Management: To manage leaf spot, remove infected leaves immediately. Make sure to keep the plant dry, especially in humid weather, to prevent the spread of the fungus. Apply a fungicide to the plant every two weeks or as needed.
2. Powdery Mildew: Powdery mildew is another fungal disease that affects Cestrum laurifolium. It forms a powdery white coating on the leaves, which can stunt the growth of the plant if left untreated.
Management: Remove infected leaves immediately and apply a fungicide to the plant. Avoid overhead watering as it can promote fungal growth. Make sure the plant has good air circulation and is not overcrowded.
Common Pests
1. Spider Mites: Spider mites are small, spider-like insects that feed on the leaves of Cestrum laurifolium. They form webs on the leaves, which can cause the plant to look unsightly. Infected leaves will also turn yellow and eventually fall off.
Management: Wash the leaves with a strong jet of water to remove the mites. Apply an insecticidal soap every two weeks or as needed. Make sure to keep the plant well hydrated as spider mites are attracted to dry conditions.
2. Scale Insects: Scale insects are small, armored insects that feed on the sap of the plant. They leave a sticky residue on the leaves, which can cause mold growth. Infected leaves may also turn yellow and fall off.
Management: Remove infected leaves and apply an insecticidal soap to the plant every two weeks or as needed. You can also use a cotton swab dipped in rubbing alcohol to remove the scales from leaves and stems.
By following these disease and pest management tips, you can help keep your Cestrum laurifolium L'Hér. healthy and happy.
