Common Summer Lawn Diseases and How to Prevent Them

In this article, we will explore some of the most common summer lawn diseases and discuss effective prevention measures.

1. Brown Patch Disease

Brown Patch Disease is a fungal disease that typically occurs in the summer when the weather is hot and humid. It presents as circular patches of brown or yellowing grass that can quickly spread if left untreated. The disease is caused by the fungus Rhizoctonia solani and is most common in warm-season grasses such as Bermuda, St. Augustine, and Zoysia.

Prevention: To prevent Brown Patch Disease, it is important to avoid overwatering and to water early in the morning to allow the grass to dry out during the day. Proper lawn maintenance, such as regular mowing and fertilization, can also help prevent the disease. Additionally, avoid applying nitrogen-rich fertilizers during the summer months as they can promote fungal growth.

2. Dollar Spot

Dollar Spot is another fungal disease that is common in the summer months. It is characterized by small, circular brown spots on the grass that are about the size of a silver dollar. The disease is caused by the fungus Sclerotinia homeocarpa and is most common in cool-season grasses such as Kentucky bluegrass and fescue.

Prevention: Proper watering and fertilization are essential in preventing Dollar Spot. Be sure to water deeply and infrequently, and avoid watering in the evening when the grass is more likely to stay wet overnight. Additionally, avoid overfertilizing as this can lead to weaker grass and make it more susceptible to disease.

3. Pythium Blight

Pythium Blight is a fungal disease that can quickly destroy a lawn if left untreated. It presents as irregularly shaped patches of yellowing or brown grass that can quickly spread and merge together. The disease is caused by the fungus Pythium aphanidermatum and is most common in warm, humid conditions.

Prevention: Proper watering and drainage are key in preventing Pythium Blight. Be sure to water in the morning to allow the grass to dry out during the day, and avoid watering in the evening or at night. Additionally, avoid over fertilizing and ensure proper drainage to prevent water from pooling on the lawn.

4. Summer Patch

Summer Patch is a fungal disease that typically occurs in the summer months when the soil temperature is high. It presents as circular patches of dead or dying grass that can quickly spread if left untreated. The disease is caused by the fungus Magnaporthe poae and is most common in cool-season grasses such as Kentucky bluegrass and fescue.

Prevention: Proper watering and fertilization are essential in preventing Summer Patch. Be sure to water deeply and infrequently, and avoid overfertilizing as this can lead to weaker grass and make it more susceptible to disease. Additionally, ensure proper drainage to prevent water from pooling on the lawn.

5. Rust

Rust is a fungal disease that presents as orange or brownish-red powder on the grass blades. It is most common in the summer months when the weather is warm and humid. The disease is caused by the fungus Puccinia spp. and can affect both warm-season and cool-season grasses.

Prevention: Proper watering and fertilization are essential in preventing Rust. Be sure to water deeply and infrequently, and avoid overfertilizing as this can lead to weaker grass and make it more susceptible to disease. Additionally, regular mowing and removal of grass clippings can help remove any infected grass blades and prevent the disease from spreading. Moreover, avoid watering the lawn late in the day, as this can cause the grass to stay damp for too long and encourage fungal growth.

In conclusion, maintaining a healthy lawn requires proper care and attention, especially during the summer months when disease can strike. By following the tips outlined above, you can help prevent common summer lawn diseases and keep your lawn looking lush and green all season long.
