Quick test for plant disease

04.10.2004


A new method will detect club root far more efficiently than before. This implies less waste and higher profits in farming.



Club root disease is very harmful to cultivated crucifers, i.e. various forms of brassica, especially cabbage. In Norway and in the rest of the world, huge crops are infected by the disease each year. For the farmer, crop failure may be up to 100 percent.

"So far we have lacked a quick method of detecting club root infections in the soil. Now we are in the process of developing a method which can detect infections within a day or two," says researcher May Bente Brurberg at the Norwegian Crop Research Institute.


Undoubtedly, there is a great potential here. Various forms of cabbage constitute an entire 40 percent of the vegetable farming acreage in Norway. Additionally, you have the production of oilseeds and lettuce.

The disease is caused by the slime mould fungus Plasmodiophora brassica. Present in the soil, the fungus causes abnormal cellular growth and swollen roots. This reduces the plant’s absorption of water and the intake of nourishment, which in turn leads to smaller crops of poorer quality.

"So far it has been difficult to detect club root infections because Plasmodiophora brassica is a parasite which cannot be grown in an artificial medium," Brurberg explains. The diagnosis requires extensive greenhouse testing and it takes six to eight weeks before you have the results. A well-established method allowing the detection of infections within a day or two may prove very useful.

"The new method may also permit the evaluation of future strategies to fight club root. A continuation of the research may be to test a series of integrated and ecological measures to fight club root disease. A quick test will be of tremendous importance to such a project," Brurberg explains.

Joining the Norwegian Crop Research Institute is the Norwegian association of gardeners and a number of marked gardens producing brassica which they sell to farmers.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

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,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

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...

Im Focus: Circular RNA linked to brain function

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...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

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...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

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...
