  • UF/IFAS Finding Could Help Farmers Stop Potato, Tomato Disease

    A University of Florida scientist has pinpointed Mexico as the origin of the pathogen that caused the 1840s Irish Potato Famine, a finding that may help researchers solve the $6 billion-a-year disease that continues to evolve and torment potato and tomato growers around the world. A disease called “late blight” killed most of Ireland’s potatoes, while today it costs Florida ...

  • Perfect storm for potato blight

    With crop values creeping up, the need to protect is becoming ever more important to growers. However, this season’s blight threat has triggered the need for tighter spray intervals – indeed five days between applications is common – which is leading to increasing demand and potentially some product shortages in the range of fungicides available to fight potato blight. ...

  • Durably resistant potatoes with wild potato genes offer 80% reduction in chemical control

    A research project into the development of potatoes with sustainable resistance against phytophthora via genetic modification with genes from wild potato varieties and good resistance management (DuRPh) has concluded with a scientific publication on the research results. The Wageningen UR scientists indicated that their approach was successful in developing potato plants which require 80% less ...

  • 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 ...
