Some farmers in Turner and Lincoln County might be seeing southern rust in their corn fields.
Southern rust is a fungal pathogen that blows up from the southern states. It's most commonly found with hot temperatures like we have been seeing this August and stays with plenty of moisture. Experts say if it was a cooler August we usually wouldn't see southern rust, but more of a common rust in corn.
The rust looks circular in shape, is orange and light brown colored, and is and usually found in the upper surface of the leaves.
Experts say cooler temperatures may get rid of the rust, but there are also other things you can do if you are experiencing it in your crop.
If you have a severe amount, you could receive yield loss. But experts say they don't have the data quite yet to predict how much.
