Asian soybean rust has now been confirmed on soybeans in Iberia and St. Mary Parishes in Louisiana. The finds were confirmed on Aug. 18 on soybeans in the R5 growth stage.



On Aug. 15, ASR was confirmed in two parishes, Avoyelles and Tensas, on soybeans.



On Friday, August 11, 2006, Asian soybean rust (ASR) was found in a sentinel plot of soybeans in Natchitoches Parish, La. The beans are Group Vs and are at R5 growth stage.



Harvesting has begun in many of the soybean growing areas especially with early maturing varieties or those planted early. Some late planted beans are in the early reproductive stage.



Currently rust has been found infecting this year's soybeans in 12 different counties in Alabama, Florida, Georgia, Louisiana and Mississippi. Including reports on kudzu, there is a total of 32 counties with rust this year including five in Alabama, 13 in Florida, six in Georgia, six in Louisiana, one in Mississippi, and one in Texas. Spore trapping continues throughout the U.S. using both active and passive traps. Any positive spore trap information does not imply infection has taken place and plant samples are used exclusively for recording positive rust occurrence.



Recent shower activity has been reported in some of the infected areas and local infection has increased in some cases.
