  • Soil gives away soybean pathogen’s presence

    New research reveals that soil pH is a useful guide for farmers and agronomists to detect and manage soybean cyst nematode, a devastating soybean pathogen. The investigation uncovered a relationship between high soil pH, which is already outside the ideal growing conditions for soybean, and high populations of cyst nematodes. Scientists from Iowa State University and University of ...

  • 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, ...

  • Invasive hogweed plant’s impacts decrease over time

    The damaging impacts of the invasive alien plant, giant hogweed, decline over time, new research from the Czech Republic has concluded. Although this plant initially reduces the native species richness of the grasslands it colonises, the study found that numbers of native species increased again in sites that had been colonised by hogweed for 40 years or longer. Invasive alien species are one of ...

A disease called “late blight” killed most of Ireland’s potatoes, while today it costs Florida ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Genetics not enough to increase wheat production

    The deep gene pool that has allowed wheat to achieve ever increasing gains in yield may be draining. Crop scientists estimate that 50% of the gain in wheat production over the past century has been due to breeding. According to a new study, however, that improvement has been slowing since the late 1980s, with little chance that future increases in yield can be met by breeding efforts alone. The ...

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