Common Fungal Diseases
- Botrytis blight: Causes brown spots, moldy growth, and wilting of leaves and flowers.

- Fusarium wilt: Leads to yellowing, wilting, and eventual plant death due to root rot.
Preventative Measures
Prevention is the best strategy to protect lily leaves from fungal diseases. Implementing good cultural practices can significantly reduce the risk of infection.
Proper Planting and Spacing
Plant lilies in well-drained soil with adequate spacing to ensure good air circulation. This helps keep foliage dry and discourages fungal growth.
Watering Techniques
Water lilies at the base early in the day to allow leaves to dry before evening. Avoid overhead watering, which can create a moist environment favorable to fungi.
Sanitation Practices
Regularly remove and destroy fallen leaves, dead flowers, and plant debris. Disinfect gardening tools after use to prevent spreading pathogens.
Management of Infected Plants
If fungal infections are detected, prompt action is necessary to prevent spread. Remove affected leaves and dispose of them away from healthy plants.
Fungicide Treatments
Apply appropriate fungicides labeled for lily diseases. Follow the manufacturer’s instructions carefully, and reapply as recommended for effective control.
Monitoring and Follow-up
