Common Corn Rust 2015

Posted by romeethredge on May 28, 2015

We are now seeing some common corn rust in our fields. It is not the bad rust that causes us yield losses. This rust is a cooler season rust that perhaps infected when we had a series of cool nights a week or so back. It causes damage on both sides of the leaf whereas southern rust is just on the leaf tops usually. This rust is darker  brick red as well in color. The bad southern rust is a more orangish color.

When you look at it under the mircoscope it is more round in shape and has thicker walls than southern rust. common rust2
