mildu is incorrectly written and should be written as "Mildu or mildew." being its meaning:
Mildu is a distortion of the English word Mildew. Means rust. Mildew is a form of fungus that differs by its balnquecino color. Rust, white fungus, oidium, lama, powdery mildew, ash or blight. They belong to the Erysiphales family. They are easy to treat, because sometimes only to place the plant in places with good light and aeration is enough.
