RUST FORECASTS

  • USDA SBR Forecast 6/27/2006: Some heavy rains over the Carolinas from disturbance that came in from the Atlantic. Southern states from Texas to Alabama will remain dry while GA, FL and the Carolinas will continue to have showers.
  • NAPDFC forecast 6/26/2006: Transport events from known sources pose little threat to other areas. Rain in Carolinas, GA, FL. Localized rust development at sources is a concern. Low risk to susceptible plants Mon-Tues. New forecast due out later today (6/28).
  • The National Hurricane Center reports gale force winds over the Chesapeake Bay as the center of a low-pressure system moved across the bay. The low will spread locally heavy rains and strong, gusty winds through the Mid-Atlantic states and into New England. In addition, a large tropical wave is located about 375 miles east of the Southern Windward islands. This system is poorly organized, but is expected to bring briefly heavy rains and gusty winds to the Windward islands today. Development of this system -- if any -- is expected to be slow.

    NEW THIS WEEK

    ALERT: Soybean rust on GA kudzu called new infection in old site
    Georgia officials found rust growing on kudzu in Brooks County in same location where infected plants were confirmed and destroyed this winter, so they're calling this a new infection. Tropical Storm Alberto is possible culprit. Rust is also spreading within Georgia's Miller County kudzu site.
    Full story.

    Quick state updates:
  • Florida: New hotline set up for FL soybean rust updates, with nationwide toll-free number: 866-361-9942. FL officials say rust is sporulating and expanding in the infected kudzu sites as considerable fog and dew persist; canopy is fully developed and flowering. Still, overall rust-spore production "still very low due to our previously dry conditions."

  • Tennessee: No soybean rust, but some soybeans are dying from Phytophthora root and stem rot. Seems to be causing most damage this season at the late seedling stage up to the blooming stage, with flooding or continuous wet, rainy weather providing the conditions necessary for disease development. TN commentary links to photos, seed-treatment recommendations.
