Lawn diseases: Identification & Treatment
Start by looking carefully at the problematic and stressed areas of your lawn. Here, we will discuss the problems that you can observe and suggestions for the adjustments:-
The circular grey and dull-colored grass is the disease caused by the snowy season. This happens mostly in the regions where it snows heavily during the winter season or the fertilizers with an excessive quantity of nitrogen have been used for the lawn.
To adjust this problem you can use a leaf rake to lift the affected grass which will reduce the risk of the further spreading of the disease. You also have to keep the pH level of the soil between 6.5-6.7 to prevent the microdochium patches (snow molds) in your lawn.
Monitor your lawn for the brown patches when temperature and humidity rise. The infected lawn will have circular patches of thin light brown grass. This brown patched condition can be caused if your lawn is wet for a long time due to the rainy season, humid weather, and excessive watering. This disease is most common in extreme warm months and extreme cold months of the year.
Therefore, providing your lawn with an accurate amount of water according to variable weather conditions and nutrients is necessary. For proper water timing and quantity, you can use a tap timer that can be easily attached to the tap.
It is critically important to identify the disease type before curing your lawn. Therefore to see if your lawn is infected by fungus then look for the white cotton type strands of fungal line sealing. This type of infection is called fungal infection and usually can be seen early in the morning on your lawn. If you deeply look at the grass, it will have irregular and dull spots all over due to this disease. Normally, these spots will have dark brown borders but they can vary in different types of grass.
To treat and get rid of this disease you must avoid heavy and fast-release fertilizers in the spring season.
The dollar spots are the size of a dollar and usually 6 inches in diameter. Your lawn is expected to catch this disease more in the cold weather conditions as compared to the warm weather conditions. The infected grass will have whitish spots and red marks on it if you closely look at it. The dollar spots on the grass could be the shape of an hourglass.
The causes of this disease include; over & under fertilization, drought, grass remained wet for an extended period, and mowing while keeping blade height too low.
Therefore, to reduce the risk of the dollar spots in your lawn, you must adopt correct mowing techniques, schedule the appropriate watering, and follow the proper fertilization ways. You can also opt for the fungicides and apply them during early fall or early spring to prevent the disease.
If you notice yellowing or pale orange patches on the grass of your lawn and see the yellow stained shoes after walking in the lawn, then it means your lawn is suffering from the rust infection. Rust is a fungal lawn disease that will form in orange powder-like substance on the exterior of grass blades. Severe infections can choke out affected grass and re-emerge year after year.
Discolored patches in the lawn can be caused by other factors like dog urination, insect activity, and other diseases. To confirm a rust infection, you will need to look at grass blades closely. This disease usually appears during the late summer and lasts until the early fall because hot and dry weather conditions are highly favorable for lawn rusting.
An effective way to protect your lawn from this disease is to maintain strong and firm grass, and by taking proper care of the lawn. If your lawn will be in a healthy state, it will survive during the attack of rust and other diseases. Raking your lawn more often is necessary and useful in keeping your lawn in a good condition.
From the above-described diseases and the tips to fight these diseases, you will be able to understand that every lawn needs proper attention and care in changing weather conditions. To prevent lawn diseases, there are so many options available in the market that include; modern fungicides, organic fertilizers, organic top-dressing, organic oils, and slow-release fertilizers. Keep in mind that you must apply the recommended dose of the products to the infected lawn.
