👉 Hooperia is a type of plant disease that occurs when infected leaves or stems of plants develop yellow or brown spots and produce spores. It can be caused by several factors, including infection from fungi, insects, or diseases like powdery mildew, which are spread through the soil and air. Symptoms include yellowing, discoloration, and abnormal growth patterns on affected parts of the plant. Hooperias can lead to crop loss if not properly managed or treated.
