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.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
