Lawn Grass Diseases as listed below.
People can face a number of lawn problems, most of which include the decoloring of the lush green vegetation. Mostly all the lawn problems are a result of pathogenic fungi that badly affects the blades of the grass, stems of the plant and their underlying roots.
Below are some of the common lawn diseases that are frequently found next to your block or may be in your very own lawn. You must give them an eye full of concern and try to figure it out.
1. Lawn Fungal Disease
Lawns are full on fungi and spores which are naturally growing vegetation and are not easy to control down. Some environmental conditions boost up the formation of these unwanted materials in the grass lawns and they need to be terminated for healthy grass growth. 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.
7. Pythium Blight
Pythium pathogen of this disease is highly affecting and can attack many types of grasses. In this diseases the pathogens affects by creating small blackened leafs and blades first of all they turn reddish brown then they turn flat and appear like greasy , roots might get brown and in severe conditions masses of fungus may appear and plant may appear as like dead.
8. Rhizoctonia blight
Its pathogen is rhizoctonia and it can affect ryegrass, bluegrass, annual bluegrass, fescues and some others. In this very type of disease the pathogen attacks and makes grass go in irregular small brown patches that don’t confine to a regular shape ,these rings can enlarge to much larger shapes many feet in diameter , leave might become water soaked apparently, and turn light brown in nature and then it can eventually die . The roots of the plant don’t get affected and sometimes the plant can even survive the attack of this pathogen.
9. Red Thread
In red thread disease the pathogen Laetisaria fuciformis attacks the grasses like bentgrasses and Bermuda grasses and in turn can make it go dyeing. Red thread kills the patches of the grass and can kill it in considerably large diameter; this disease may occur in large areas too and can leave the plant without killing it and giving it any harm. It binds the leaves together in pink bundles; the leaves might look and appear to be pink. Fungal ctusts that are gelatinous in nature can be helpful in identifying the disease.
CURE : Soil should be loosened and aerated in order to reduce the harm of this disease to the lawn, proper usage of fertilizer should be accounted , timely mowing of the land is necessary and healthy organic fertilizers should be tested and best suitable fertilizer for your lawn makes your lawn free from lawn fungal disease. More of above you should try out some suitable fungicides which are specifically engineered for the natural killing and termination of fungus from your grassy land, proper air circulation also enhances its capability to get rid of fungus.
