Rosemary & Powdery Mildew
Rosemary is a popular herb used for cooking, medicinal purposes, and decorating. But this fragrant plant can get powdery mildew, a disease caused by fungi that can kill plants if it isn’t treated quickly.
Powdery mildew is a fungal disease that affects a wide variety of plants, including rosemary. It is characterized by a white or gray powdery coating on the leaves, stems, and sometimes the flowers of a plant.
Powdery mildew is caused by a group of fungi called Erysiphaceae, which thrive in warm and humid environments. The fungus can infect roses, lilacs, peonies, phlox, zinnias, and many other plants.
In rosemary, powdery mildew can cause leaves to turn yellow and drop and can also affect the growth and production of the plant.
The fungus can harm the plant’s appearance, but it is not harmful to humans, and rosemary can still be used in cooking and medicine even if it has the fungus.
Identifying Infected Rosemary Plant with Powdery Mildew
It’s important to identify this infection so you can take the steps necessary to save your rosemary.
Powdery mildew on rosemary plants looks like a thin layer of white or grayish-white dust coating the leaves and stems. This fungus grows quickly in warm, damp places, and if it is not treated, it will spread over time.
To see if your rosemary plant has powdery mildew, look for white or yellow spots under its leaves. This could mean that fungal spores are growing. Another indication of an infected plant is curled-up leaves or stunted growth; both are signs that something isn’t right with the rosemary’s health.

Powdery Mildew’s Influence on Rosemary Plant
Oidium neolycopersici, the fungus that causes powdery mildew, can affect rosemary at any stage of growth and, if left untreated, can seriously harm the plant.
Inside the rosemary plant, powdery mildew can cause damage. The fungus can invade the stem and branches, rendering them fragile. As a consequence, the plant is more susceptible to wind and other environmental factors.
Powdery mildew not only damages the plant’s appearance, but it can also stop rosemary from growing and making flowers. The fungus can make it harder for the plant to make food from light, which can slow its growth and make it make less oil that can be used in cooking and medicine.
If you don’t do anything to stop it, the fungus can spread quickly, causing serious damage to the leaves and affecting the bush’s or tree’s overall health.
The good news is that there are ways you can prevent and treat powdery mildew on rosemary plant in your garden.
Safety Concerns for Consuming Rosemary With Powdery Mildew
Powdery mildew is hard to answer when it comes to whether or not it is bad for people to eat. Even though the fungus that causes powdery mildew is not dangerous to humans, it may not be a good idea to eat a lot of a plant that has a lot of it.
Eating rosemary with a small amount of powdery mildew on it is considered safe. But if powdery mildew covers a large part of the plant, it might be best to avoid eating it. This is because the fungus can reduce the quality of the rosemary and the oil yield and affect the chemical composition of the oil.
Although the fungus itself is not poisonous, it may not be a good idea to eat a heavily infected plant because it can change the quality of the rosemary and oil. It’s best to be safe and avoid eating plants that have a lot of disease.
