  • Creating Better Soybeans

    In rows of petri dishes, soybean roots bathe in fluorescent light, an unremarkable site unless you work in the laboratory where they grow. The simplicity of the setup belies the complexity of the research that went into creating the roots. For decades, the genes of the seeds that produced these roots have been tinkered with to create a plant that resists a common and highly destructive soybean ...

  • Biodiversity is the basis for Integrated Pest Management

    Integrated Pest Management (IPM) is now the norm in agriculture and horticulture. All stakeholders – national and European government agencies and public bodies, agriculture and horticulture organisations, businesses, universities and research institutes – agree with this statement. "More biodiversity and the use of resistant plants are crucial to the successful implementation of ...

  • The problem expands for avocado growers: 9 beetle species carry deadly fungus

    Many people love their avocados – not to mention guacamole dip. So it was bad enough when scientists said a beetle was ravaging avocado trees in South Florida. Then scientists found out that the redbay ambrosia beetle — originally determined to transmit laurel wilt — is rare in avocado groves but that six other beetle species could carry the laurel wilt pathogen. That’s ...

  • Dealing with difficult powdery mildew infections on ornamental crops

    We are now at the peak of the powdery mildew season and, with increasing temperatures and dry weather conditions, susceptible crops are likely to be at high risk of infection. The pathogen There are five different powdery mildew species which attack ornamental crops in the UK. Erysiphe ssp. – this pathogen is mainly ...

  • 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 ...

  • Syngenta launches new biological seed treatment

    Syngenta today announced the launch of the EPIVIO brand family, a range of new biostimulants which address abiotic stresses through seed treatment. Over the last five years Syngenta has developed abiotic stress management testing capabilities to simulate drought, heat, cold and nutrient stresses. Seed treatment products resulting from this R&D platform are now commercialized under 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 ...

  • UF/IFAS scientists find way to reduce pesticide use and save millions for ornamental industry

    Results of new University of Florida Institute of Food and Agricultural Sciences research may help control some dangerous species of fungi, known as phytophthora — or water molds —  that can cause millions of dollars in damage annually to ornamental plants and some fruit trees. This finding could help reduce fungicide use to control the phytophthora that can menace ...

  • 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. ...

  • Resistance genes from wild relatives of crops offer opportunities for more sustainable agriculture worldwidew

    Growing crops with stacks of two or more resistance genes from closely related species, introduced into the crop via for instance genetic engineering, combined with the simultaneous introduction of resistance management, can ensure the long-term resistance of these plants to economically significant and aggressive diseases. The combination offers opportunities to make agriculture more sustainable ...

  • Everest Visible Targeting System (Patent No. 7,355,178) Takes the Guesswork Out of Infrared Thermometry

    For some time now, infrared thermometers, such as those manufactured by Everest Interscience, have been used to measure temperatures under less-than-ideal conditions.  A major problem with infrared thermometers that frustrates the end users and prevents more widespread acceptance of infrared thermometry is the fact that the infrared measurement beam from the instrument is infrared so it is ...

  • Scientists find new defence front against the Potato Blight

    In this week 'Nature Plants', scientists from Wageningen University, The Netherlands, and The Sainsbury Laboratory in Norwich, UK, report the identification of a resistance gene that enhances resistance against potato late blight from a South American wild relative of cultivated potatoes. The gene targets elicitin, a conserved protein with an important biological function, making it less likely ...

  • Early protection, fungicide effectively reduce downy mildew in basil

    Sweet basil, a consumer favorite culinary herb, has a tough adversary. Downy mildew caused by the fungus Peronospora belbahrii has become the most devastating disease of basil plants grown in the United States. Discovered in Uganda in 1933, the first outbreak of downy mildew in the U.S. occurred in Florida in 2007. The disease has since spread to more than 30 states in the U.S., making many ...
