This is one of the critical steps for controlling red thread in lawns. Mow your grass short at least once a week and more often when needed. This will open the grass up to air circulation, allowing it to breathe better and help prevent disease pressure.

Taller grass has more shade and dense growth, which are necessary for red thread to live and have an excellent environment to spread.

How To Protect Your Lawn From Red Thread

The fungus that infects the turf lives in the thatch and soil and can be spread by dead infected plant material and by mowing and other mechanical maintenance. Be sure to clean your lawnmower after cutting your grass to decrease the chances of spreading the disease.

Fungicide applications are usually not necessary in dealing with red thread. The basic treatment for red thread is to fertilize the lawn with the proper amount of nitrogen as part of an ongoing feeding program.

A fertilizer application will often help your turf outgrow the damage and protect it from other potential diseases. But keep this in mind, some turf diseases are aggravated by excessive fertilization, so be sure to have an expert diagnose which disease your lawn is facing before fertilizing begins.

Treating Red Thread Disease

To control the spread of red thread disease and get your lawn looking beautiful and lush again, youll have to treat it with a fungicide. There are several fungicides on the market that prevent the spread of the disease for up to four weeks. You will need to choose a broad-spectrum fungicide that will kill the existing fungus while preventing the spread of red thread disease to other parts of the lawn.

If you can, use the fungicide product when the temperature outside is between 60 and 75 degrees F. Most lawn diseases are going to leave some damaged areas behind and red thread disease is no exception. If you have treated your lawn with fungicide and still have some damaged areas, you will likely need to patch them. Once you have the disease under control and stop seeing red tips on the blades of grass, you can reseed the damaged areas.

With the right care, youll make it harder for red thread to move in and affect your lawn.

One of the more common late spring to early summer diseases on cool-season grasses is Red Thread lawn disease. It is most severe on Kentucky Bluegrass, Perennial Ryegrass and Tall Fescue. There is another lawn disease that occurs at the same time and under the same environmental conditions known as Pink Patch.

The main difference between the two lawn diseases are the fruiting structures. Red Thread takes its name from the red thread-like structures called sclerotia that are produced by the fungus. Pink Patch produces tiny puffs of pink-cottony mycelium that resemble little bits of cotton candy stuck to the grass blades. Of the two diseases, Red Thread is the more common one seen in home lawns. Red Thread may develop when temperatures range from 40 to 75°F. Most grass activity occurs when temperatures range 65 to 75°F and during periods of cool, cloudy weather with long periods of evening dew.

Should I Increase Nitrogen Levels To Cure Red Thread

Its common conception that lack of nutrition or nitrogen are the main causes of Red Thread. This is not entirely true.

Although higher nitrogen levels can be used to burn out the Red Thread and disguise it, this does not cure it. Red Thread can still easily appear on well fertilised lawns.

If your lawn care company is repeatedly applying higher levels of nitrogen fertiliser to your lawn, Red Thread will typically be more difficult to remove. With correct greenkeeping skills and practices, your lawn shouldnt require high levels of nitrogen fertiliser at each visit.

Property owners often wonder what can be done to get rid of Red Thread on lawns when it shows up. The remedy is to disrupt the disease triangle so that this fungus stops growing.

Identifying Red Thread Disease

How To Treat Red Thread Lawn Disease – Brown Patch

You will usually start seeing red thread in the springtime. In the Pacific Northwest, you often see it well into winter due to the mild and wet climate in that part of the United States. If youve seen prolonged periods of wet and overcast weather, you will see an influx of red thread in your lawn unless pre-emptive measures are taken to prevent its spread. So, how do you identify red thread on your lawn?

If your grass is wet, you will notice a darker red color. A pink color is present when the grass is dry. If you are checking to see if red thread is present in your lawn, check for the red color after you have watered the lawn or in the morning when dew is present.

There are some things other than color that you can check for to make sure you are dealing with red thread. The blades of grass will look ragged compared to healthy grass. They will often look like they are dry and dying. Usually, the blades of grass will have an irregular shape to them.

You dont often see the thread-like strands until the later stages of the disease. The grass will start to exhibit brittle, antler-like strands extending to the grass leaf tips. As red thread disease progresses, you may also see a pink growth on top of the grass blades.

Positively Identify The Disease As Red Thread

Among the first lawn diseases of the growing season, red thread is extremely common in spring but can appear in fall in and winter as well. Cool, wet weather and prolonged overcast conditions create the ideal environment for it to thrive.

In addition to the pinkish-red color, lawns affected by red thread have grass blades that look ragged and seem to be dying back from the tip of the leaf. The affected grass will appear in irregularly shaped, straw-like patches that range in size from 2 inches to 3 feet in diameter.

The red, thread-like strands that may also be present appear more often in later stages of the disease. Youll notice brittle, antler-like strands extending ¼ inch or more from grass leaf tips. When grass is wet, red thread appears darker red in color when dry, it looks more pink. The best time to look for red thread is in the early morning when theres still dew on the blades. As red thread disease continues to progress, you may also see a pink, gelatinous growth on top of grass blades.

How To Get Rid Of Red Thread In Lawn

1. Proper Fertilization

As mentioned in the preventative section, proper fertilization will help your lawn resist diseases. Using fast-release fertilizer, in particular, will give your lawn the nutrients it needs to produce more healthy grass capable of fighting off the red thread fungus. However, proper application can also help eliminate the Red Thread from the lawn.

2. Watering Appropriately

Watering your lawn 4-5 days per week will keep it healthy and less likely to get infected. Deep and infrequent watering is best. Deep watering will help your lawn get the water it needs in the root zone where fungus cannot live.

Also, watering infrequently will allow the soil to dry out between watering, which also helps prevent disease.

Secondly, timely fertilizer and fungicide applications will ensure the health of your lawn throughout the entire growing season. The third component to ensure a lush lawn is keeping up with weekly maintenance, such as a regular irrigation schedule and consistent mowing.
