Fusarium Patch

Causal Agent: Microdochium nivale

Susceptible Turfgrasses: Wintergrass, Bentgrass, Fescue, Ryegrass & Kentucky Bluegrass.

Symptoms

Circular patches appear as small, water-soaked spots less than 5cm in diameter.
Patches change in colour from orange-brown to dark brown and finally to a light gray.
Spots may enlarge indefinitely, but are usually less than 20cm in diameter.
On low cut turf a halo-like “smoke ring” may appear on the outer margin of the patch. The outer ring may have a water-soaked appearance.
In very wet conditions a thin to fluffy covering of white mycelium may be seen on matted leaves.
The mycelium is white, but on exposure to sunlight induces spore production which is a pink colour.

Conditions Favouring Disease

More than 10 hours a day of foliar wetness for several consecutive days.
Cool temperatures.
Soil high in nitrogen fertility and low phosphorous and potassium.
Areas with slow growing conditions and heavy thatch.
