Identification and Treatment

Borage is a beautiful and useful herb that is popular in many gardens. It has pretty blue flowers, and its leaves and flowers are used for culinary and medicinal purposes.

Common Borage Plant Diseases

1. Powdery Mildew

Powdery mildew is a fungal disease that affects many plants, including borage. It appears as white or grayish powdery growth on the leaves, stems, and flowers of the plant. Powdery mildew can weaken the plant and cause it to produce fewer flowers.

Treatment: The best way to prevent powdery mildew is to keep the plant dry by providing good air circulation and watering at the base of the plant. If the disease has already appeared, remove infected leaves and spray the remaining foliage with a fungicide containing sulfur or potassium bicarbonate.

2. Leaf Spot

Leaf spot is a bacterial disease that causes brown spots on the leaves of borage. These spots can merge together, causing the leaves to turn yellow and fall off.

Treatment: Remove infected leaves and destroy them immediately to prevent the spread of the disease. Spray the remaining foliage with a copper-based fungicide.

3. Root Rot

Root rot is a fungal disease that affects the roots of borage plants, causing them to rot and die. The plant may wilt, have stunted growth, or turn yellow.

Treatment: The best way to prevent root rot is to provide well-drained soil and avoid overwatering. If root rot has already set in, remove infected plants immediately and treat the soil with a fungicide containing Trichoderma.
