Fungal disease attacks

Take-all Patch

Take-all Patch is a serious root disease that can affect bent grass swards that are less than eight years old. It is commonly found on golf course greens and fairways, where it can cause serious turf loss.

Take-all Patch predominantly appears in late Spring, early Summer as reddish brown or yellow coloured rings or crescent patches on pure bent grass strands. The infected area usually contains a greyish perimeter typical of a plant beginning to wilt. The infected Take-all Patch can expand anywhere from 15cm to over a metre in a year.

Symptoms of Take-all Patch become more evident after a period of hot, dry weather although it can fade with adequate moisture and higher temperatures to then reappear during drought or dry weather. Take-all Patch pathogens prefer alkaline soils, while soils high in Manganese increase plants resistance to the disease. Acidifying treatments are thought to be the most effective method in limiting Take-all Patch development as they increase Manganese where the root zone pH is less than neutral.

Fungal disease attacks

Fusarium Patch

Fusarium Patch is caused by the fungus Microdochium Nivale. This same fungus can also produce different turf symptoms on affected swards following snow melt. Under these conditions the disease is called Pink Snow Mould.

The very early symptoms of infection may go unnoticed as slightly paled patches of turf throughout the sward. As the disease begins to take hold, the first real signs of infection are small water-soaked dark brown patches, that rapidly fade to tan. The patches increase in diameter from approximately 5cms to 25cms. Dark water-soaked turf around their outer edges confirms that the disease is active.

The individual patches may join together and if left untreated the damaged turf will be killed leaving scars that may take weeks to fill in.

In extreme cases the growth of the fungus may be apparent during the early morning as a white mycelium on the surface of the turf around the edge of the damaged area.

Fusarium can be seen all year round and is created by a combination of excess thatch, high nitrogen applications, poor surface drainage and high surface Ph. Alternatively frost and thaw will encourage disease progression and high humidity, fog and drizzle will readily activate this disease.

Red Thread (Laetisaria fuciformis)

A very common fungal disease which usually indicates poor turf nutrition. It appears as unsightly straw coloured patches with vivid pink spikelets on the leaves. It rarely kills the grass. Nutrient leeching during a wet season will bring this disease to the fore and a balanced foliar feed will usually aid recovery.

Anthracnose (Colletotrichum graminicola)

Basal rot anthracnose is often triggered by plant stress. Low mowing, deficient nutrient levels, cultural practices that damage plant tissues and heavy wear all contribute to the spread of the infection. Poa Annua Greens are very susceptible during cool, wet conditions.

Infection causes rapid decline of individual plants. Turf damage may not appear until plants suffer summer stress. Crown tissues rot and turn black, making the bright yellow leaves easy to dislodge. Preventive spraying gives the best chance for fungicides to be effective. Reducing plant stress and the use of a High K foliar feed will reduce the effect and help recovery.
