Fusarium patch is a fungal disease that occurs on grass.
Golf courses are very favourable environment to fusarium development, as greens are usually well watered, sheltered by trees, will high-level of nitrogen and rather alkaline soil.
Other cultural controls are possible, such as the use of resistant varieties, using soil bacteria to improve soil, practices to reduce thatch, improve drainage, mowing and raking infected patches to dry them.

The tan, to yellow, to bronze patches are often larger (a few inches to several feet in diameter) than that of Fusarium patch and appear in a variety of forms such as concentric rings, crescent shapes, or frog eyes (green turf in the center of the patch).

Brown patch is a disease caused by a common soil fungus that attacks all cool season grasses.
Because the brown patch fungus is an excellent saprophyte, the pathogen will always exist in the turf/soil environment, and the disease will be an annual threat when turf is vulnerable to infection and favorable weather conditions prevail.
Patch disease often occurs in mature stands of turf that are three or more years old, but occasionally affect younger stands.

Microdochium patch is also called Fusarium patch as well as pink snow mold in areas that receive snowfall; the fungus can attack turf underneath the snow cover, causing considerable damage if fungicides are not applied before snowfall.
If Microdochium patch has been a problem in previous years, apply a fungicide in fall before symptoms develop.
In areas where Microdochium patch is chronic, apply fungicides before the advent of cool, wet weather (late fall to early spring), and continue applications until the environmental conditions no longer favor pathogen development.
