Andy Shirley, County Extension Agent in Mitchell County, found southern corn rust in a field in Mitchell County. There was not much there but it WAS there!
Dr. Bob Kemerait says, “This is the earliest find of southern corn rust in my 15 years in Georgia. Corn growers in south Georgia should be very much aware NOW that rust is here. Current weather patterns increase the risk. I believe that any irrigated field corn with good yield expectations and that is at tassel or beyond is a good candidate for treating with a fungicide. Corn approaching tassel is also certainly at risk.”
NOTE: do not mix an aduvant or crop oil with the fungicide if prior to Tassel stage.
