RUST FORECASTS

RUST FLASH -- First rust of year found in Mississippi. See report below forecasts.

  • USDA SBR Forecast 8/1/2006: USDA has expanded its forecasts to include weather and rust-transport risk area predictions out 1-2 days and out 3-5 days. For today, it says "Advanced risk is expected for counties in Florida adjacent to infected areas due to typical showers and thunderstorms popping up through the period. Risk could also increase in Louisiana and southern Alabama with onshore flow from the south and coastal precipitation."
  • NAPDFC forecast 7/31/2006: Showers are expected near the sources along the Gulf coast and northern FL, but with dry weather and unfavorable transport conditions expected inland, the sources pose little long-range threat. Low risk to susceptible plants in SE Mon-Tue. New forecast due later today (8/2).
    • Tropical Weather Update
  • Tropical Storm Chris is passing over the Northern Leeward Islands, headed W/NW at 10 mph. Tropical storm warnings in place for Puerto Rico, U.S. and British Virgin Islands.

  • See our SOYBEAN RUST TRACKING CENTER for updated forecasts and tropical weather information.

    NEW THIS WEEK

  • ALERT: Mississippi reports first soybean rust in kudzu, soybeans 8/1/2006
    Both finds in Jefferson County, MS, which becomes 28th rust county in 2006 in six states. Rust was heavier on kudzu, hard to find in soybean field. Growers in SW MS with vulnerable soybeans advised to spray.
    Full story.


  • ALERT: Soybean rust found 7/27 in soybean sentinel plot in Jefferson County, Florida in north-central part of the state. Two MGVII leaves had 2-percent disease severity; another MGV leaf from the same plot was visually identified to have one pustule of rust. This is a first for the county in 2006; it was also positive in 2005.


    • Quick state rust updates:
  • Indiana: 8/1/2006 -- One rust-like spore was detected in the Jennings County spore trap in a sentinel plot last week, but officials say this doesn't mean the disease is present. Soybean rust spores cannot be distinguished from some other fungi spores under the microscope, nor can one tell if the spore is viable. "There is no reason for Indiana growers to treat fields with a fungicide for rust control at this time," officials said.

  • Missouri: 8/1/2006 -- Allen Wrather, MU Extension plant pathologist at the Delta Research Center in Portageville, says southeastern Missouri has had more normal rainfall than much of the remainder of the state, so he has elevated the soybean rust alert for southeast Missouri from very low to caution. Scouting and following rust and weather reports from southern states are recommended. The risk of soybean rust in most of Missouri is very low at this time.
