  • 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%. ...

  • 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 ...

  • UF/IFAS scientists find potential biological control for avocado-ravaging disease

    University of Florida scientists believe they’ve found what could be the first biological control strategy against laurel wilt, a disease that threatens the state’s $54 million-a-year avocado industry. Red ambrosia beetles bore holes into healthy avocado trees, bringing with them the pathogen that causes laurel wilt. Growers control the beetles that carry and spread laurel wilt by ...

  • 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 ...

  • 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 ...

  • 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 ...
