Questions remain on how destructive the disease will be and how it will affect soybean production areas of the Midwest.
"Although soybean rust developed slowly in the southeastern United States in 2005, the disease has the potential to be more damaging in 2006 as the number of over-wintering spores on kudzu in Florida and other frost-free areas increase," said Layla E. Sconyers, Department of Plant Pathology, University of Georgia, Tifton, GA.
The absence of soybean rust in the Midwest during the 2005 growing season does not mean that the disease will remain confined to the Southeast in 2006. "It is difficult to determine whether soybean rust will have a significant impact on soybean production in the Midwest, since those areas have winter temperatures that are too cold for the fungus to over-winter," Sconyers said.
For soybean rust to develop in those areas, spores must be blown in from over-wintering sites in the Southeastern U.S., Central America, South America, or the Caribbean Basin. In 2005, environmental conditions were conducive for disease development due to numerous hurricanes and tropical storms, but the concentration or viability of spores may not have been great enough for disease development in the Midwest.
"Based on the knowledge gained from this year and next, we will continue to refine forecast models, warning systems, and provide management programs tailored for the producer in each soybean-producing region in the United States," Sconyers said. "With the information that has been collected to date, and the continued cooperation among state, federal, and private agencies observed in 2005, we have the potential to accomplish a tremendous amount of work in 2006," she said.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
