On
July 26, soybean rust was confirmed on soybeans from a sentinel plot in
Rapides Parish, Louisiana. This is the first report of rust on soybeans
in Louisiana for the 2006 season. So far this year, rust has been
confirmed on soybeans in six different counties in four states: Alabama,
Florida, Georgia and Louisiana. The rest of the finds have been on
Kudzu – 26 counties in five states: Alabama (5), Florida (12), Georgia
(5), Louisiana (3) and Texas (1). The movement of rust to other areas
has been slow this year due to dry to very dry weather in spore source
regions. Last year at this time, there were 14 confirmations of rust in
Florida, Georgia, Alabama and Mississippi.
