Which disease is commonly known as melting out?

• A. Melting out
• B. Pythium blight
• C. Brown patch
• D. Dollar spot

Answer: (A)

Melting out is the informal name turf managers use for Pythium blight. The hallmark is a rapid collapse of turf under warm, humid, wet conditions, where infected leaf blades become water-soaked and slick, and patches seem to melt away as the tissue coalesces and dies. This sudden, patchy destruction sets Pythium blight apart from other common turf diseases: brown patch tends to form larger, irregular patches with a tan-brown border, while dollar spot creates small, round spots with a pale halo. The distinct, fast-spreading melt-like decay under wet conditions points to Pythium blight as the disease described by melting out.
