According to USDA's Asian soybean rust (SBR) website, additional cases of SBR were reported this week across the Southeast, with Alabama now leading the way in the number of cases.
SBR has now been detected in 44 of the 67 counties in Alabama. The disease has been observed in 12 new counties this week and crop watchers expect more cases to be announced soon. " There are reports that significant yield losses may result from SBR in some fields in south Alabama where fungicides were not applied. The disease has been observed in commercial fields in the north Alabama but it appears in most cases the disease will cause limited damage."
So far this year, SBR has been reported in 135 counties in the U.S. including Alabama (44), Arkansas (3), Florida (10), Georgia (20), Louisiana (6), Mississippi (43), North Carolina (1), South Carolina (2), and Texas (2); and there have been 13 reports from Mexico. "The number of reports in September indicate widespread occurrence of rust in the south that will likely result in more or less complete coverage of soybean rust throughout the south with expected increased reports in the mid south and northern states over the next few weeks," states USDA.
