Southern Corn Rust a Danger to Untreated Arkansas Corn

August 17, 2017

Bay, AR, situated outside Jonesboro in Northeast Arkansas, experiences pressure from southern corn rust most years. This one is no exception. Under favorable weather conditions, yield loss from southern corn rust can be severe, reducing yields by as much as 25 bu/A on susceptible hybrids.

This disease prefers damp and warm field conditions. Although the beginning of the season was cooler than usual in Arkansas, it was extremely wet. When it did heat up, that moisture aided in the development of the disease, which can seriously damage the crop. The best solution is to prevent infection by applying a foliar fungicide like Trivapro®.

At our Grow More Experience site in Bay, AR, our agronomy team and visitors have been impressed by the Trivapro treated corn. The photo above demonstrates why. Corn treated with Trivapro is disease free and still green so that the leaves continue to feed the ears for maximum grain fill. The untreated corn is covered in disease and dying back, which means less grain fill.

When dealing with diseases like southern corn rust and other late-season diseases, Syngenta encourages growers to time fungicide sprays at the VT/R1 stage before late-season diseases strike. The longer-lasting residual of Trivapro will keep rust and other difficult to control diseases under control.
