  • Plants host pathogenic bacteria from livestock farming

    Disease-causing bacteria resulting from livestock farming can contaminate food products and find their way to humans. This occurs remarkably effectively via plants, which explains why recent outbreaks due to infection with EHEC and other E. coli and Salmonella strains are regularly attributed to the consumption of fresh vegetables. These are the findings of researchers from Wageningen UR ...

  • Desert bacteria could help boost crop yields

    Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study.   Scientists from the United Arab Emirates [UAE] have isolated local salt- and drought-tolerant strains of Rhizobia, soil bacteria that fix nitrogen when they become established ...

  • Xylella bacteria increasingly affecting olive trees in Southern Europe

    EU-wide emergency measures came into force on 19 May to deal with the bacterium Xylella fastidiosa, the cause of a devastating disease in various plants including olive trees in Italy. Xylella fastidiosa is a quarantine organism in the EU. There are no pesticides for combating this bacterial disease, so reliable detection and diagnostic methods are essential for preventing the spread of the ...

  • Controlling resilient plant viruses with steam

    Combining steam with heat-producing chemicals could control pathogenic viruses in soil, finds new research. The study examined how effective different forms of heat sterilisation of soil were at inactivating three plant viruses. While steam alone was enough to eradicate two of the viruses, the highly resilient tobacco mosaic virus required the addition of exothermic chemicals to reduce it by 97%. ...

  • Bio gas plants. More efficiency using the QZ.

    The production of bio gas from bio mass has become an important branch. Such bio mass consists of renewable raw materials or substrates from field fruit such as, for example, corn, potatoes, beets, carrots, onions, cereals, sun flowers or green offcuts. By using the Querstromzerspaner QZ, the objective of producing energy in the form of methane gas can be pursued in a more forceful way. The ...

  • Plant diversity: the secret to more nitrogen and carbon in soil

    Plants play a key role in soil carbon (C) and nitrogen (N) accumulation. New research suggests that plant diversity may have an important role to play in stimulating C and N storage in some soils. The findings suggest ways to improve carbon sequestration in grasslands and increase biomass production, for example for biofuel crops on nitrogen limited soils. Soil could be an important carbon sink ...

  • FAO launches new standards for plant genebanks

    A new FAO publication is aimed at improving conservation of food crops, many of which are crucial to the world’s food and nutrition security.  The publication, Genebank Standards for Plant Genetic Resources for Food and Agriculture, outlines voluntary, international standards for the many repositories – ...

  • New test can detect plant viruses faster, cheaper

    A new test could save time and money diagnosing plant viruses, some of which can destroy millions of dollars in crops each year in Florida, says a University of Florida Institute of Food and Agricultural Sciences researcher. In a newly published study, Jane Polston, a UF/IFAS plant pathology professor, examined several ways to detect the DNA genome of begomoviruses. These viruses have emerged ...

  • Keeping plant pests and diseases at bay: experts focus on global measures

    How to prevent insects, bacteria, viruses and weeds from infesting fruit, vegetable and other plant and food consignments and then spreading across the world is the focus of a four-day gathering of international experts which began at FAO today. The annual meeting of the Commission on Phytosanitary Measures (CPM), the ...

  • Some but not all plants can defend themselves against disease on saline soil

    Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

  • How to prevent the Xanthomonas bacterium from spreading

    Growers of strawberries and strawberry planting material are terrified of the quarantine organism Xanthomonas fragariae. If the bacterium is found, the affected parcel of land has to be partially or even fully cleared. Commissioned by trade association Plantum and the Strawberry Research Foundation, Wageningen UR performed research into how the pathogen is spread in order to prevent spreading. ...

  • Southern soils mitigate manure microbes

    That swine manure sprayed on to fields adds valuable nutrients to the soil is well known. But what is not known is whether all that manure is bringing harmful bacteria with it. A new study looks at the levels of nutrients and bacteria in soils of fields that have been sprayed with manure for fifteen years or more. The research team, composed of scientists from the USDA-ARS Crop Science Research ...

  • Actinomyces & Actinomycosis Exposed in New Online Video

    Today, the IAQ Video Network and Cochrane & Associates announced the release of another online video to help educate the public about issues that may impact their health.  The latest educational video discusses Actinomyces and actinomycosis.   Actinomyces are a Gram-positive anaerobic type of bacteria.  At one time, due to their ...

  • Wageningen UR Greenhouse Horticulture will test disinfection equipment and substances

    Starting this autumn it is possible to test disinfection equipment for pathogen elimination in soilless cropping methods. It is also possible to test substances or products to eliminate pathogens from the nutrient solution and to clean the piping. The last group can also be tested for remnants which may be able to damage plants. According a strict protocol pathogenic bacteria, fungi or virus will ...

  • USDA Seeks Public Review and Comment on Draft Environmental Impact Statement for Herbicide-Resistant Corn and Soybeans

    The U.S. Department of Agriculture's (USDA's) Animal and Plant Health Inspection Service (APHIS) released on Friday 3 2014 its Draft Environmental Impact Statement (DEIS) as part of its review to determine whether to deregulate genetically engineered (GE) corn and soybean plants that are resistant to several herbicides, including one known as 2,4-D. APHIS is performing an assessment of these GE ...

  • Nitrogen fixation helps double some African farm yields

    A large-scale research and development project has shown that giving farmers resources and advice on nitrogen fixation through legume plants can double yields and boost incomes in Africa. But not all farmers are benefiting from this practice due to a lack of access to inputs, such as fertilisers says Ken Giller, the leader of the ...

  • Antibiotic-eating bug unearthed in soil

    It’s well known how bacteria exposed to antibiotics for long periods will find ways to resist the drugs—by quickly pumping them out of their cells, for instance, or modifying the compounds so they’re no longer toxic. Now new research has uncovered another possible mechanism of antibiotic “resistance” in soil. In a paper publishing this week in the Journal of ...
