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).

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.

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.
