Species Profile -- Laurel Wilt
USDA. NAL.
National Invasive Species Information Center.
Laurel Wilt Disease, attacks and kills plants in the Laurel family. The disease is a fungus originally from Asia, and was first discovered in the U.S. near Savannah, Georgia in 2002. Laurel wilt is devastating to redbay and can kill nearly all mature redbay trees in a stand within 3-5 years. Laurel wilt can spread in at least two ways: one is via the redbay ambrosia beetle's natural reproduction and migration. A second way is through the sale and transport of beetle-infested wood, a result of redbay's use as firewood and for outdoor grilling.

Profile -- Dogwood Anthracnose
USDA. NAL.
National Invasive Species Information Center.
Dogwood anthracnose was first reported as a disease of flowering dogwood in the U.S. in 1978. In 15 years, it has caused serious losses to flowering dogwood found in the forest and in ornamental plantings over large portions of the Eastern and Southern United States.

Species
Profile -- Late Blight
USDA. NAL.
National Invasive Species Information Center.
Late blight is a very destructive disease and is the
same disease responsible for causing the Irish Potato Famine in the 1840s. Uncontrolled
it will kill plants faster than any other disease and effects both potato
and tomato crops. The disease spreads very easily from one garden or field to
others, because the spores are easily carried in wind currents to infect susceptible
plants.

Citrus Canker; Movement of Fruit From Quarantined Areas - Proposed rule (Jun 30, 2009)
Regulations.gov.
APHIS is proposing to amend the citrus canker regulations to modify the conditions under which fruit may be moved interstate from q quarantined area. Under this proposed rule, APHIS would eliminate the requirement that each lot of finished fruit be inspected at the packinghouse and found to be free of visible symptoms of citrus canker, and APHIS would remove the current prohibition on the movement of fruit from a quarantined area to commercial citrus-producing States. APHIS would continue to require fruit moved interstate from a quarantined area to be treated with an approved disinfectant and be packed in a commercial packinghouse that operates under a compliance agreement. These proposed changes would relieve some restrictions on the interstate movement of fresh citrus fruit from quarantined areas while maintaining conditions that would prevent the artificial spread of citrus canker.
APHIS will consider all comments received on this docket no. APHIS-2009-0023 on or before Aug 31, 2009.

Profile -- Gladiolus Rust
USDA. NAL.
National Invasive Species Information Center.
Gladiolus rust which is host specific to gladiolus plants and other closely related plant species, was first detected in the U.S. in 2006 at a floral farm in Florida. This rust disease is very damaging to gladiolus plants, and has impacts on commercial flower shipments.

Species
Profile -- White Pine Blister Rust
USDA. NAL.
National Invasive Species Information Center.
White pine blister rust is a disease that rivals chestnut blight for impact on North American ecosystems. White pine blister rust is the most serious disease of eastern white pine and young pines especially are susceptible to the disease. In North America as a whole, it has caused more damage and more money has been spent to control it than any other conifer disease. Thousands of white pine stands have been seriously damaged and many have been entirely lost.

Update of Asian Citrus Psyllid and Citrus Greening Quarantine Areas (Jan 28, 2009):
The Animal and Plant Health Inspection Service (APHIS) is expanding the Asian citrus psyllid (Diaphorina citri) (ACP) quarantine area in California and expanding the quarantine areas in Alabama, Louisiana, Mississippi, and Texas to include the entirety of those States. This action is necessary in order to prevent the interstate spread of ACP. Two parishes in Louisiana (Orleans and Washington) are now under quarantine for citrus greening (Candidatus Liberibacter asiaticus).
For more information see our Species profiles for Asian Citrus Psyllid and for Citrus Greening.

Species
Profile -- Citrus Greening
USDA. NAL.
National Invasive Species Information Center.
Huanglongbing (HLB), also known as Citrus Greening Disease,
is a bacterial plant disease that – while not harmful
to human health – destroys the production, appearance
and economic value of citrus trees and the taste of the
fruit and juice. It is the most
serious citrus plant disease in the world and once a
tree is infected, there is no cure. Diseased trees produce
bitter, inedible, misshapen fruit and eventually die.

Citrus canker is a bacterial disease that causes lesions
on the leave, stems, and fruit of citrus trees. While
not harmful to humans, the disease affects the health
and marketability of infected fruit. Citrus canker is
spread by wind and rain.

Profile -- Viral Hemorrhagic Septicemia
USDA. NAL. National Invasive Species
Information Center.
Viral hemorrhagic septicemia (VHS) virus is a serious pathogen of fresh
and saltwater fish that is causing an emerging disease in the Great Lakes region
of the United States and Canada. It causes clinical signs including internal
hemorrhaging and death in susceptible species. The disease does not pose a risk
to people, but the VHS virus can affect multiple fish species at any age.
