Improper sowing of the land , extremely compacted soil which lack sufficient air voids and openings , more than needed use of the fertilizers and pesticides and extra use of water contents in a lawn can result in lawn fungal disease.

White or bright patches of grass can be considered as affected by the grass fungal disease rings of round diametric shapes can be best identified as a signal to this unwanted disease.

2. Fairy Ring

Fairy rings generally attack tall lawn grasses and originate from a pathogen known as Agrocybe spp, in this disease a dark green diametric ring which ranges from four inches to thirty feet in semi circular or circular shape moreover a more concentrated second type of the ring may also follow the preceding ring of the fairy ring disease.

3. Fusarium blight

It is a diseases which attacks the Kentucky grass and it has Fusaruim culmorium as its pathogen and it hosts the grass type Kentucky Grass. In this particular diseases the grass appears to be free from green patches in some parts of the land giving frog-eye view in some areas.

4. Gray Leaf Spot

Pyriculria grisea as pathogen of this disease , gray leaf spot disease that attacks fescues and kikuyugrass types , it’s a problem that makes the blades of the grass to get bleached in spots and at multiple locations of the grass blade also the ryegrass that develops a specific appearance of fishhook.

5. Microdochium Patch

Michrodochium pathogen attacks the bluegrass , annual bluegrass , fescues and many others . When this disease attacks a lawn small patches appear to be watersoaked and they give light brown texture of the grass. Spores that are gelatinous in nature are seen in the grass and they tend to appear whitish or bleached in nature. Consistently cool temperatures can enhance or aggravate this disease and can make it go wild. This pathogen can even find its living in dead grass residues.

6. Leaf Spots

Bipolarris pathogen can attack fescues , bluegrass ,bermudagrass and many more types elongated brownish bright spots with brown spots in central region and dark colored boundaries , roots have generally dark brown spots and appear rotten , many plants may die of it.
