Disease Control for Lawns

Emerald Lawn Care – Your Disease Control for Lawns Experts

Lawn Diseases are caused by various fungal pathogens. They can quickly ruin your lawn’s aesthetics and, in some cases, lead to extensive and costly repairs.

To the untrained eye, it can be difficult to tell the difference between disease, insect damage, and drought stress.

Identifying what disease you have, what causes it, and how to treat it is equally difficult. Luckily, the Lawn Care Professionals at Emerald Lawn Care have the expertise and experience to eradicate any lawn disease.

Protecting Your Lawn with Emerald’s Disease Control Services.


Dollar Spot

Dollar Spot: This disease manifests as small, silver-dollar-sized spots on the grass. It typically occurs during moist, warm conditions and can be managed by maintaining proper nitrogen levels and ensuring good air circulation. Contact Emerald Lawn Care for a proper lawn maintenance program.

Gray Snow Mold

Gray Snow Mold: Active under snow cover, this disease leaves large, grayish patches as the snow melts. Prevention is mainly through reducing thatch and working with a reliable lawn care services provider.

Brown Patch

Brown Patch: This disease, characterized by large, circular brown patches, thrives in high humidity and temperatures around 80°F. Good watering practices and proper lawn fertilization from a lawn care company are key to controlling it.

Ascochyta Leaf Blight

Ascochyta Leaf Blight: This appears suddenly, causing the grass blades to turn straw-colored from the tip downwards. It often recovers naturally but can be minimized through proper watering and lawn care services.

Fairy Ring

Fairy Ring: This disease causes rings of lush, dark green grass, sometimes accompanied by mushrooms. Improving drainage and having a lawn service company aerate the soil can help manage this condition.

Leaf Spot

Leaf Spot: This disease causes small, dark-colored spots on grass blades, which can develop into thin, weak grass. Good cultural practices, like proper lawn fertilization from Emerald Lawn Care, can help manage it.

Pink Snow Mold

Pink Snow Mold: Similar to gray snow mold but with pinkish spots, this disease also thrives under snow cover. Managing thatch and avoiding excessive nitrogen in fall are preventive measures.

Snow Mold

Snow Mold: Generally referring to both gray and pink snow molds, these are cold weather diseases that appear as the snow melts. The same preventive measures apply for gray and pink snow molds.

Red Thread

Red Thread: Identified by the pink-red threads that form on the grass blade tips, this disease favors mild, moist conditions. Working with a lawn care service provider can ensure adequate nitrogen levels to help prevent outbreaks.

Summer Patch

Summer Patch: This manifests as circular patches of dying grass during hot, humid periods. It’s best managed by maintaining a healthy root system through proper watering and aeration.

Not all diseases are the same

Some are foliar pathogens that infect grass blades, while others are soil-borne pathogens that colonize the roots. Some diseases are unique to specific species of turf. Some are active in the winter months, while others are only active with nighttime temps over 80 degrees.

Regardless of the disease, three things need to exist before your lawn can become infected: The presence of the pathogen, a susceptible host, and climatic conditions conducive to disease development. These are collectively known as the “disease triangle.” Understanding this is key to controlling lawn diseases.

At Emerald Lawn Care, we make recommendations based on an Integrated Pest Management philosophy and often find that fungicides are not needed. If you can remove one leg of the “disease triangle,” you can help prevent infections before they start.

Maintaining good cultural practices is always the first step.

A healthy lawn is less likely to develop infections and is much more capable of resisting damage from infections when they do occur.

  • Lawn Irrigation: Most fungal pathogens require extended periods of leaf wetness for infection to occur. Irrigating to avoid drought stress is essential; however, when you water, it is just as important. Watering in the early mornings instead of at night will go a long way to deter infections. Watering “deeply and infrequently” (2 long soaking cycles per week) is preferable to several short cycles per week that end up causing excessive surface moisture.
  • Lawn Drainage: Maintaining good drainage and well-aerated soils and avoiding excessive thatch build-up will help ensure water moves through the soil profile instead of being held up at the surface.
  • Lawn Care: Not mowing when morning dew is present and maintaining sharp mower blades is another easy way to help prevent the spread of disease in your lawn.
  • Lawn nutrition: Maintaining proper nutrition levels and knowing what fertilizers to apply and when will help prevent infections and help your lawn recover if an infection occurs.

In cases of severe infection or with particularly aggressive pathogens, curative fungicide applications may be required to prevent unacceptable turf loss.

Did you know a healthy lawn absorbs rainfall five times more effectively than a farm field? Turf also traps dust and absorbs carbon dioxide. With a healthy lawn, you know you are contributing to a cleaner and healthier environment.
