Plant pathologists: Rust disease impacting ornamental plant production

18.02.2004


An increase in the spread of rust diseases could have devastating results on the fast-growing ornamental crop industry, say pathologists with The American Phytopathological Society (APS).



The U.S. ornamental plant industry, which includes deciduous and evergreen trees, shrubs, cut flowers, and foliage and flowering potted plants, grew in value to $14.3 billion in 2002. Geranium, chrysanthemum, gladiolus, and daylily are just a few of the many crops produced in the U.S.

According to Dr. James W. Buck, assistant plant pathology professor at the University of Georgia, a fungal infection called rust has the ability to negatively affect production of many ornamental crops. "Because live plants are shipped all over the country, the risk for rapid disease spread is substantial," said Buck. While rust fungi do not usually kill infected plants, infection by rusts will reduce plant health and flower production.


Currently, more than 125 species of fungi that cause rust have been reported on 56 different ornamental crops. "Rust pathogens cannot be adequately detected on contaminated but symptomless plant material entering the U.S. or moving state-to-state," said Buck. "As such, rust pathogens have the potential to dramatically affect ornamental crop production," he said.

Rust spores can easily lodge in the crown of plants that have had foliage removed for shipping purposes. Symptomless plants are then moved long distances through international or interstate trade, dispersing the pathogen and introducing it into areas that were previously pathogen-free.

While quarantine restrictions and eradication efforts are used to manage rust outbreaks and minimize potential disease loss, such efforts are not perfect and can have a significant economic impact on crop production. International trade of ornamental crops has made the exclusion of rust pathogens difficult because contaminated plant parts may be symptomless and inadvertently allowed to enter quarantined areas. With repeated introductions, pathogens may become widespread and cause the quarantine to fail.

According to Buck, plant pathologists are currently working on improved detection methods and developing new diagnostic methods to quickly and accurately identify quarantined pathogens.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
