RUST FORECASTS

  • USDA SBR Forecast 8/21/2006: In its expanded weather and soybean rust forecast, USDA says to expect higher risks 8/22-23 into Georgia and southwest South Carolina near the front slowly pushing E into the Southeast. Also, continued flow from the east and northeast should direct spores into eastern Texas, and an increase in showers will help wash spores into new regions. For 8/24-26, the risk will stay high for neighboring counties of infected areas due to precipitation development, especially in east Texas and eastern Georgia. Winds shifting to the north should keep soybean rust from spreading toward the north.


  • NAPDFC forecast 8/21/2006: There is potential for long-range transport and deposition early this week to the north and east of the known sources. Moderate Risk 8/22 for susceptible plants in FL, southern and central GA, southern AL, southern MS, and all of LA. New forecast due out later today.


  • Tropical Weather Update: Tropical Storm Debby has formed over the far eastern Atlantic, traveling WNW away from the Cape Verde Islands at 16 mph this morning. More strengthening is forecast, says the National Hurricane Center.


    • NEW THIS WEEK

  • ALERT: First 2006 soybean rust found in SC in Calhoun County
    Asian soybean rust has been found in sentinel-plot soybeans in Calhoun County South Carolina, sample taken 8/17 and confirmed 8/21. First rust in the state this year and the farthest north rust has been found in the U.S. in 2006. There are now 35 counties in seven states that have had rust in 2006; with six states having rust on soybeans.
    Full story.


  • ALERT: Soybean rust active again on kudzu in Hernando County FL
    Two kudzu sites in Hernando County Florida were found to be positive for soybean rust on Friday, Aug. 18. The last infections in 2006 for this county were observed at the beginning of the year before the February frosts.
    Full story.


  • ALERT: Soybean rust found on kudzu in Liberty County, Texas
    Asian soybean rust was reported 8/20 at low levels on kudzu near Dayton, Texas, in Liberty County in eastern Texas. This is the first rust found in the state since rust was confirmed on late-planted soybeans harvested Feb. 14 in Hidalgo County. The same patch of kudzu hosted the first rust infection found in the state in 2005.
    Full story.


  • ALERT: New rust finds in Iberia and St. Mary parishes in Louisiana
    Asian soybean rust was confirmed 8/16 on soybeans in Iberia and St. Mary parishes in Louisiana on soybeans in the R5 growth stage. Iberia first had rust on 7/7, but the addition of St. Mary brings the LA total to seven parishes with rust in 2006.
    Full story.


    • Quick rust update
  • Georgia 8/23: Soybean and kudzu sentinel and non-sentinel sites continue to be monitored for soybean rust, with no new rust detections last week. However, with the recent rains and the detection of rust in South Carolina, it is extremely important that everyone continues to scout their soybeans for possible rust and be prepared to spray if you have not done so already. Stay tuned for spray recommendations from Bob Kemerait. Most of our soybean sentinel plots (MG-IV an MG-VI) are at the R7+ growth stage as of 8/23/06. Commercial soybeans in our state range from about R4 to R7 stages.
