Since destructive pests are often impossible to control once established, early detection is key to stopping their spread ARLINGTON, Va., April 7 /PRNewswire-USNewswire/ -- Until proposed revisions to the regulations governing international plant trade, currently under review, are approved by the U.S. Department of Agriculture (USDA), homeowners can play an important role in detection and reporting of invasive insects and diseases. New non-native plant pest introductions are detected at a...

URBANA "“ University of Illinois researchers may have debunked the myth that foliar fungicides can improve corn's tolerance to hail damage. In 2009, the U.S. Environmental Protection Agency granted a supplemental label registration for use of Headline fungicide on registered crops for disease control and plant health. This label stated that the fungicide can provide a benefit of "better tolerance to hail" in corn. "When these recommendations began to surface, I was not aware of any data...

An international team led by scientists at the Sainsbury Laboratory in Norwich, UK, have transferred broad spectrum resistance against some important plant diseases across different plant families. This breakthrough provides a new way to produce crops with sustainable resistance to economically important diseases. Food insecurity is driving the search for ways to increase the amount of food we grow, whilst at the same time reducing unsustainable agricultural inputs. One way to do this is to...

Americans love potatoes, consuming about 130 pounds per person annually. But it's a wonder the spuds even make it to the dinner table, given the many fungal diseases that attack the tuber crop"”powdery scab and black dot among them. Now, five new potato breeding lines being tested by Agricultural Research Service (ARS) scientists and collaborators could open the door to new varieties of the crop that resist powdery scab and black dot diseases, caused by the fungi Spongospora subterranea...

ST. PAUL, Minn., Jan. 28 /PRNewswire-USNewswire/ -- Huanglongbing (HLB), or Citrus Greening Disease, a major threat native to Asia, has rapidly globalized in recent years, devastating citrus crops in the Americas, Europe, Africa, and other parts of the world. In December 2008, the international research community responded to this threat by inviting colleagues, regulatory agency representatives, and commercial industry leaders to Orlando, Florida, so they could exchange the latest...

When it comes to plants' innate immunity, like many of the dances of life, it takes two to tango. A receptor molecule in the plant pairs up with a specific molecule on the invading bacteria and, presto, the immune system swings into action to defend against the invasion of the disease-causing microbe. Unwrapping some of the mystery from how plants and bacteria communicate in this dance of immunity, scientists at the University of California, Davis, have identified the bacterial signaling...

Two Iowa State University researchers are examining a new method of controlling soybean aphids without the use of chemical pesticides. Bryony Bonning, professor of entomology, and Allen Miller, professor of plant pathology and director of the Center for Plant Responses to Environmental Stresses, are looking at a way to genetically modify soybeans to prevent damage from aphids. If the research is successful, soybeans will carry in-plant protection from aphids, similar to the way genetically...

Using pathogen genomics, Professor Paul Birch from the Division of Plant Sciences, University of Dundee (at Scottish Crop Research Institute - SCRI), alongside researchers from Warwick HRI and the University of Aberdeen, is looking at how the most significant potato pathogen, Phytopthora infestans causes disease and identifying essential pathogen virulence genes that may be durable targets for host resistance proteins.Costs associated with crop losses and chemical control of blight exceed...

Major crop loss may result from an explosive fungus that destroys tomato plants and is rampant in the Northeast, federal agriculture officials said Friday. Late blight, a highly contagious fungus, can jump from tomato to potato plants and caused the Irish potato famine in the 19th century. Its spores are common in soil and small outbreaks are familiar to farmers, but the cool, wet weather in June added to the aggression of the pathogen, Martin A. Draper, a senior plant pathologist at the U.S....

The disease blamed for the Irish potato famine in the 1840s is infecting tomato and potato plants in the eastern United States, agricultural officials said. A press release from Cornell University, New York state's land grant college, warned home gardeners and commercial farmers that late blight is killing the tomato and potato plants. Meg McGrath, associate professor of plant pathology and plant-microbe biology said late blight has never occurred this early and this widespread in the U.S....

Soybean Cyst Nematode, Heterodera glycines
2014-01-12 00:00:00

The soybean cyst nematode (Heterodera glycines) is a parasitic worm that infects soybean plants, and other legumes, across the world. It is thought to be native to Asia, but was found in the United States in 1954 and in Colombia in the 1980’s. It can be found in Italy and Iran and its most recent sightings have occurred in Brazil and Argentina, two major areas where soybeans are grown. These worms are highly damaging to American soybean crops, costing the industry as much as 500 thousand...
