Weather can have big impact on Southern rust: Part III

There are few absolutes when it comes to controlling diseases in corn, but there are times when  growers can make spray decisions with reasonable certainty, according to Travis Faske, Extension plant pathologist with the University of Arkansas.

Dr. Faske says one of those times may be when they find a trace amount of the orange-colored Southern rust pustules between the VT and milk stage of their corn. “If the weather is supportive for Southern rust, treat it,” he says.

Those were some of Dr. Faske’s closing thoughts during a presentation on diseases in corn at the University of Tennessee’s Milan No-Till Field Day in Milan, Tenn.
