Common Lawn Fungal Diseases
There are quite a few fungal diseases that can impact lawns, but theyre usually pretty specialized, targeting specific lawn types, at certain times of year, under certain conditions. For example:
- Brown patch strikes during hot, humid weather.
- Fusarium blight prefers hot, drought conditions.
- Dollar spot tends to spring up when nights are cool and dew is heavy.
Before treating your lawn, its important to identify not only whether your lawn indeed has a fungal disease, but to identify the fungus itself. All fungicides arent the same, and some diseases can be easily treated by making changes in your lawn care.
Knowing your grass type and recent weather conditions can make it easier to narrow down, but you may need help in figuring out exactly whats going on. Your local cooperative extension center is your best resource for determining which diseases are most common in your area, or you can take a small baggie of the infected grass to your local garden center for help.
Types Of Lawn Diseases And Fungi And How They Spread
As if it wasnât nuisance enough, there are various lawn fungus types to look out for. Many of the symptoms are similar, and weâll discuss how to tell if your lawn has fungus in the next section, but itâs important to be aware that there is more than one kind of lawn fungus or lawn disease.
One grass fungal disease will specifically target grass and leaves, while others infect the soil and prevent grass from growing. Others present themselves as dots throughout the lawn, and perhaps one of the most identifiable fungi appears as a fairy ring in turfgrass.
Fungi are spread primarily by wind and rain, but can even be spread with a lawnmower. If youâre unaware of a fungus problem on your lawn and use a lawnmower on infected parts of the grass, fungal spores can easily be spread to other parts of the land, speeding up the spread of the problem.
Youâll typically notice fungi growing in the dampest environments, so that may be under trees or in lower parts of the ground where water gathers.
The trouble with fungus is that it only presents itself once the disease has taken hold, and tackling those patches requires a good understanding of how the infection works. There are steps you can take to prevent lawn fungus problems, but it always starts with identifying symptoms.
What Is Red Thread
Red Thread is a fungal disease found on lawns and is circular or irregularly shaped with small to large patches in diameter.
The first symptom of Red Thread in turf is the tan colour of dead grass leaves.
Dead lawn leaves caused by Red Thread are generally interspersed among uninfected leaves giving an overall diffuse, scorched or ragged appearance to the patch.
Red Thread thrives in temperatures between 17°C to 29°C which are also humid.
Read Thread causes fungus primarily during periods when grass is growing slowly as a result of low temperatures, drought or inadequate fertility.

How To Prevent Lawn Fungus
Watering: Many lawn fungi develop under moist conditions. You cant control when and how much it will rain, but you can control when your sprinklers come on and turn off. Water early in the morning to allow the grass blades to dry in the sun during the day. Watering at night can lead to turf disease because the mycelia that cause the fungi are spread by the water droplets at night.
Fertilizing: Both over- and under- fertilizing can promote some fungal diseases, and synthetic fertilizers, pesticides and other lawn chemicals can upset the balance of your lawns ecosystem, allowing disease organisms to grow. Jonathan Green Organic Lawn Food 10-0-1 is great for newly seeded lawns or existing lawns. It works overtime to strengthen your lawn and give it the nutrients it needs.
Mowing: Keep the mower blades sharp and mow your lawn to the correct height. Never cut more than half of the grass leaf blade in one mowing or it can shock the plant, especially during times of heat and drought stress, and make it more vulnerable to fungal disease.

Will Fungicide Kill Grass
First of all, lets figure out what a fungus is. It is nothing more than the outdoor mushroom that can have different colors: white, yellow, brown. What are fungicides? They are the remedies that were specially designed to fight against those outdoors mushrooms. There are two types of such lawn fungicides: those that act like a treatment and those preventing the fungus appearance. In the vast majority of cases, one product combines both functions. On the other hand, organic fungicide for lawns does not use any toxic ingredients that can damage your lawn. Moreover, it contains the minerals and vitamins that nourish the lawn and make it free from various diseases and pests.

What Is The Difference Between Narrow Vs Broad
The fungicides can be specially formulated to target specific diseases or control a wide range of infections. The narrow-spectrum fungicides are usually systemic, which means the plant can safely absorb them.
The broad-spectrum fungicide is usually a contact fungicide that can indiscriminately kill a wide variety of fungi. You should choose the one depending on the type of disease you’re trying to treat.
As a general rule, you should spray the preventive fungicide on grass fungus when the environment is hot and humid. This is because, in these climatic conditions, the grass is more susceptible to fungal infection.
You should also use balanced fertilizer to keep the turf healthy and strong so that it can fight off any disease or infection.
