Telling the difference between Southern versus common rust in corn

In Delta Farm Press

According to Travis Faske, Extension plant pathologist with the University of Arkansas System Division of Agriculture, growers can tell the difference between Southern corn rust and common rust by the colors of the pustules.

Orange pustules, the University of Tennessee’s jersey colors, are more likely to be symptoms of Southern corn rust. University of Arkansas Razorback red pustules most likely belong to common rust.

The difference is that a fungicide application may be needed for Southern rust, but not for common rust, according to Faske. He was a speaker during the corn stop at this year’s Milan No-Till Field Day in Milan, Tenn.
