Disease Management
Several diseases can affect Silene antirrhina L. var. confinis Fern. Some of the most common diseases include gray mold, root rot, powdery mildew, and leaf spot.
Gray Mold
Gray mold is a fungal disease that affects the leaves, stems, and flowers of the plant. To manage this disease, you should remove all infected plant parts and dispose of them immediately. Additionally, ensure that your plant receives adequate spacing and airflow to prevent the spread of the disease.
Root Rot
Root rot is another fungal disease that affects the roots of the plant. It often occurs due to overwatering and poor drainage. To manage root rot, ensure that your plant is not overwatered, and the soil has proper drainage. If the disease has already infected your plant, consider repotting it in fresh soil.
Powdery Mildew
Powdery mildew is a fungal disease that affects the leaves and stems of the plant. It appears as a white, powdery substance on the plant's surface. To manage powdery mildew, you can try spraying your plant with a fungicide. Be sure to follow the instructions on the fungicide carefully.
Leaf Spot
Leaf spot is a fungal disease that appears as brown or black spots on the leaves of the plant. To manage leaf spot, you can remove all infected leaves and dispose of them immediately. You should also avoid getting water on the leaves of the plant, as leaf spot thrives in moist environments.
Pest Management
Several pests can also affect Silene antirrhina L. var. confinis Fern. Some of the most common pests include aphids, spider mites, and snails.
Aphids

Spider Mites
Spider mites are tiny insects that feed on the underside of the plant's leaves. They appear as small, reddish-brown dots on the leaves. To manage spider mites, you can spray your plant with neem oil or insecticidal soap. You can also try washing your plant with a strong jet of water to dislodge any spider mites that might be present.
Snails
Snails are a common garden pest that feeds on the leaves of the plant. To manage snails, you can create a barrier around your plant using a copper tape or crushed eggshells. Additionally, you can handpick any snails that you see on the plant. Alternatively, you can use snail bait, but be sure to follow the instructions on the label carefully.
