Chrysanthemum White Rust (Puccinia horiana P. Henn) Found in Connecticut

Country: United States

Title: Chrysanthemum White Rust (Puccinia horiana P. Henn) Found in Connecticut

Dr. Anwar Rizvi, (301) 734-4313

Report: On September 13 and 14, 2007, the Animal and Plant Health Inspection Service (APHIS) confirmed Chrysanthemum White Rust (CWR) at two separate nurseries in Hartford and Fairfield Counties, Connecticut, respectively. On September 14, APHIS issued an Emergency Action Notification prohibiting movement of all host materials at both locations.

To date, State officials with the Connecticut Agriculture Experimental Station (CAES) have inspected approximately 5,900 host plants statewide for CWR and have identified signs of infection in 850 plants at the two affected nurseries. Over 1,800 infected or exposed host plants were destroyed at both facilities by incineration or burial. CAES and APHIS are following the National CWR Management Plan for Exclusion and Eradication

CWR is a quarantine significant pest in the United States under Title 7, Code of Federal Regulations, Part 319.37-2. Importation of Chrysanthemum species are prohibited from several countries, territories, and possessions due to the potential of this organism to be transported with prohibited articles of Chrysanthemum. Whenever CWR is detected in the United States, APHIS works cooperatively with the States to eradicate it.

Under IPPC Standards, Puccinia horiana is considered to be a pest that is transient, actionable, and under eradication in the United States.
