Brown patch (Rhizoctonia) often has what appearance on infected patches?

Explanation:
Brown patch shows up with irregular patches that, when the leaf surfaces stay wet, take on a slimy, water-soaked look. That glossy, gelatinous film is the active mycelium of Rhizoctonia solani growing on the leaf blades, and it’s most evident under leaf wetness from dew or irrigation. As conditions dry, the center often turns brown while the surrounding edge may appear lighter or as a halo, but the telltale sign during moist periods is this slimy appearance. This distinguishes it from diseases that look dry, powdery, or form different ring-like patterns.
