Don’t miss out on the opportunity to have your soil tested for parasitic nematodes and charcoal rot at no cost for Tennessee Farmers ($15 fee for out-of-state samples). Continue reading
Wondering what’s been making your soybeans sickly? Come to The University of Tennessee Soybean Disease Field Day, held Tuesday, Sept. 4th, at the Milan Research and Education Center. Registration will be from 8:30-9:00 AM with the tour beginning at 9 AM and concluding with a box lunch. Preregistration is not required. Pesticide re-certification and CCA points will be available. Field demonstrations will include soybean disease identification, UT variety trials, fungicide efficacy trials and other UT disease research trials. Hands on disease identification will cover main soybean diseases that occur in Tennessee including frogeye leaf spot, target spot, Cercospora leaf blight, southern stem canker, sudden death syndrome, and others.
Most soybeans have gotten into reproductive growth stages and diseases may have started appearing although at low levels. To better identify diseases and guide management decisions use the resources below… Continue reading
