  • New method may help detect avocado pathogen earlier

    University of Florida researchers have found an algorithm to help them detect laurel wilt, the deadly pathogen that threatens Florida’s $100 million-a-year avocado industry. Reza Ehsani, an associate professor of agricultural and biological engineering, said the algorithm finds laurel wilt-infected avocado trees before symptoms are visible to the naked eye. About 500 growers produce ...

  • Ambrosia beetle spreads dangerous avocado pathogen

    As the laurel wilt pathogen casts a cloud over the $100-million-a-year Florida avocado industry, University of Florida researchers continue to look for clues to prevent the pathogen from spreading. The main culprit has been the redbay ambrosia beetle, which has infected millions of native redbay and swampbay trees with the laurel wilt pathogen, but it is rarely seen in commercial avocado ...

  • 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 ...

  • Crop pests ‘vastly underestimated’ warns study

    The number of different pests plaguing crops in the developing world may be vastly underestimated, contributing to severely reduced harvests in some of the world’s most important food-producing nations, say researchers. About 200 pests and pathogens per country fly under the radar of researchers and policymakers in the developing world due to a lack of technical capacity to detect them, ...

  • 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 ...

  • Managing Late Blight of Potatoes and Tomatoes

    Late blight is one of the most serious diseases of potatoes and tomatoes worldwide, resulting in significant yield and quality losses annually. In Alberta, late blight occurs infrequently, but can have devastating impacts in the years when it reaches epidemic levels.  “This disease is caused by a fungal pathogen called Phytophthora infestans,” says Robert Spencer, ...

  • Global stem rust tracker unveiled in China

    A global monitoring system was unveiled today to track the spread of devastating wheat pathogens known as stem rusts, at the 2012 Borlaug Global Rust Initiative (BGRI) Technical Workshop in China. The functional surveillance and monitoring network, the Global Cereal Rust Monitoring System ('Rust Tracker'), now covers 27 countries and a large ...

  • 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 ...

  • USDA Announces $22 Million Available for Research to Combat Citrus Greening

    The U.S. Department of Agriculture (USDA) today announced the availability of $22 million in grants to help citrus producers fight Huanglongbing (HLB), commonly known as citrus greening disease. This funding is available through the Specialty Crop Research Initiative (SCRI) Citrus Disease Research and Extension Program (CDRE), which was authorized by the 2014 Farm Bill and is administered by ...

  • 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 ...

  • Federal government to step up bird flu monitoring this fall

    The federal government announced plans Thursday to step up monitoring wild birds for avian influenza this fall to provide an early warning of any resurgence of a disease that devastated poultry farms in the Upper Midwest. The U.S. Department of Agriculture issued a pair of plans aimed at minimizing the impacts on domestic poultry flocks if any bird flu viruses return or mutate in migrating ...
