Finally, powdery mildew can be spread from one plant to another via wind, insects, and tools.
In conclusion, the main cause of powdery mildew is environmental conditions that favor the growth of the fungi, while other factors like poor air circulation, overcrowding, fertilizer, weakened plants, and the transfer of spores can all contribute to the disease’s spread.
What Conditions Cause Powdery Mildew To Grow?
Powdery mildew is a common fungal disease that can affect a range of plants, including vegetables, flowers, fruits, and ornamental plants.
It is identified by a white, powdery coating on the plant’s leaves and stems, which is composed of fungal spores.
In order for powdery mildew to take hold, the temperature should be between 60-80 degrees Fahrenheit and the air should have adequate circulation.
If the environment is still, the spores linger and the mildew can spread quickly through animals, wind, and rain.
Once the mildew is present, it grows on the surface of the plant, feeding on the cells of the leaves and stems.
This can lead to yellowing, curling, and dying of the leaves, as well as discoloration and distortion of the flowers and fruit.
Prevention is key in avoiding the spread of the disease.
Proper air circulation, avoiding wet, humid conditions, treating plants with a fungicide, isolating affected plants, and regular pruning and leaf removal can help reduce the growth and spread of the mildew.
