Name a common disease that affects floral crops.

Powdery mildew is a prevalent fungal disease that affects a wide range of floral crops. This disease is characterized by white or grayish powdery spots on the surface of leaves and blooms, which can reduce the overall aesthetic appeal of the flowers and hinder their growth.

Powdery mildew thrives in warm, dry environments, particularly when humidity levels fluctuate, making certain flowering plants particularly susceptible. Managing this disease often involves improving air circulation around the plants, applying fungicides, or utilizing resistant varieties, highlighting its significance in floriculture.

While root rot, leaf spot, and blight are also common plant diseases that can affect floral crops, powdery mildew stands out due to its distinct appearance and the specific conditions under which it develops, making it a focus for both growers and researchers in the field of floriculture.
