For the second year in a row, Southern Rust hit fields in Southern Indiana. The infestation was far less than in 2016, in part to the cool weather in August. Brian Bush, with DuPont Pioneer, says, nevertheless, growers who applied fungicides are finding at harvest that it was well worth it, “Growers who made the investment and spayed fungicide to defend against Southern Rust are certainly seeing a payoff at harvest. I don’t recommend a fungicide until you scout your fields, and those who did this summer not only found Southern Rust but other diseases. This year using fungicides certainly paid off.” He added growers who did not use fungicides this year are seeing yield losses.
Bush recommended that growers take time this harvest to collect as much information as they can about the 2017 crop to help make better decision in 2018, “This harvest take the time to collect data on those test plots, population tests, and fungicide areas. This will help you formulate a plan for 2018.”
