High humidity, moisture, stress conditions and certain types of grass can create favorable conditions for many types of lawn fungus. The professional lawn care experts at SavaLawn, the lawn care division of SavATree, can work with you to develop a specialized lawn care program that can help reduce lawn fungus. When lawn fungus diseases are suspected or present, identification of the type of fungus is crucial in order to develop a treatment plan that will return your landscape to good health. Depending on the type of lawn fungus, your lawn care specialist and arborist can develop a preventative program that includes suggestions for improving drainage, recommended mowing heights, irrigation settings and fungicide applications or specific lawn fertilizers.
Some common types of lawn fungus include:
Dollar spot is most common on bluegrass, but it affects all cool season turf grasses. It is caused by a type of grass fungus called sclerotinia homoeocarpa. Environmental conditions favoring dollar spot lawn disease are warm days and cool-warm nights with high humidity or prolonged dew. While a professional lawn care expert can best diagnose dollar spot, early symptoms are small yellow spots on blades of grass which expand to develop a straw colored band on the blade of grass. If dollar spot does not receive treatment, it can cause spots of straw-colored turf in your landscape. It can generally be thought of as a summer lawn disease, occurring primarily from June to September.
Powdery mildew grass fungus can begin growing as soon as the grass starts to grow early in the spring. Damp, shady areas of your lawn are more susceptible to this type of lawn fungus. Your lawn care professional may recommend improving drainage, air circulation or reseeding with resistant varieties to help cure powdery mildew.
Summer patch, brown patch and other similar patch diseases are caused by a group of fungi that infect the grass roots and are difficult to diagnose and manage. The challenge with summer patch, brown patch and other similar patch diseases is that the symptoms often are not visible until damage has been done to the roots, so SavaLawn recommends that treatments for patch diseases be done on a preventive basis.
Symptoms normally become obvious when the lawn is under stress such as hot weather in late summer or during periods of damp weather where drainage is a problem. Patch disease infection doesn’t become obvious until the plants go into stress, normally in June or July from the summer heat and reduced rain.
Summer patch is a relatively new type of disease for our geographic region and occurs most often in Kentucky Blue Grass (especially sodded lawns), but also can occur in many other types of grass.
Newly planted, young grass is particularly susceptible to brown patch disease. Symptoms of brown patch can vary greatly and can be mistaken for other types of lawn disease including dollar spot, so a lawn care specialist is the best resource for identifying it. Brown patch can develop rapidly – sometimes within 24-28 hours — when the weather is hot or very humid. Special fungicides can be applied as a preventive measure or to treat existing brown patch disease.
