Rust - Cool Season Grass
Grass species affected
- Tall Fescue
- Summer through early-fall
- Rust develops during times of drought and as a result of poor fertility.
- Small, yellow specks on leaf blades and stems that develop orange or red pustules.
- Heavily infected lawns may have an orange or reddish hue and may begin to thin out.
- The “rust” will be visible on mowers and shoes.
- Maintain a regular fertilization schedule, as rust typically occurs as a result of nitrogen deficiency.
- Mow unaffected areas first and diseased areas last to avoid infecting healthy lawn.
- Collect and dispose of grass clippings in the garbage when rust is present.
- To avoid spreading the fungus, after mowing, clean the mower blades by rising with water and drying with a cloth.
- Water deeply and infrequently early in the day to allow the leaf blades to dry off and not remain wet for long periods of time.
