’Biofumigants’ to help beat the wilt

15.09.2003


Poor farmers in developing countries could soon be using a range of ’biofumigant’ plants to help increase tropical vegetable yields.



CSIRO is part of a research team from Australia and the Philippines which has found that brassica species such as radish, mustard or broccoli can be used to help reduce yield losses from Bacterial Wilt - the major pathogen of vegetables in tropical farming.

"Brassicas contain compounds that suppress pests and pathogens, principally isothiocyanates (ITCs)," says CSIRO Plant Industry researcher, Dr John Kirkegaard.


"When ITCs are released by manuring, soil-borne pests and pathogens are suppressed and yields of solanaceous vegetables such as potatoes, tomatoes and eggplants can be increased by up to 40 per cent. The effect is known as ’biofumigation’."

The project has already evaluated brassica species and management techniques with the aim of maximising the biofumigant effect. Current field trials in the Philippines and in North Queensland are examining ways of making biofumigation practical and effective for developing countries.

Using brassicas to manage soil-borne pests is not new - there are many previous reports of disease suppression - but new insights and techniques to measure the processes involved in the release of chemicals in soil has provided opportunities to enhance the reliability of the effect.

"The project builds on that research and is making it practical for small-scale farmers around the world," Dr Kirkegaard says.

"There are economic and social benefits for small-scale farmers, as improved crop yields lead to increased incomes. There are also a range of environmental and health benefits, as a result of reduced reliance on toxic fumigants and synthetic pesticides.

"The next stage of the project seeks farmer involvement to integrate biofumigation into the cropping system, using farming networks throughout South-East Asia and the Pacific."

The team includes researchers from CSIRO Plant Industry, the Queensland Department of Primary Industry and the Philippines National Crop Protection Centre. The project is funded by the Australian Centre for International Agricultural Research (ACIAR).

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.
