Dollar spot is caused by the fungal pathogen Sclerotinia homoeocarpa, in the Sclerotiniaceae family. The pathogen blights leaf tissues but does not affect turf grass roots or crowns. The disease is a common concern on golf course turf, but is rare in sports turf and professional landscapes. Disease symptoms commonly result in poor turf quality and appearance. The disease occurs from early spring through late fall, but is most active under conditions of high humidity and warm daytime temperatures 59-86 °F (15-30 °C) and cool nights in the spring, early summer and fall. The disease infects by producing a mycelium, which can be spread mechanically from one area to another.

Spring Dead Spot is usually considered to be the most serious disease of the couch grasses in temperate Australia. It gets its name from the fact that when the normal green-up of the sward takes place in spring small patches of grass remain pale straw colored and on examination are found to be dead. These dead spots range from a few centimetres up to one metre in diameter, but are most commonly in the 10 to 50cm range. Spots sometimes overlap to produce a variety of shapes, but this rarely causes difficulty in diagnosis.

Take-all patch is one of the many patch diseases that attack turfgrass. The patch diseases are root pathogens that attack the roots and crowns. The name “patch disease” comes from the symptoms which result from the disease. These diseases cause turf to die out in a circular pattern. As the patches mature, other grass or weed species may invade the patch giving it a doughnut or “frog-eye” appearance

Fairy rings are the result of certain types of fungi forming fungal threads in the soil that the turf is laid on. The most common fungus to cause fairy rings is Marasmius Oreades. The threads that form are very densely packed and normally reach down so soil depths of around 20cm although they have been known to reach up to about 40cm. The effect of these tightly packed threads on the lawn is to effectively starve the grass roots of both water and nutrients by inhibiting root growth and preventing water uptake. The resulting lack of water will effectively kill the grass in badly effected areas of the lawn and so yellow / brown patches can appear. Bare patches of soil may appear on the lawn where the grass has been dead a long time.

Brown patch is a turfgrass disease that is caused by the Rhizoctonia species fungus. This turfgrass disease is most common in mid to late summer when there are extended periods with high humidity and temperatures. Brown patch can be found in all of the cool season turfgrasses found in the United States. Brown patch is most devastating to: Bentgrass (Agrostis sp.), ryegrass (Lolium sp.), Annual bluegrass (Poa annua), and Tall fescue (Festuca arundinacea).

Pythium disease, also known as “Pythium blight,” “cottony blight,” or “grease spot,” is a highly destructive turf grass disease caused by several different Pythium species. All naturally cultivated cool-season turf grasses are susceptible to Pythium and if conditions are favorable to Pythium it can destroy a whole turf grass stand in a few days or less.[1] Pythium favors hot and very humid weather and will usually develop in low areas or swales in the turf grass.

Red Thread Disease is a fungal infection found on lawns and other turfed areas. It is caused by the corticioid fungus Laetisaria fuciformis and has two separate stages. The stage that gives the infection its name is characterised by very thin, red, needle-like strands extending from the grass blade. The other stage is visible as small, pink, cotton wool-like mycelium, found where the blades meet. It is common when both warmth and humidity are high.

This complex of diseases, often called ‘helmo’ and previously known as helminthosporium leaf, crown and root diseases, is present on all turfgrass species. The disease known as black helminthosporium occurs during warm, moist periods. It causes reddish-brown to purplish-black spots on leaves and stems, and spreads very quickly. Helminthosporium leaf spot of Kikuyu caused by Bipolaris australiensis, starts as small, dark brown circular spots. Severe infestation will lead to turf and runner death.

Anthracnose (caused by Colletotrichum cereale) is a destructive fungal disease of weakened turf that occurs throughout the United States, Canada, Western Europe and Australia (15) and is particularly severe on annual bluegrass (Poa annua). The frequency and severity of anthracnose epiphytotics on golf course putting greens has increased over the past decade (13, 14) and is thought to be associated with some of the management practices used by superintendents to improve playability (ball roll). It is possible that combinations of management factors may be enhancing the severity of this disease turf is laid on.

Kikuyu yellows is caused by the oomycete Verrucalvus flavofaciens and is the primary disease of turf and pasture types of kikuyu. The causal agent infects the root system and causes severe root rot and root and plant death. As an oomycete thepathogen thrives in the presence of high soil moisture. Disease symptoms are consistent and are expressed as a yellowing which becomes circular as the affected area expands.
