Soybean Rust Information
A toll free hotline has been established for producers and others to call
for up-to-date information about the possible spread of Asian soybean rust
to Tennessee. The number is 877-875-BEAN (877-875-2326).

On Friday, September 4th, soybean rust was confirmed on soybean leaf samples collected from several Shelby county field locations. On Wednesday, September 16th two positive counties, Tipton and Coffee, were confirmed, and on, Monday, September 21st, three more counties were confirmed, McNairy, Hardeman and Fayette. This brings Tennessee to a total of 6 counties positive for soybean rust during 2009.

Soybean Rust Reported in Tennessee
posted 8-24-09
On Friday, Saturday and Sunday (August 21-23) soybean rust was detected at low levels in commercial soybeans in Quitman, Tallahatchie, Calhoun, and Coahoma counties of Mississippi on soybeans in the R7-R8 growth stages.
Posted 8-11-09
This report can be found at the web site: www.sbr.ipmpipe.org. There was
one other find in Holmes Co. MS. Both of these finds are at very low
levels and the Extension Plant Pathologists in those states are not even
recommending any rust prevention sprays at this time. These two counties
are very close together, one on one side of the Mississippi river and the other on
the other side.
So, for Tennessee, we are not recommending any rust fungicide spraying at this
time. We are continuing to monitor the rust movement and will let you know
should any thing develop that would concern us in TN. You may also keep up
with the rust recommendations on the telephone soybean rust hot line
(1-877-875-2326) for Tennessee.
Producers should just continue with their normal plans for spraying their
soybeans for late season diseases. It would take about 30 days of
favorable wet weather after a rust spore shower before rust could be found
in the field.

On July 23rd, soybean rust was found in Alachua County in central Florida on kudzu. On July 21st, soybean rust was reported on kudzu from Escambia County in far west Florida. This site has been positive in previous years. On July 20th, soybean rust was reported from Avoyelles Parish, Louisiana on soybean. On July 10th, soybean rust was reported on kudzu in Columbia County, Florida. Soybean rust scouting continues in the U.S. and Mexico. In 2009, soybean rust has been found in five states and 31 counties in United States, and in two states and five municipalities in Mexico.

Soybean rust has been found in a soybean sentinel plot maintained by agricultural consultant Blaine Viator in the upper portion of Iberia Parish near Coteau, LA. Blaine found it late on 6-04-09. The significance is that this is the first sighting of soybean rust on soybeans in Louisiana during 2009. The variety is unknown at this point but the crop is in the R4 growth stage. Incidence and severity are low currently. Confirmation was done in the field by Patricia Bollich using the Envirologics Quick-stix test.
Monitoring for soybean rust has occurred during all of 2009 with the pathogen being observed just after the beginning of the year on kudzu. Several sites have retained rust on the kudzu during the year, especially the site at New Iberia. At the “apartment” site, the rust has developed to a much greater degree (possibly thousands of times greater) than in past years and is producing urediospores from late winter to the present. Weather conditions have been favorable for development and spread. Scouting, especially in southern and central Louisiana and in southern Mississippi, is advised. Consult the SBR forecast (green rectangular button on the right) on the ipmPIPE SBR public site: http://sbr.ipmpipe.org/cgi-bin/sbr/public.cgi.

Soybean Rust Update
Source: The Gleaner (Kentucky)
The US soybean rust distribution map looks significantly different
from a year ago [2008], said a plant pathologist in the University of
Kentucky College of Agriculture. For the 1st time, soybean rust has
overwintered on kudzu without any break in detection in Alabama,
Georgia, and Louisiana.
This is an important development for 2 key reasons. First, infected
kudzu could serve as a springboard for movement of soybean rust to
soybeans under the right weather conditions.
Also, it is very common for storm systems to originate in the central
Gulf area. These storms commonly blow up the Mississippi River Valley
and into Kentucky. When there is significant disease activity in the
central Deep South, spores of the rust fungus commonly move in high
numbers across a broad span of northern production areas.
If this occurs early enough in the growing season, serious crop
damage could ensue. Only time will tell what, if any, effects the
overwintering has on soybean rust distribution or the 2009 soybean
crop.

Asian soybean rust found in kudzu in 5 La. parishes
Asian soybean rust has been found in Louisiana kudzu in Washington, East Baton Rouge, Tangipahoa, Iberia and St. Mary parishes, but weather conditions will be the telling factor for the disease outlook in 2009, according to LSU AgCenter plant pathologist Dr. Boyd Padgett.
