APHIS), National Plant Board (NPB) and the nursery industry are working together on advanced training for growers, additional inspections of high-risk plants and piloting a voluntary best management practices (BMPs) program in the three western states in 2007. Thus as the regulations are pulled back, the BMPs may serve as a stepping stone to a clean stock-like program for all interstate shippers of nursery stock in the United States.
