One of the most widespread plant diseases is powdery mildew. This common fungus thrives best in climates that are warm and dry. Powdery mildew appears as a white fuzzy fungus on plants. It’s easily recognized by the spots and patches of white and gray mold that appear on plant leaves and stems. When allowed to grow uncontrolled, powdery mildew will quickly take over a plant and ultimately cause its demise.<\/span><\/p>\n

While many plants are vulnerable to powdery mildew, many others are resistant to infection. If the disease is a problem in your garden, you can help mitigate the problem by choosing disease-resistant plants to grow.<\/span><\/p>\n

There are also many treatments you can purchase to help plants that have become infected. Platt Hill Nursery sells a range of powdery mildew solutions for gardeners. If you’re wondering how to get rid of powdery mildew, the professionals at Platt Hill Nursery can help.<\/span><\/p>\n

What is Powdery Mildew?<\/b><\/h2>\n

 <\/p>\n

Powdery mildew is a fungus that affects almost all types of plants, from vegetables to flowers, fruit trees to forest trees. Powdery mildew gets its name from its appearance: white and gray colored, and powdery in texture. It appears on the surface of the leaves and can be found on other plant parts as well. After powdery mildew has infected a part of the plant, the leaves may turn yellow, and then brown. Powdery mildew can also cause leaves to become shriveled, dry, and distorted.<\/span><\/p>\n

Powdery mildew is not just one type of fungus. Different types of powdery mildew affect different types of plants. For example, a powdery mildew found on a rose is not the same as a powdery mildew found on a squash. Powdery mildew needs a living plant to grow on, so when the plant dies, so does the mildew.<\/span><\/p>\n

Powdery mildew produces spores that spread through the air. Water can prevent powdery mildew from spreading, so powdery mildew is most common in semiarid regions and less common in areas where high amounts of rainfall occur. Powdery mildew prefers warm days and cool nights. When leaf temperatures rise above 90\u00b0F, powdery mildew can die. Greenhouse conditions are often good for powdery mildew fungi, so sometimes growing plants in these conditions can be difficult. It’s important to use best practices for controlling powdery mildew in this type of environment.<\/span><\/p>\n

Powdery Mildew Life Cycle<\/b><\/h3>\n

Powdery mildew is a white mold that grows on living plants. On plants that survive from one season to the next, powdery mildew survives from one season to the next. On trees, it can survive on the bark of branches as well as on stems.<\/span><\/p>\n

Powdery mildew grows on the surface of affected plant parts in thin layers called <\/span>mycelium<\/span><\/i>. Spores of powdery mildew are produced on the upper leaf surface, on fruits, flowers, and on herbaceous stems.<\/span><\/p>\n

The wind carries the spores of powdery mildew to new hosts. When leaves are dry, this is when powdery mildew spreads best. If the leaves become wet and stay wet, this kills the spores of powdery mildew and prevents them from spreading.<\/span><\/p>\n

 <\/p>\n

Which Plants Are Most Susceptible to Powdery Mildew?<\/b><\/h2>\n

There are many species of plants, trees, shrubs, field crops, and garden plants that are susceptible to powdery mildew. The following are examples of plants that may become infected with powdery mildew:<\/span><\/p>\n
