With no reports of southern rust in Tennessee (only some in GA and LA reported at this time), it is a relatively quiet disease season in corn, with the exception of grey leaf spot and physioderm brown spot in Tennessee.
The UT Cotton Scout School is scheduled for the last Friday of the month, May 31st, at the West Tennessee Research and Education Center (605 Airways Blvd, Jackson). There is no fee, and preregistration is not required. Registration begins at 8:00 AM with the program starting at 8:30. Content will include classroom and hands-on training with an optional ‘go-to-the-field session’ after a box lunch. Topics covered will include cotton development and identification and symptoms of insect pests, plant diseases, and weeds.
