The fungus Pyricularia grisea causes gray leaf spot disease. The frequent warm rainy spells that occur in late spring and early summer can lead to grey leaf spot outbreaks. If left untreated, this fungus reduces turf growth, leads to bald patches, and can kill substantial areas of your lawn.

4. Anthracnose

Close mowing, poor lawn drainage, or thatch buildup are the most common causes of anthracnose. Annual bluegrass is highly sensitive to anthracnose in the spring and summer months. To prevent disease, the ideal height for your grass is around 2.5 inches.

5. Slime Mold

The majority of fungi that cause slime mold on grasses are from the genera Mucilaga or Physarum family. Slime molds are most common during prolonged periods of rainfall, which promotes fungus growth and development. Poor drainage and excessive thatch may further increase the risk of an outbreak.

6. Brown Patch

Brown patch disease is characterized by circles of dead, flat grass ranging in size from one to three feet across. The grass blades darken, wilt, and die, leaving bald patches on your lawn. Brown patch primarily affects perennial ryegrass, bentgrass, and Bermudagrass.

Hot, humid weather in the spring and fall create the ideal environment for brown patch. Weed growth can often follow to fill in the gaps.
