  • 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 ...

  • Testing new biological plant protection products for effectiveness and practical feasibility

    A naturally occurring fungus codenamed ‘H39’ might be the long-sought biological defence against the dreaded apple scab. “This fungus has not only been tested for its ability to fight the pathogen. The new Select BioControl method was also used to immediately assess the practical feasibility of deploying it as a commercial product,” says Dr Jürgen Köhl of ...

  • 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%. ...

  • 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 ...

  • Living mulch, organic fertilizer tested on broccoli

    Cover crops provide many benefits to agricultural production systems, including soil and nutrient retention, resources and habitat for beneficial organisms, and weed suppression. In regions where short growing seasons can hinder the establishment of productive cover crops between cash crop growing periods, living mulch systems may provide vegetable crop growers with opportunities to establish ...

  • Agdia Releases New Molecular Test for Avocado Sunblotch Viroid

    Agdia, Inc. (Elkhart, IN) has commercialized a Nucleic Acid Hybridization Assay for Avocado sunblotch viroid (ASBVd). ASBVd is found in avocado growing regions worldwide.  Trees that are infected with ASBVd can result in a loss of yield and / or production of unmarketable fruit.  However, symptoms are not always present making pro-active testing a critical disease control ...

  • European trees planted in China to identify potentially invasive species in our forests

    Most of the exotic species which attack plants in Europe now come from Asia. INRA scientists, together with teams from the Academy of Sciences in Beijing and the Forestry University in Zhejiang have devised a new method for detecting potential invaders in their region of origin before they are introduced on another continent. European sentinel trees were planted in China for four years, and ...

  • 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 ...

  • Saving wheat crops worldwide

    In a paper published in the prestigious journal Science, scientists from CSIRO Plant Industry, the University of Zurich and the International Maize and Wheat Improvement Center have identified a wheat gene sequence which provides protection against leaf rust, stripe rust and powdery mildew. “Genetic disease resistance is highly desirable in plants as it is more environmentally friendly and ...

  • Combatting diseases in the greenhouse before they become visible

    A camera that maps photosynthesis, a DNA test that can measure the slightest traces of pathogens, or a precision spray system that only affects the plant and not the surrounding air… The Gezonde Kas (‘healthy greenhouse’) project has, over the last four years, allowed for the development of a sophisticated system of monitoring and disease control. It is now ready for practical ...

  • Marrone Bio Innovations Files Patent for a Unique Bacillus Species

    Marrone Bio Innovations, Inc. (MBI) a leading global provider of natural pest management products for the agricultural and water treatment markets, announces the submission of a patent application encompassing a new Bacillus sp. strain F727, to the United States Patent and Trademark Office.

  • 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. ...

  • Composting of biological waste

    A composting plant based on new technology has been built in Savonlinna, in Finland, and came into operation at the beginning of this year. The technology was supplied by the Finnish company Vimelco Oy. The owner, Konepalvelu Suomalainen Oy, composts separately organic waste collected from the Savonlinna area, and organic waste from the food industry. In addition the nearby local authorities ...


  • Leading New Zealand greenhouse operator chooses Hanovia UV to disinfect cultivation water

    Hanovia UV technology has been selected by NZ Hothouse, a leading New Zealand provider of fresh produce, to disinfect the water used for soil-less plant cultivation in its glasshouses. Located near Auckland, NZ Hothouse has almost 20 hectares of glasshouses on two sites growing tomatoes, capsicums and cucumbers for distribution both nationally and internationally. The source of the water ...

  • Syngenta launches new biological seed treatment

  • Changes in species interaction provide clues to climate change extinctions

    How does climate change cause extinction? An extensive analysis of the available evidence has explored this question and concluded that climate change’s effects on the interactions between species is likely to be the main reason for local extinctions. For example, climate change may lead to the loss of prey for predators. Currently, there is much evidence to show that species ...

  • International seminar on Xylella fastidiosa
