Disease Control

If you notice irregular or ugly growth in your turf, you may have a lawn disease. Lawn diseases appear in spots, circles, or dry patches that range in color from yellow, brown, or red. Scenic View Landscape technicians are fully trained to diagnose and treat all common lawn diseases. We develop a treatment plan that’s right for you, and then recommend ongoing lawn services to help prevent further infection. Contact our specialist for more information today.

We Understand Lawn Care
The best way to prevent lawn disease is to maintain a healthy, vigorously growing lawn. In fact, most lawn diseases are completely preventable through proper landscaping and maintenance practices. Even when a disease-causing pathogen is present, the disease cannot spread unless the environment is favorable to disease development. Prevention is simple: routinely apply the optimal amount of water and fertilizer, and follow through with regularly scheduled mowing, aeration, and pest treatment services specific to the needs of your grass species. At Scenic View Landscape, we offer comprehensive lawn care programs to help prevent and treat all common lawn diseases.

Common Lawn Diseases in California

diseas grass dollarDollar Spot
Grasses susceptible to the Dollar Spot disease include bermudagrass, annual bluegrass, fescue, ryegrass, and more. Dollar Spot appears as small, circular spots ranging from 1–5 inches in diameter. As the disease spreads, the spots may merge to form large irregular areas. The grass leaves will appear brown and may exhibit a reddish band across the leaf. In the early morning, you may notice fine, white cobwebby threads. Dollar Spot thrives in moderate temperatures (60°–80°F), and may develop in underfed areas with excess moisture and thatch. Ensure your lawn is well fed and do not allow excessive thatch.

Fairy RingsFairy Ring
All grasses are susceptible to the Fairy Ring disease. Up to 40 different species of fungi cause Fairy Ring, making it a common disease across the United States. As the disease starts to develop, you’ll begin to notice a raised, dark-green band of grass on the turf. In the band, it’s likely that you’ll notice mushroom growth. The ring will start small, but year-after-year the size will increase in diameter. A second ring of dying grass may appear inside the circle. Fairy Ring thrives in soils high in thatch or undecomposed organic matter. Proper core aeration and fertilization are important steps in prevention and treatment.

Fusarium BlightFusarium Blight
Fusarium Blight is almost entirely preventable with proper lawn maintenance. An infected lawn will display circular, grayish-green areas that range in sizes up to a foot in diameter. Some grass may survive in the center, which creates Fusarium Blight’s recognizable frog-eye appearance. The disease thrives in temperatures between 85°–95°F. Lawns subjected to drought-stress, excessive thatch, over fertilization, and water stress are at high risk for infection. Kentucky bluegrass is most susceptible to the disease, but other grasses that may be affected include creeping red fescue, bentgrass, centipede, and bermudagrass.

red threadRed thread
Red Thread attacks Kentucky bluegrass, perennial ryegrass, and tall fescue. Red Thread infection takes place at the tip of the leaves. The infection appears in 2–8 inches circular patches that are red or tan in color. Look for pink, gelatinous fungal crusts extending from the leaves. Red Thread is common under mild air temperatures, extended periods of leaf wetness, and slow growth turf. It is also very common on plants deficient in nitrogen due to excess irrigation or rainfall. Because Red Thread doesn’t kill the root system, symptoms often clear-up in warmer and dryer weather. Keeping the lawn well-fed is the best preventative step for this disease.

rust on grassRust
Kentucky bluegrass and perennial ryegrasses are the most susceptible grasses to the Rust pathogen. Rust disease appears as irregular patches of turf covered with rust colored spores. The spores easily spread, and can show up on the soles of shoes, pets, or other objects that come in contact with the grass. Rust thrives in moderately warm air temperatures. The grass becomes increasingly susceptible to the disease in slow-growth situations such as drought, compaction, low nitrogen fertility, and shade. A well-fed and properly irrigated lawn are important steps toward prevention.

sumnmer patchSummer patch
Summer Patch commonly affects bluegrasses and fine fescues. Summer Patch is a root disease, so a maintenance routine that promotes healthy root growth is essential for prevention. Symptoms include a circular, yellow, or tan area of dead leaves that are up to 1 foot in diameter. You may notice green, healthy looking plants in the center.
