Soybean rust was confirmed in Indiana on September 30th on soybean leaves collected in southeast Posey county.  The soybean field where rust was found was at R7 and rust was detected at very low levels. Pustules were observed on 14 out of 100 leaves.  Severity was low, with 1-2 pustules on each infected leaf. 

It is likely that soybean rust may be present at low levels in other areas in southern Indiana, however,  the level of disease in Indiana is very low at this time, and the vast majority of the soybean crop is past the point of economic damage occurring.
Currently there are NO spray advisories issued for soybean rust at this time in Indiana.  If there are concerns about whether or not fungicide application is warranted in specific fields (extremely late planted double-crop soybeans) please contact me at kawise@purdue.edu or by phone 765 496-2170 before applying fungicides for SBR control.
