What would make my grass dusty orange?

Answer by  FedEx (61)

This is called Rust. It thrives in hot and humid conditions and would cause the appearance of dusty orange patches on the blades of your grass. Rust developes due to low amounts of nitrogen in a lawn and can be treated with a fungicide. Excess rain or irrigation can cause Rust.

The orange you would be seeing is a common lawn decease called, Rust. More so on the Marion and Touchdown types of bluegrass. When you mow the lawn the little spores are thrown out into the air and then land back on the grass. The grass gets wet with dew and pools the spores into visible spots on the grass.
