More than $1.5 million in funding has been allocated to expand bio-control efforts to fight Huanglongbing (HLB), also known as citrus greening. This action is the first designation of funds by the Huanglongbing Multi-Agency Response to Devastating Citrus Disease since it was established by Secretary Vilsack in Dec 2013.

U.S. Forest Service researchers have identified what may be a key to unraveling some of the mysteries of White Nose Syndrome (WNS): the closest known non-disease causing relatives of the fungus that causes WNS. These fungi, many of them still without formal Latin names, live in bat hibernation sites and even directly on bats, but they do not cause the devastating disease that has killed millions of bats in the eastern U.S. Researchers hope to use these fungi to understand why one fungus can be deadly to bats while its close relatives are benign.

Citrus greening disease, also known as Huanglongbing, is the most serious threat to the Florida citrus industry in its history. It's costing the industry millions in losses each year, and there is no known cure for HLB and no commercially viable, effective treatments. USDAscientists have found that heating potted citrus seedlings in growth chambers can rid seedlings of HLB symptoms.

Thousand Cankers Disease Survey Guidelines Now Available (May 2013)

USDA. Animal and Plant Health Inspection Service.

In cooperation with the U.S. Forest Service, APHIS Plant Protection and Quarantine has updated the Thousand Cankers Disease (TCD) Survey Guidelines for 2013 (Mar 2013; PDF | 4.5 MB). TCD results from the combined activity of Geosmithia morbida fungus and the walnut twig beetle (WTB, Pityophthorus juglandis).

USDAscientists have developed a new cell line that rapidly and accurately detects foot-and-mouth disease virus (FMDV) which causes a highly contagious and economically devastating disease in cattle and other cloven-hoofed animals. "This important breakthrough is an example of how ARSscientists are working to improve agricultural productivity in the face of increasing demand for food," said ARSAdministrator Edward B. Knipling. "This new cell line will help in the global effort to control a disease that can cause significant economic losses."

Oranges that don't turn orange on the tree when they’re supposed to might be victims of a disease called "citrus greening," also known as Huanglongbing, or HLB. Citrus greening is especially devastating because it makes the juice bitter, so the fruit isn’t even suitable for juicing, let alone the fresh market. But Agricultural Research Service scientists have found that the same bitter juice that causes despair among growers could yield invaluable clues to how the disease works -- and how to stop it.

White-nose syndrome (WNS) which is the disease that has killed millions of bats in the eastern U.S. has been confirmed for the first time in Georgia. White-nose syndrome has been recently confirmed in South Carolina and Illinois.

A study by scientists has warned the organism responsible for the Irish potato famine is still a major threat. The team said the results showed the need for strategies to protect potatoes from disease. Phytophtora infestans is a fungus like organism that causes late blight in potatoes. It infects leaves, stems and tubers and can cause devastating crop losses.

Karnal bunt is a fungal disease that infects wheat, reducing quality and yield. Karnal bunt was first detected in the U.S. in 1996, possibly arrived from Mexico in shipments of contaminated grain.
