New Soybeans With Seed Rot Resistance Identified
Agricultural Research Magazine (Nov/Dec 2010 - Vol. 58, No. 10)
The fungus Phomopsis longicolla is largely to blame for a disease called Phomopsis seed decay (PSD) that has claimed more than 5 million bushels of U.S. soybeans each of the past 5 years. The seed disease is most problematic in Midwestern and southern states. An Agricultural Research Service pathologist and colleagues are conducting a study to screen for PSD resistance in hundreds of soybean germplasm accessions, breeding lines, and commercial cultivars collected from around the world.  In prior field trials, the team had identified several promising PSD-resistant soybean lines from commercial varieties provided by Mississippi State University collaborators and plant introductions from the USDA Germplasm Collection.

Invading Weed Threatens Devastation to Western Rangelands (Nov 11, 2010)
Oregon State University.
A new field study confirms that the invasive weed, medusahead, has growth advantages over most other grass species, suggesting it will continue to spread across much of the West, disrupt native ecosystems and make millions of acres of grazing land almost worthless. Scientists from Oregon State University and the Agricultural Research Service conducted a comprehensive study that compared the "relative growth rate" of this invasive annual grass to that of other competing species in natural field conditions. They found that medusahead has a faster growth rate, a longer period of growth and produced more total biomass even than cheatgrass – another invading species that is a major problem, but not as devastating as medusahead.  The findings are published in the Journal of Arid Environments article Field growth comparisons of invasive alien annual and native perennial grasses in monocultures.

Invasive Hemlock Insect Found in Kittery Point (Nov 5, 2010)
Maine Forest Service.

USDA Confirms Citrus Disease in Texas and Louisiana (Aug 23, 2010)
USDA. Animal and Plant Health Inspection Service.
The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) announced the presence of Elsinoë australis. This is the first detection in the U.S. of the fungal pathogen, which poses no risk to human health. Sweet orange scab is a fungal pathogen of citrus caused by Elsinoë australis that results in unsightly, scab-like lesions developing on fruit rinds and, less often, on leaves and twigs.  The damage produced is superficial and does not affect internal fruit quality or taste. The disease was found as the result of surveys conducted under the USDA Citrus Health Response Program.

State Researchers Find New Non-Native Invasive Species (Aug 19, 2010)
Massachusetts Energy and Environmental Affairs.
A team of 20 scientists led by the Massachusetts Office of Coastal Zone Management and the Massachusetts Institute of Technology Sea Grant College Program discovered the first European shrimp to appear in North American waters, in Salem on Jul 31. The shrimp, Palaemon elegans (known as "Rock Pool Prawn" in England) is a carnivore, consuming large numbers of smaller crustaceans. The discovery was made during a Massachusetts survey to collect, identify and catalogue marine organisms in coastal waters from Cape Cod through Maine's mid-coast. Previous surveys have revealed over 30 introduced marine organisms, several of which were identified for the first time in New England coastal waters. These rapid assessment surveys help scientists identify problem areas and find solutions to prevent the spread of invasive species.

Reid: Discovery of New Species at Lake Tahoe Highlights the Need for Restoration Bill (Jun 4, 2010)
Senator Harry Reid.
Senator Harry Reid issued a statement saying that the recent discovery of the New Zealand Mudsnail at a Lake Tahoe Basin inspection station demonstrates the need for the passage of the Lake Tahoe Restoration Act. The legislation (S. 2724) represents a partnership between the federal government, Nevada, and California that will ensure funding for habitat management programs including aquatic invasive species prevention, storm water management, watershed restoration, Lahontan Cutthroat trout reintroduction, and hazardous fuels reduction.

Leek Moth Positive in St. Lawrence County, New York (Jun 22, 2010)
Cornell Cooperative Extension Community Horticulture.
Invasive leek moths have been confirmed in Canton this week. The moth attacks the onion family—garlic, leeks, onions, chives and their relatives. As reported in a story from the North County Public Radio, the leek moth originated in Europe and has been present in Ontario and Quebec since the 1990s. It first appeared in the United States in Plattsburg, New York last summer—and has now made its way to Canton.

New Zealand Mudsnails the Latest Invasive Species Detected at Lake Tahoe Basin (May 29, 2010)
Tahoe Daily Tribune.
A new aquatic invasive species has surfaced at Lake Tahoe, the New Zealand mud snail. Unlike zebra and quagga mussels, mud snails do not affect water infrastructure and cling to boat engines. The Tahoe Regional Planning Agency is stepping up inspections of boats at Lake Tahoe in an effort to keep aquatic invasive species out of it. See Protect Your Boat, Protect Lake Tahoe for watercraft inspection information.

Bat Fungus Documented in Oklahoma (May 19, 2010)
Oklahoma Department of Conservation. U.S. Fish and Wildlife Service.
A bat from a cave in northwest Oklahoma has tested positive for the fungus associated with white nose syndrome (WNS). Laboratory tests by the U.S. Geological Survey detected the genetic signature of the fungus in a single bat submitted from Oklahoma. The presentation on the Oklahoma bat was not typical of the way WNS has been observed in bats in the eastern U.S. This is the first discovery of the fungus in the state and is the most western report of the fungus. To date, all of the WNS cases have been east of the Mississippi River.

Emerald Ash Borer Found In Iowa Along Banks of the Mississippi River in Allamakee County (May 14, 2010)

USDA Confirms New Citrus Disease (citrus black spot) in Florida (Apr 8, 2010)
USDA. Animal and Plant Health Inspection Service.
APHIS confirmed the presence of Guignardia citricarpa, or citrus black spot, in Florida. Citrus black spot is a fungal disease marked by dark, speckled spots or blotches on the rinds of fruit and is an economically significant citrus disease. It causes early fruit drop, reduces crop yield and renders the highly blemished fruit unmarketable. The disease has been a production problem in Southeast Asia, Australia, South America and Africa and until now, hasn't been reported in the U.S.

Deadly Fungus (white-nose syndrome) Threatens 9 Bat Species in GA, KY, NC, SC and TN, Expert Says (Apr 7, 2010)
USDA. FS. Southern Research Station.
A leading bat expert identified nine bat species in Georgia, Kentucky, North Carolina, South Carolina and Tennessee that she believes are most threatened by white-nose syndrome (WNS), a fungus that kills bats and appears to be rapidly spreading south from the northeastern U.S. WNS has been confirmed in Tennessee, and she says it is just a matter of time before the fungus is detected in Georgia, Kentucky, North Carolina and South Carolina.

White Nose Syndrome Confirmed In Bats From Western Maryland Cave (Mar 18, 2010)
Maryland Department of Natural Resources.
Biologists have confirmed that bat carcasses collected from a cave near Cumberland on Mar 5, 2010 were infected with White Nose Syndrome (WNS). This is the first confirmed WNS case in Maryland.

Deadly Fish Virus Now Found in all Great Lakes (Jan 27, 2010)
Cornell University.
Cornell researchers report that viral hemorrhagic septicemia virus (VHS), a deadly fish virus, that was first discovered in the Northeast in 2005 has been found for the first time in fish from Lake Superior. That means that the virus has now been documented in all of the Great Lakes. On a worldwide basis, VHS is considered one of the most serious pathogens of fish, because it kills so many fish, is not treatable and infects a broad range of fish species.

Chronic Wasting Disease Found in White-tailed Deer in Virginia (Jan 20, 2010)
Virginia Department of Game and Inland Fisheries.
