Type: Fungal Disease

Pathogen: Puccinia spp.

Appearance: Small, orange to yellow pustules form on grass blades, giving rise to a rusted or dusty appearance are telltale signs indicative of lawn rust

Risk Factors: Lawn rust is most often found in areas with high humidity and weakened grass. Factors such as compacted soil and nutrient deficiencies contribute to your lawn’s vulnerability

Timing: This fungus thrives in warm days and cool nights, making it most prevalent during late summer and early fall.

How to Control Lawn Rust


Proactive measures are crucial in preventing and mitigating the impact of lawn rust:

  • Balanced Fertilization: Maintain proper nutrient levels through a balanced fertilization program to fortify your grass against the onslaught of lawn rust.
  • Lawn Aeration: Regularly aerate your lawn to reduce thatch and improve air circulation, creating an environment less conducive to the development of this fungus.
  • Morning Watering: Water your lawn in the morning to allow grass blades time to dry during the day, minimizing conditions favorable to lawn rust.


When this disease takes hold, effective treatment involves:

  • Fungicide Application: Apply fungicides labeled for lawn rust control during active infection periods. These targeted treatments can help arrest the progression of the disease and limit further damage.
  • Improved Nutrient Levels: Correct nutrient deficiencies through targeted fertilization, enhancing overall grass health.
