Brown patch symptoms differ depending on the various maintenance practices performed on the turfgrass (mowing height, fertilizer, watering, etc.) Symptoms on turfgrasses that are wet for extended periods and are closely mowed will produce a distinctive gray-purplish bordered ring "smoke-ring" that is up to 50 cm in diameter.

Snow mold is a type of fungus and a turf disease that damages or kills grass after snow melts, typically in late winter. [1] Its damage is usually concentrated in circles three to twelve inches in diameter, although yards may have many of these circles, sometimes to the point at which it becomes hard to differentiate between different circles.
This species of grass has hard, sturdy, hollow stems that may reach 3 m (9.8 ft) in height. [4] They grow from a network of woody rhizomes and tough roots that form a sod. The roots penetrate over 3 m (9.8 ft) into the soil. [2] The leaves have sharp, serrated edges. [5] The panicle may be up to 50 cm (20 in) long and may have many branches.
The inflorescence is dense and narrow when new, spreading out and becoming diffuse, with some branches sticking straight out, with age. The base of the inflorescence is often sheathed within the top leaf, which spreads out beside it. The grass produces abundant seeds; an individual inflorescence is capable of bearing 10,000 seeds.

Biological control is the use of other organism to reduce the invader grass. This has been proven to be effective but has also ricocheted back in a negative way. Other options include using multiple approaches at the same time, for example, mowing a specific region of grass land and then using an herbicide to target the invasive.

It is a perennial grass forming stiff, hardy clumps of erect stems up to 1.2 metres (3.9 ft) in height. It grows from a network of thick rhizomes which give it a sturdy anchor in its sand substrate and allow it to spread upward as sand accumulates. These rhizomes can grow laterally by 2 metres (6 ft 7 in) in six months.
It can grow on a wider range of sediments than other species of the genus Sporobolus, and can survive inundation in salt water for longer periods of time. S. anglicus has since spread throughout northwest Europe, and (following introduction for erosion control) eastern North America.
