The blades of grass are the collectors of solar power, which is turned into plant sugars or carbohydrates to fuel the growth of the sod. When the leaves are covered with spores, the photosynthetic action cannot be carried out efficiently and the fuel for good health and growth is not adequately collected.
Mow the lawn to keep it at a moderate height. Also, be sure to rinse off lawn equipment to prevent the spread of illness.

This helps decrease relative humidity and infection. An application of a fungicide may be necessary chemical If controls fail to reduce disease buildup or if the disease pressure is too great.
Many plants, like roses, vegetables and Kentucky bluegrass, have cultivars, which have been developed to be tolerant or resistant to powdery mildew. Inquire about resistant varieties. If resistant varieties are unavailable, don't plant in low locations. Once the disease becomes a problem: Avoid applications of nitrogen fertilizer to limit the production of tissue, which is susceptible to infection.
Remove and destroy all infected plant parts (leaves, etc.). For other annuals and vegetables, remove as much of its debris in the fall and the plant as possible.

An alternative nontoxic control for mould is baking soda (similar to the potassium bicarbonate listed above) combined with a lightweight horticultural oil (Sunspray). Researchers at Cornell University have found the fungicidal properties of this combination against powdery mildew on roses.
Management IPM Strategies: Cultural Practices - In locations attempts to improve air movement and reduce shading, such as shrubs and pruning trees, will help reduce disease occurrence. Choice of shade-tolerant varieties will help reduce disease incidence.
High-nitrogen fertilizers cause a dense growth of grass that makes an environment for the mildew fungus. Resistance to powdery mildew is known to exist in a number of species of fescues and bluegrass, and in several cultivars of Kentucky bluegrass, bermudagrass.
Powdery mildew occurs most commonly on the grasses such as bluegrasses and fescues, especially in shaded areas or areas with poor air flow.

Leaves are severely infected than younger leaves. Infected leaves turn yellow, then tan or brown as they die. The disease symptoms are common during fall and spring. Disease Cycle The powdery mildew fungus survives the winter months in dead grass leaves in the previous season, and in a dormant state in infected grass plants.
This is because the fungus does not need the presence of water on the leaf surface to occur. However, the air's relative humidity does have to be high for spore germination. Therefore, the disease is common in crowded plantings where air circulation is poor and in damp areas.
Print this fact sheet by S. Newman and L.P. Pottorff * (5/13) Quick Facts Powdery mildew is one of the most widespread and easily recognized plant diseases. Powdery mildews are characterized by patches or spots of white to grayish, talcum-powder-like growth. Powdery mildews are severe in dry climates. Many plants have been developed to be tolerant or resistant to powdery mildew.
Succulent growth usually is susceptible than plant tissues. About the Fungi Powdery mildews are server specific they cannot survive without the proper host plant. For example, the species Uncinula necator, which causes powdery mildew on grape and linden, does not attack lilac. Microsphaea alni impacts catalpa, elm, lilac and oak but not turfgrass.
They never invade the tissues themselves. The fungi overwinter on plant debris as mycelium or cleistothecia. In the spring, spores which are moved to host tissue by splashing raindrops, wind or insects are produced by the cleistothecia.
Nights are cool and it strikes in the spring, late summer, and autumn when days are cloudy and mild and damp.

A number of these races are restricted to certain species of turfgrass or to certain cultivars within a species.
The disease is observed on the surfaces of the leaves. It also impacts the bottom sides of leaves, young stems, buds, flowers and young fruit. Infected leaves turn yellow with patches of green may become distorted, and fall prematurely. Infected buds may fail to open.
