Fighting Southern rust: A matter of timing: Part II

Travis Faske says Southern rust can move faster through the Mid-South when corn prices are low.

Dr. Faske, plant pathologist with the University of Arkansas Cooperative Extension Service, was being somewhat facetious, but not totally because growers aren’t as likely to treat for the disease with corn at $3 a bushel.

In the absence of spraying for the disease, Southern rust can move from the lower to the upper Mid-South in a matter of weeks. Dr. Faske says controlling the disease can be helped by timing applications of fungicides to the early stages.

He talked about conditions that contribute to the development of the disease and strategies for controlling it during the University of Tennessee’s Milan No-Till Field Day in Milan, Tenn.
