Common Zoysia Grass Problems
Although relatively free from most pests and diseases, zoysia grass isnt without its faults. One of the most common zoysia grass problems is the buildup of thatch, which is caused from undecomposed organic matter. This buildup forms just above the soil line.
While raking can sometimes alleviate the problem, regular mowing helps to prevent thatch from accumulating throughout the lawn. It also helps to limit the amount of fertilizer used on zoysia grass.
If you find sections of zoysia dying, this could be attributed to grub worms. Read detailed information on grub worm control here.

Rust Fungus In Zoysia
The Puccinia fungus that causes rust fungus in zoysia grass is a disorder most common in early spring and peaks again in the summer. It can be particularly hard on lawns that are stressed by drought or do not have adequate nutrients or nitrogen in the soil. Yellow spots appear on the leaves, followed several days later by raised yellowish-orange blisters of fungal growth. The leaves become discolored and wilt.
Severely infected lawns may look orange or yellow in color because of the number of fungal spore masses. Treat rust by adjusting the soil nutrient and pH levels, and mow often until the outbreak slows or stops.

Should I Water My Grass If It Has Fungus
It is important to treat the Fungus right away so that it does not spread throughout your lawn. It is recommended that you only water your lawn as much as it needs to be watered. Do not water more than once a week. Do not use chemical sprays or fertilizers to control the fungus.
Instead, use a fungicide such as Fungicide-Free Lawn Fertilizer, which is available at most garden centers and garden supply stores. This product is safe to use on lawns that have been treated with other fungicides, but it may not be effective on grass that is not treated. If you are unsure about the effectiveness of this product, contact your local garden center for more information.
Continue To Monitor For Fungal Diseases
After treating the problem, continue to monitor your turf for signs of fungal infections. Some fungal diseases are seasonal and may return the following year, requiring you to repeat the treatment. In the meantime, maintain correct mowing techniques.
If possible, collect grass clippings as you mow. Collecting clippings minimises the spread of fungal diseases, as most types of fungi are easily distributed throughout a lawn. Avoiding excess foot traffic also cuts down on the spread of fungal diseases.

Conditions Favoring Rhizoctonia Large Patch R Solani Large Patch
is a strong saprophyte, meaning it is able to survive for extended periods of time in the absence of living host plants by feeding on decaying organic matter. When conditions are not favorable for growth, the fungus persists in the thatch layer and soil. When a host plant is present and environmental conditions are favorable, the fungus begins to colonize the surface of the potential host plant .
Infection of the lower leaf sheaths by R. solani occurs whenever the temperature of the thatch layer is between 50 and 70 °F, and continuous moisture is available for at least 48 hr. Because warm season grasses are not growing vigorously during the spring and fall, they are highly susceptible to pathogen attack. Patches may also develop in the summer during periods of cool weather, especially in wet or shaded sites . Excessive moisture levels in the soil, thatch, and lower turf canopy encourage the development of large patch. Poor drainage, shade, restricted air movement, or excessive irrigation increase the severity of this disease.

Causal Agent And Disease Cycle
The fungus, Rhizoctonia solani is the causal agent of large patch. This fungus and several related species are responsible for numerous turfgrass diseases that can occur at anytime on all grasses, except during very cold winters. The fungus overwinters as dormant thread-like fungal strands in infected plants or as special survival structures . The production of true spores does not occur. Therefore, spread of this fungus can occur through movement of infected plant parts or soil by equipment, people, animals, water, or wind. Epidemics are typically initiated when temperatures are mild and prolonged periods of high humidity exist. In Oklahoma, infection of susceptible grasses begins in late September when soil temperatures are above 50° F, moisture is adequate, and may continue until dormancy. Fungal activity can resume in early spring but is suppressed by soil temperatures that exceed 85° F.
Turfgrass grown under high nitrogen fertility that is applied too late in the year or very early in the spring is more prone to the development of large patch. Turfgrass that is also excessively irrigated, has abundant thatch, or poor air circulation above the canopy can be predisposed to disease. Extended periods of wet, mild weather can lead to severe epidemics. During summer months the disease subsides, patches will fill in with new grass growth, and the fungus will survive in thatch as mycelium or as resting structures.
