Southern corn rust is slowly moving north and west, into southern Nebraska, that state’s Extension educators report.
According to a report at Successful Farming, last week, Southern corn rust was detected on leaf samples from counties along the Kansas border.
The disease had been confirmed in several states south and east of Nebraska during the prior weeks and has been active in deep Southern states for several weeks.
The disease is at low incidence in those affected fields, but warm, humid conditions may favor disease development.
