Powdery Mildew (Podosphaera lupuli)

This fungal disease is common in LA Hybrids when humidity is high and airflow is restricted. It presents as a white, talcum-like coating on the leaf surfaces, which can eventually lead to leaf necrosis and reduced bulb vigor.

Very Common

Botrytis Lilianum (Lily Botrytis Blight)

While typically known for brown blotches, early stages of Botrytis can sometimes appear as fuzzy, whitish fungal growth on petal edges or leaf tips in humid conditions. This pathogen thrives in the damp environments often found in lily beds.

Common

3 Improve air circulation around your lilies and avoid overhead watering to ensure the foliage dries quickly, as dampness promotes Botrytis growth.
warning

Mealybug Infestation

Mealybugs are small insects that secrete a white, waxy, cotton-like substance to protect themselves. In LA Hybrids, they often congregate at the leaf axils or under the scales of the bulb.

Common
