Chemically-conscious gardeners use bugs to beat back the weeds

27.04.2005


Organic gardeners can control pesky weeds with the help of some common soil microbes, according to an article in the May 2005 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology.



As Robert J. Kremer of the University of Missouri explains, soil that suppresses the growth of weeds isn’t science fiction and doesn’t involve chemical fertilisers and herbicides. “Weeds have been a nuisance for gardeners since ancient times,” says Professor Kremer. “And we often rely on the convenience of herbicides to help remove them.”

Use of chemical herbicides and fertilisers can lead to contamination of the environment, as well as resistant pests. So reducing or eliminating the use of these petroleum-based products is very important.


Professor Kremer’s research shows how well-managed microbes can provide an effective, alternative means of weed control. “The community of soil microbes is vast and using fairly simple techniques we can select the segments of this community that aggressively attack weed seeds or infect weed seedlings,” explains Professor Kremer.

Simple measures such as adding organic composts and growing winter-hardy soil covers, such as vetch, increases the number of weed-stopping microbes and have been found not only to reduce the effort of weeding and the use of chemical weed killers, but to also condition many soils that are in poor shape, restoring the quality and productivity of the land.

Britain is a nation of gardeners, apparently, but I wonder if even the gardening guru Alan Titchmarsh knows all that is going on invisibly in his back yard. This issue of Microbiology Today focuses on microbes in the garden. Pick up a free copy of the magazine at the RHS Chelsea Flower Show 2005 from the Society’s stand in the Floral Marquee.

Other features in the May 2005 issue of Microbiology Today include:

· The threads that bind: symbiotic fungi in the garden (page 56)
· Bacterial and fungal diseases of garden plants (page 60)
· ‘Broken’ tulips and tulip breaking virus (page 68)
· Barbecue roulette (page 72)
· Bugs within bugs: symbiotic bacteria in garden insects (page 76)
· Home composting and its role in waste management (page 80)
· Comment: Plant pathogens on the move (page 100)

These are just some of the articles that appear, together with all the regular features and reports of Society activities.

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“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
