Homeland security has been a high priority during the past few years and is a major concern for us in Plant Certification. As we import large quantities of plants and plant products from overseas as well as from state to state, our goal is to reduce the incidence of pests being brought along for the ride. Hemlock Woolly Adelgid, Asian Long-horned Beetle, Emerald Ash Borer, Sudden Oak Death, Soybean Rust, and Ralstonia solancearum race 3 biovar 2 have all been identified within the United States and are cause for concern.
Sudden Oak Death
Surveys are being conducted throughout the United States to determine if sudden oak death has been shipped in from the western states. Currently in Tennessee, there are no known occurrences of Sudden Oak Death. For information on SOD in other areas of the country please follow these links.
Soybean rust was diagnosed in several southern states in 2004-2005. It has the potential to reduce yields up to 80%. If found in Tennessee, it will not live through the winter but has the potential to blow in and affect the Tennessee soybean crop year after year. For up to date information on Soybean rust visit these links.
Asian Longhorned Beetle
The State of Tennessee has been working with USDA, APHIS, PPQ to detect possible avenues of entry for Asian Longhorned Beetle. Surveys of businesses who receive crated goods from China have been conducted for two years. No ALB infestations have been identified in Tennessee. Follow this link for more information of Asian Longhorned Beetles.
Ralstonia has been detected in a few greenhouses in Tennessee. Each detection was isolated and traced back to the original source overseas. The plants were destroyed by incineration or burial in a landfill 6 feet deep. Suggested procedures were also followed to sanitize the affected greenhouses. Currently there are no known cases of Ralstonia in Tennessee.
