Managing Rust on Zoysiagrass: Cultural Practices Over Fungicides

Rust Favors Slow Growth

Rust appears in moist, low-light areas, 65–85°F. Severe on slow-growing turf with low nitrogen/water stress. Spores need 7–14 days on leaf to reproduce; frequent mowing removes infected tissue. Dry windy days + heavy dew = spread.

Best Control

Fertilize and irrigate to promote growth. Water deeply, infrequently, early day. Mow frequently, collect clippings. Fungicides (chlorothalonil, myclobutanil, propiconazole) require multiple apps—try cultural practices first. READ LABEL FOR LAWN USE.
