Rust Disease - Puccunia and Uromyces

Identification

We are more used to seeing rust on our first car than our lawn! Infected turf appears generally yellow/orange.

Close examination reveals the leaves with orange fungal pustules which, when touched, disperse large numbers of uredospores.

These are very similar in appearance to the rust dust, which can be wiped from rusty metal, hence the name.
