#5. Powdery Mildew
Category: Fungal Disease
Powdery mildew is a common disease that primarily affects pepper plant leaves, often appearing on older leaves before the fruit sets. However, it can develop at any stage of the plant’s growth.
Causes
Powdery mildew is caused by the fungus, Erysiphe polygoni, which is spread by wind-borne spores or through contact with infected plants. High humidity and temperatures between 60-80 degrees Fahrenheit (15.5-26.7 Celcius) can also create favorable conditions for the disease.
Signs
Plants affected by powdery mildew will have white, powdery patches on their leaves and stems. These patches will usually appear during the summer months. The disease can also cause yellowing and wilting of the leaves.
Treatment
Chemical treatments are available to treat powdery mildew, but they must be applied carefully and correctly to avoid damage to the plants.
Organically treating powdery mildew can be done by using a combination of baking soda and water. The baking soda will help to raise the pH level on the leaves, which can help to reduce the infection.
Prevention
Natural prevention of powdery mildew includes ensuring proper spacing between plants, avoiding overhead irrigation, and removing infected plants.
Chemical and biological control methods, such as fungicides and biological control agents, can also be used to prevent the spread of the disease.
Control
Once the disease has been identified, the infected plants should be removed and destroyed. Chemical control methods, such as fungicides, can also be used to treat infected plants.
