From a distance, rust-infected turf appears which color?

• A. Bright Yellow
• B. Dull Yellow
• C. Dark Green
• D. White

Answer: (B)

Rust is a fungal disease that disrupts chlorophyll in the leaf tissue and produces yellow-orange pustules on the blade surface. From a distance, the overall effect is a muted, dull yellow rather than a bright yellow or green. The turf loses its rich green color as photosynthesis is hindered and spores cover the surfaces, giving the area a pale, yellow cast. If you look closer, you’ll see small orange-yellow pustules on the blades, but at distance the appearance is this dull yellow.
