Identifying Rust -
Rust is a relatively easy lawn disease to identify in your lawn. It initially causes light yellow flecks on the grass blades and sheaths. The flecks enlarge and elongate over time, turning yellow in color. These areas then rupture, releasing spores that are yellowish-orange to reddish-brown in color (hence the name “Rust”).
A severe disease infection can cause the entire turfgrass shoot to turn yellowish to reddish-brown in color and slow growth in your lawn.
Turf may appear to be thin as individual shoots begin to die. Towards the end of the Rust disease infection cycle, leaves may become shredded and point downward if the infection is severe enough. Also, plants infected by rust are more susceptible to infection from other turfgrass diseases.
Conditions for Rust Infection -
Rust can only lead to an infection in your lawn if all of the following conditions are present:
1. Pathogen – Rust (Puccinia spp.)
3. Environment – Moist climates with temperatures ranging from 65-86 degrees Fahrenheit and low nitrogen soils
Cultural disease control practices create favorable conditions for a healthy lawn, and often create unfavorable conditions for the growth of Rust. Environmental conditions cannot be changed, but cultural practices performed by the homeowner can be modified to lessen the chance of extensive damage from Rust.
